Abstract:
Forest resources are one of the most important resources which men are survival of. We studied sustainable development tactics of regional forest resources . Volume model, describing the growing process of a tree, was built to establish the relationship between the age of grown up and the age of grow stagnation; also 1-D dynamic discrete model was established, considering the characteristic of number of trees in different ages in the condition that there is only a single kind of tree in the forest firstly; then multidimensional dynamic discrete model was formulated, providing the best felling policy that can meet lumber demand and have better age of stand structure. The simulation results show that the age of stand structure finally reach steadiness in one million hectares. Regional forest achieve sustainable development.

Abstract:
On 16 June 1837, at a little after six o'clock in the morning, a train of cars carrying lumber and gravel and crowded with twenty or more Irish track laborers and other workmen left the Boston depot of the Boston & Worcester Railroad Corporation bound for Worcester. About four miles out, just after the train had passed the City Mills and was nearing the Brookline road, a wheel on one of the cars broke. The train was thrown from the tracks. Two men were killed and several others severely injured.Among the injured was a man named Gilham Barnes, engaged by the Corporation about two weeks before to carry out maintenance work on several bridges between Boston and Worcester. On the previous day, Barnes, his brother Luther, and one of the men who worked with them had ridden the same train (an unscheduled track maintenance train known to the corporation as the “gravel” train) as far as the Arsenal bridge, which carried the railroad over the Watertown road in Brighton, to deliver materials and tools. On the morning of the sixteenth, Barnes sent the others by wagon via the Mill Dam toll road to begin work on the Arsenal bridge while he made arrangements with the conductor of the gravel train for additional materials to be carried to the Worcester bridge. Barnes intended, it would seem, to ride the gravel train as far as the Arsenal bridge where he would jump off and join his workmen. “We saw the train going out just after we paid [the] toll,” Luther Barnes later recounted. “Then near City Mills we saw shingles &c all about. I saw my brother running towards us. He waved his hat twice. And he held up his arm and I saw blood and flesh.”

Abstract:
In August 1919, a settlement house worker in Columbus, Ohio, filed a complaint in juvenile court against a seven-year-old girl whom I will call “Marie.” The complaint read, “Marie runs the streets continually. She is very irregular in her attendance at school, and is as dirty as a pig. She has been found in a lumber yard with a negro, and it was alleged by her associates that he raped her there. She goes into stores and begs.” According to the surviving records, Marie's “truancies from home” alerted settlement workers to the case. As a young child she reportedly began staying out late at night and loitering in the company of men and boys, and was threatened with being put out of the house when she was found alone with the African American man. By 1928, after Marie became an unwed mother at the age of sixteen, and had spent nine years in and out of child welfare institutions, a summary report contained the interesting typographical error that Marie's young life had strayed a distance of “six blacks from home.” As incidental as slipping “blocks” into “blacks” may have been in one sense, it captured a powerful truth. Marie violated key boundaries of sexual, gender, and racial purity that made a woman a candidate for respectable motherhood, and she paid dearly for these transgressions.

Abstract:
Pain in the back is the most common of all chronic pain disorders. Back pain and sciatica, or leg pain originating from injury to or pressure on the sciatic nerve, are major causes of disability in adults, occurring in 15% to 20% of the working-age population annually and 70% to 90% of adults at some point in their lives. Men and women are affected equally. The study was conducted prospectively in 60 patients of 18 to 60 years of age with documented chronic low back pain with sciatica. Thirty patients were treated in group-A with conservative treatment (NSAID+ therapeutic exercises+ superficial thermotherapy and ADL instruction) plus epidural steroid injection and 30 samples were treated in group B with conservative treatment only. Epidural steroid injection treatment group is significantly improved than conservative treatment group (p<0.05). There was more improvement of pain in group –A than in Group B ( p= 0.007) and SLR was more increased in group –A than group-B (p=0.03). So, epidural steroid injection is a effective treatment for lumber rediculopathy especially in acute phase. DOI: http://dx.doi.org/10.3329/medtoday.v26i1.21302 Medicine Today 2014 Vol.26(1): 09-11

Abstract:
Background. The matrilin, especially matrilin-3 (MATN3), are reported to play important roles in the pathophysiology of osteoarthritis (OA). To explore the relationship between MATN3 SNP6 (rs8176070) and primary OA, we conducted a community-based case-control study.Methods. A total of 732 community residents aged 40–84 years participated in the community-based study in Northeast China. After taking physical and radiographic examinations, 420 of the residents were diagnosed OA (216 women and 204 men). The other 312 individuals without any symptoms of osteoarthritis or signs in the radiographs (156 women and 156 men) were considered as healthy controls. After obtaining the DNA of case and control groups, genotypes of the MATN3 SNP6 were determined by polymerase chain reaction followed by restriction enzyme digestion. The numbers of patients with different OA subtypes were also calculated.Results. The distribution of genotypes and alleles of the MATN3 SNP6 between OA patients and controls was different significantly. The BB carrier tends to be associated with the increased osteoarthritis (P= 0.025, OR = 1.724, 95% CI = 1.071–2.77), especially the knee osteoarthritis (P= 0.021, OR = 2.402, 95% CI = 1.141–5.060) and lumber osteoarthritis (P= 0.020, OR = 1.880, 95% CI = 1.103–3.204). Bb carrier increased hand osteoarthritis risk (P= 0.002, OR = 5.380, 95% CI = 1.828–15.835). The B allele might have an effect on the increased knee osteoarthritis (P= 0.000, OR = 3.143, 95% CI = 2.283–4.328).Conclusion. These findings suggest that the MATN3 gene polymorphism might be associated with osteoarthritis in the Chinese Han population.

Abstract:
Abstract The uses of enslaved labor outside the context of staple crop production become evident through an examination of colonial Somerset County, the southernmost Maryland county on the Chesapeake Bay’s Eastern Shore. By the early eighteenth century, conditions in Somerset amounted to something of a paradox. The county’s planters were thoroughly embedded in the larger Chesapeake plantation society and replicated, insofar as they were able, the features of that society, including the use of slave labor and cultivation of tobacco. Yet poor soil conditions pushed residents to the edges of the tobacco economy. Unable to grow tobacco profitably, Somerset’s men and women identified alternative export commodities that were more suited to the resources at hand, including lumber, meat, and ships. In addition, many Somerset residents were active in an expanding coastwide trade that linked economic activity in the county to markets elsewhere in the colonies. Russo examines the allocation of enslaved labor in Somerset’s diversified economy using information drawn from judicial, tax, probate, and land records. Consideration of the evidence for Somerset County indicates that scholars need to devote more attention to the characteristics of slavery in anomalous areas that exist within broad staple-producing regions.

Abstract:
Background: In rare instances, massive over inflation of the cuff may lead to acute complications such as tracheal bleeding or rupture. This may be associated with post-operative complications like sore throat hoarseness of voice. The purpose of this study was to evaluate the ETT cuff pressure changes between supine to prone and supine to knee chest position in lumber disc surgery. Materials & Methods: Sixty patients, aged between 18 to 60 years of either sex, belonging to American Society of Anaesthesiology (ASA) physical status I to II undergoing elective lumbar disc surgery under general anaesthesia either in prone position or in knee-chest position were considered for this study. The patients were randomly allocated into two groups of 30 patients each. Group “p” was undergone operation in prone position and group “k” undergone operation in knee-chest position. The patients were connected to standard monitoring system such as non-invasive blood pressure (NIBP), electrocardiogram (ECG), pulse oxymeter, and capnometer. All patients were pre-medicated with inj. glycopyrrolate 0.2 mg and inj. fentanyl 2µg/kg iv 5-6 minutes before induction of anaesthesia and were pre-oxygenated with 100% oxygen for atleast 3 minutes. All the patients were induced with inj. propofol 2.5 mg/kg i.v. followed by inj. rocuronium at a dose of 1.2 mg/kg for facilitating tracheal intubation with reinforced ETT. The ETT size selected for men and women were 8.0-8.5 mm ID and 7.0- 7.5 mm ID (Mallinckrodt) respectively. Results: Group k patients showed higher cuff pressure change from 25 to 39.97cm of H2O compared to group p from 25 to 30.47 cm of H2O after change of position only. There was statistically significant different found between groups Sore throat was found significantly higher in group k compared to group p (20% vs 16.67%). Conclusion: The cuff pressure of the endotracheal tube should be monitored and managed properly after the position change from supine to prone and prone to knee chest position.

Abstract:
Objectives: To determine the prevalence of individuals with a traumatic spinal cord injury in Nairobi, Kenya. Methods: Retrospective quantitative data was extracted from records of 1st January 2010 to December 2014, at the NSIH. (N=320) participants met the inclusion criteria of all TSCI patients injured archived medical files, out these (n=217) were men, and (n=103) women, collected data was analyzed by SPSS version 23.0. Pearson chi-square was applied to test for association between variables, Student t-test was used to compare mean difference between groups, study Significance level was at p-value <0.05. Results: Mean age of the participants was 37.59 (SD= 15.038), the highest percentage age was 30-39 years old at (27.8%) followed aged 18-29 years at (26.6%). Male to female ratio was 2.1:1, highest prevalence occurred in 2010 and 2014 (20.5%), main cause of a TSCI transportation (49.1%), fall at (33.4%), assault (17.5%) common injury location was at lumber (53.1%), followed thoracic at (27.5%) cervical and sacral at (19.1%) and (0.3%) respectively. There were significantly more persons with paraplegia (54.1%) who had complete injuries than those with tetraplegia (19.6%). Other (27.3%) accounted for the TSCI patients with incomplete paraplegia and tetraplegia and no neurological deficits Conclusions: TSCI is a devastating condition to individuals; it has a high impact on QOL and ADL in low-income countries where there is an increase in manual labor and poor infrastructure, which predispose individuals to TSCI. Further studies need to be done to understand and compare epidemiological results, to inform appropriate prevention strategies that will decrease the burden of TSCI globally.

Abstract:
OBJECTIVE: To explore the prevalence of osteopenia and osteoporosis within a cohort of Pakistani postmenopausal women with respect to the lumbar spine and hip. METHODS: This cross-sectional study was conducted at Shifa International Hospital Islamabad, Pakistan from September 2019 to Feb 2020. Study comprised of 237 postmenopausal females who visited the outpatient department of the hospital. The T-scores of Bone Mineral density (BMD) data was collected and arranged in three groups: normal, osteopenia and osteoporosis. Data was analyzed to explore the distribution of the data and correlation analyses using R software version 3.6.3. RESULTS: Out of 237 females, majority were ranging in age from 61-70 years (n=110; 46.4%), followed by 51-60 years age group (n=60; 25.3%). Osteopenia was noted in 98 (41.4%) cases in lumber spine and hip area. Osteoporosis was found in 79 (33.3%) and 59 (24.9%) cases in lumber spine and hip region respectively. Mean T score was -1.775±-2.000 and median T score was -1.469 for lumber spine and hip. T-scores distribution of lumbar spine and hip indicated the highest proportion having a sore of -2 SD (n=60; 25.3% each), followed by -3 SD in 52 (21.9%) cases. Bone mass density was negatively correlated with age (p≤0.01). However, no significant difference was found among the BMD values of lumbar spine and hip region. CONCLUSION: Decreased bone density was a common occurrence affecting postmenopausal females and there is increase in degenerative bone loss with increasing age. Hip and lumbar spine region are equally affected by degenerative bone loss.

Abstract:
Introduction: Lumbar stabilization and McKenzie exercises are becoming a popular trend for managing chronic low back pain though it is currently not known whether lumbar stabilization exercises produce better results in improving functional status compared to McKenzie approach. The purpose of this study was to determine the effectiveness of the McKenzie approach versus lumbar stabilization in the treatment of chronic low back pain. Material & Methods: This was a randomized controlled trial. Lottery method was used to randomly divide individuals who fulfilled inclusion criteria into 2 groups. Assessments of the patients were done in OPD. Baseline assessment was done on day 1 and post intervention assessment was done after 2 weeks. A total of 8 treatment sessions spread across 2 weeks were given (4 days per week). Data were assessed at baseline level and post intervention. Data was entered and analysed by SPSS version 21. Results: A total of 28 females and 02 males (mean age of 50.88 ±12.29) participated in the study. After 02 weeks of intervention, both treatment groups showed improvement in decreasing pain and improving functional status. The lumber stabilization group showed significant gains on Numeric Pain Rating Scale and (p=0.001) and Modified Oswestry Disability Index (p=0.001) compared to the Mckenzie group. Conclusion: Patients in both lumber stabilisation and McKenzie groups showed significant improvement, however, the patients in lumbar stabilization group were superior than the patients in McKenzie group on the selected outcomes.

Abstract:
Introduction: Low back pain is one of the most common complaints in clinical practice with life time prevalence ranging from 65-80%. The annual prevalence of low back pain ranges from 15% to 45% but is largely dependent on population. Major cause of low back pain leading to severe morbidity throughout the world affecting mainly the young population is lumbar disc prolapse. Prolapsed intervertebral disc is an important cause of spondylogenic backache. Conservative treatment is often preferred for LDH, but patients who fail to respond to this are treated with surgery. Surgical treatment aims to remove the herniated nucleus pulposus to the largest extent possible to relieve nerve compression while minimizing spinal instability. Aim of the Study: The aim of this study was to assess the functional Outcome of open conventional discectomy among patients with prolapse lumbar intervertebral disc or lumbar herniated disk. Methods: This was a prospective observational study and was conducted in the Department of Orthopaedics Surgery, Square Hospitals Ltd, Dhaka, Bangladesh during the period from January 2008 to December 2020. We included 300 patients with prolapse lumbar intervertebral disc undergoing open conventional discectomy in our study. Result: In our study we found majority (36%) of our patients was aged 41-50 years and most of our study patients were male (70%) compared to female (30%). We found the mean age was 44.73 ± 8.9 years. Among all patients 78% had lower lumber problem & 22% had upper lumber problem. Most of our patients (44.5%) had L4-L5 level, followed by 31.5% had L5-S1 level. We found the mean vas score for leg pain and back pain in preoperative period significantly reduced at postoperative 2nd week, 3rd month, 6th month and 1st year. The mean ODI score was 56.24 ± 4.18 in preoperative period. At postoperative 1st year follow up the mean score significantly reduced to 3.26 ± 2.64 in our study. Majority (37%) of our patients had good outcome, followed ....

Abstract:
Background:Spondyloarthritis (SpA) is characterized by significant radiographic changes in the spine. The structural spine damage can be assessed using several scorings such as the Bath AS Radiology Index (BASRI) and the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS).Objectives:We aimed to identify factors associated with structural damage in the spine using these scores.Methods:We conducted a cross-sectional study including patients with SpA diagnosed according to the assessment of Spondyloarthritis International Society criteria.To assess the radiographic involvement of the spine, we used the mSASSS, the BASRI-spine (BASRI-S), the BASRI-lumber (BASRI-L) and the BASRI-cervical (BASRI-C).Disease activity was assessed using the BASDAI and ASDAS-CRP.Results:Among the 112 patients, 72.32% were men. The mean age was 43.78 ± 12,91 years. The mean age at diagnosis was 37.8 ± 13.45 years. The diagnostic delay of 37,8 ± 46 months.Forty-nine patients were smockers (43.8%).The mean BASDAI score and ASDAS–CRP score were 4.04 ± 1.99 and 3.30 ± 0.87.The mean ESR and CRP were 36.21 ± 27 (mm/H) and 31.28 ± 47.25 mg/LThe mean BASRI-S was 3,99 ± 21,96 and the mean mSASSS was 10,26 ± 15,41.Twenty-five patients (22.3%) had non-radiographic axial SpA.Men had higher BARSI-L (1.36 vs 0.7, p= 0.045) and BASRI-S (4.3 vs 3.09; p=0.047) than women.Moreover, smokers’ patients had higher mSASSS (14.07 vs 7.02; p=0.031), BASRI-C (1.23 vs 0.62; p=0.031), and BASRI-S (4.82 vs 3.35; p= 0.009) than nonsmokers’ patients.A positive correlation was noted between age and BASRI-C (r= 0.260, p=0.012). There was no correlation between age at the onset of SpA and structural spine damage.We found a positive correlation between disease duration and the following scores: BASRI-C (r=0.245, p=0.018) and BASRI-S (r=0.274, p=0.003).Patients with non-radiographic axial SpA had lower mSASSS (4.05 vs 12.14; p=0.034), BASRI-s (1.2 vs 4.9; p< 10-3), and BASRI-L (0.42 vs 1.4; p=0.003) than patients with radiographic axial SpA.There was no correlation between the radiographic index and BASDAI and ASDAS-CRP.Conclusion:We confirmed previous observations that male gender, smoking and disease duration are associated with structural damage in the spine [1].However, CRP and other inflammatory biomarkers were not associated with radiographic evidence of spine involvement.As observed in previous studies, the radiographic spine damage did not correlate with disease activity (BASDAI) [1].References:[1]Sari I, Haroon N.

Abstract:
Abstract In this research, flexural properties of mill-run, in-grade red and white oak lumber from a single mill and commercially available laminated hardwood composite were evaluated. Structurally graded green (wet) freshly sawn red and white oak 5 by 10-cm (2 by 4-in) nominal lumber as well as glue-laminated hardwood composite billets were tested in bending and their modulus of rupture (MOR) and modulus of elasticity (MOE) properties were developed. It is well documented that MOR and MOE are two major indicators to evaluate flexural strength of wood lumbers. From these data, summary statistics, design values, and mean separations were calculated and reported. Overall, the red and white oak lumber performed similarly to structural No. 2 grade material. The hardwood composite billets were highly uniform. Each of the three materials demonstrated a reasonably good relationship between MOE and MOR, thereby suggesting that MOE could be used as a selection criterion for strength in a commercial use situation.

Anterior vertebral fractures (VF) were assessed by lateral spine radiographs. Comparison of patients with and without NAFLD was done by SPSS.20. Multiple regressions were made to explain osteoporosis and VF with models including NAFLD and other risk factors. Significance was defined by p under 0.05.Results:We have included 172 RA patients, mean age was 55.4±11.9 years. Ninety per cent were females. Their average BMI was 26.8±5.47. Hypertension was diagnosed in 23.8% and 16.3% had diabetes. Forty per cent (40.1) had osteoporosis, 27.3% (47) had NAFLD. RA patients with NAFLD were older (p=0.04), obese (p=0.003), frequently associated to diabetes (p=0.02), Sjogren’s disease (p=0.001), higher total cholesterol (p=0.02) and gamma-glutamyl transferase (GGT) (p=0.002). Comparison tests did not reveal any associations with fractures, BMD or osteoporosis. In multiple regression models, patients with NAFLD and altered liver enzymes were associated to VF (p=0.04, OR=4.7[1.05-21.69] but not to BMD when adjusted on age (p=0.02), BMI (p=0.02), diabetes, menopause and Sjogren’s disease.Conclusion:NAFLD was frequent among our RA patients and was associated to VF prevalence in this study but not to BMD.References:[1]Mantovani A, Dauriz M, Gatti D, Viapiana O, Zoppini G, Lippi G, et al.

Abstract:
Underestimation of the disease osteoporosis in men is a serious problem, as osteoporotic fractures among men are frequent and they are accompanied by serious complications. Conducting DXA scans in men in Bulgaria is important to determine the state of their bone health. The aim of the study was to assess the bone mineral density (BMD) and T-score of the lumbar spine and of the hip through dual-energy X-ray absorptiometry (DXA) in men and to compare their values ​​in different age groups. Object of the study. Height, weight, body mass index (BMI) were assessed in 359 men with a mean age of 56 years (yrs.) ± 14 yrs., BMD and T-score of the lumbar spine and femoral neck were also examined. Methodology. Men are divided into the following age decades: 20-29 yrs., 30-39 yrs., 40-49 yrs., 50-59 yrs., 60-69 yrs., 70-79 yrs. and ≥80 yrs. Statistical program SPSS version 19.0 was used to access the data. The ANOVA test analyzes was applied to investigate if there are any statistically significant differences in BMD and T-score of the lumbar spine and femoral neck between the different age decades. Results and conclusions. 264 men were evaluated for total BMD of the lumbar spine and 95 men had results for BMD of the femoral neck. The mean total BMD of the lumbar spine differed significantly between the individual age decades in men (p = 0.000). The mean BMD values ​​of the femoral neck did not differ significantly in the different age decades in men (p = 0.07). 34 of 264 men (12.9%) were diagnosed with lumbar spine osteoporosis and 13 out of 93 men (14%) were diagnosed with femoral neck osteoporosis. The data obtained show a widespread prevalence of osteoporosis among men with a predominance of low values ​​of BMD on the axial skeleton in the age range between 60 and 79 years.

Abstract:
Objective. This study was aimed at evaluating the effectiveness and safety of percutaneous lateral lumbar discectomy (PLLD) in treating patients with lumber disc herniation.Methods. A total of 183 patients with lumbar disc herniation were recruited to receive PLLD surgery from April 2006 to October 2011. All the adverse effects were recorded during the follow-up at 1, 3, 6, and 12 months after PLLD. The clinical outcomes were determined by visual analog scale and Japanese Orthopaedic Association score.Results. The surgery was performed successfully in all patients (102 males and 81 females aged from 21 to 66 years) with a mean 16.6-month follow-up (range from 26 to 65 months). No postoperative complications, including intestinal and vascular complications, nerve injuries, and postoperative infections, were associated with PLLD. At one month after surgery, visual analog scale (3.12±1.44versus6.76±2.31,P<0.05) was significantly lower than the baseline and was sustained until 24 months after surgery (3.25±1.78versus6.76±2.31,P<0.05). Besides that, Japanese Orthopaedic Association score (25.25±3.21versus11.78±2.38,P<0.05) was increased when compared to the baseline.Conclusions. PLLD was a promising, mini-invasive, and effective treatment for lumber disc herniation.

Abstract BACKGROUND: Several authors have reported results obtained with the microendoscopic diskectomy (MED) technique, but the long-term outcome has not been described. This report summarizes our clinical experience with the lumbar MED technique with a long-term follow-up period. OBJECTIVE: To evaluate the efficacy of the MED for lumbar disk herniation and to report long-term outcome and complications (5-year follow-up). METHODS: One hundred twenty consecutive patients with lumbar disk herniation were treated with the METRx system.We included all types of lumbar herniated disks: contained, not contained, foraminal, and migrated disk herniations. The results were evaluated with the Visual Analog Scale (VAS) pain score, Oswestry Disability Index score, patient satisfaction questionnaire, and modified Macnab criteria. RESULTS: The average age of patients was 41 years; 65 were men and 55 were women. The most commonly affected level was L5-S1 (54.2%). The follow-up time after surgery was 5 years in all cases. We obtained good or excellent results in 75% of patients and regular results in 18%. Good subjective satisfaction was observed with surgery in 92% of patients. The mean decrease in the Oswestry Disability Index score was 52.8 ± 21.6; the mean decrease in leg VAS score was 6.1 ± 2.3; and the mean decrease in lumbar VAS score was 1.9 ± 3.3. Adjusted mean differences were statistically significant in all cases (P &lt; .05). CONCLUSION: MED not only reduces the incision, tissue damage, and postoperative period of incapacity but also offers long-term results comparable to those of conventional techniques.

Abstract:
This paper discusses the biomechanics and long-term results of posterolateral (PL) lumber fusion for degenerative lumbar spinal diseases. In the biomechanical study, the geometry of the finite element model is based on the L4-5 motion segment. The disc degeneration model was simulated by changing the interbody material properties. The behavior of the PL fusion model and the effects of the anterior elements on PL lumber fusion were studied in compression, flexion, and extension. In the clinical study, 40 patients with a mean age of 39 years (19 to 63) were treated with PL fusion and the mean follow-up period was 14 years. Clinical evaluation was made by the Japanese Orthopaedic Association (J.O.A.) score. Fusion success was determined by X-ray radiographs. Stress distribution results indicate that there were high stresses in the upper part of the grafted bone for PL fusion. The axial displacement of the L4 vertebral body and the stress of the grafted bone for PL fusion increased in the disc degeneration model. In flexion, the extension load stress concentrated on the L4 side of PL fusion model between transverse processes. Clinically, the J.O.A. score improved by 24 points postoperatively. Radiographically, the success rate of the fusion was 93%. The long-term results were so good that this technique can be recommended. It is suggested that the instability including the degree of disc degeneration is one of the important factors in PL lumbar fusion.

Abstract:
Background: The number of interventions on intervertebral discs rapidly increased and the treatment options for lumbar disc surgery quickly evolved. It is important that the safety and efficacy of all new innovative procedures be compared with currently accepted forms of treatment; however, the previous pairwise meta-analyses could not develop the hierarchy of these treatments. Objectives: The purpose of the study is to perform a network meta-analysis to evaluate the clinical results of 7 surgical interventions for the treatment of lumbar disc herniation. Study Design: Network meta-analysis of randomized controlled trials (RCTs) for multiple treatment comparisons of lumbar disc herniation. Methods: We performed a Bayesian-framework network meta-analysis of RCTs to compare 7 surgical interventions for people with lumbar disc herniation. The eligible RCTs were identified by searching Embase, Pubmed, the Cochrane Central Register of Controlled Trials (CENTRAL), and Google scholar. Data from 3 outcomes (success, complications, and reoperation rate) were independently extracted by 2 authors. Results: A total of 29 RCTs including 3,146 participants were finally included into this article. Our meta-analysis provides hierarchies of these 7 interventions. For the success rate the rank probability (from best to worst): percutaneous endoscopic lumber discectomy (PELD) > standard open discectomy (SOD) > standard open microsurgical discectomy (SOMD) > chemonucleolysis (CN) > microendoscopic discectomy (MED) > percutaneous laser disc decompression (PLDD) > automated percutaneous lumber discectomy (APLD). For the complication rate the rank probability (from best to worst): PELD > SOMD > SOD > MED > PLDD > CN > APLD. For the reoperation rate the rank probability (from best to worst): SOMD > SOD > MED > PLDD > PELD > CN > APLD. Limitations: The limitations of this network meta-analysis include the range of study populations and inconformity of the follow-up times and outcome measurements. Conclusions: This meta-analysis provides evidence that PELD might be the best choice to increase the success rate and decrease the complication rate, moreover SOMD might be the best option to drop the reoperation rate. APLD might lead to the lowest success rate and the highest complication and reoperation rate. Higher quality RCTs and direct head to head trials are needed to confirm these results.

Abstract:
The lumbar spine plays a very important role in our load transfer and mobility. Vertebrae localization and segmentation are useful in detecting spinal deformities and fractures. Understanding of automated medical imagery is of main importance to help doctors in handling the time-consuming manual or semi-manual diagnosis. Our paper presents the methods that will help clinicians to grade the severity of the disease with confidence, as the current manual diagnosis by different doctors has dissimilarity and variations in the analysis of diseases. In this paper we discuss the lumbar spine localization and segmentation which help for the analysis of lumbar spine deformities. The lumber spine is localized using YOLOv5 which is the fifth variant of the YOLO family. It is the fastest and the lightest object detector. Mean average precision (mAP) of 0.975 is achieved by YOLOv5. To diagnose the lumbar lordosis, we correlated the angles with region area that is computed from the YOLOv5 centroids and obtained 74.5% accuracy. Cropped images from YOLOv5 bounding boxes are passed through HED U-Net, which is a combination of segmentation and edge detection frameworks, to obtain the segmented vertebrae and its edges. Lumbar lordortic angles (LLAs) and lumbosacral angles (LSAs) are found after detecting the corners of vertebrae using a Harris corner detector with very small mean errors of 0.29° and 0.38°, respectively. This paper compares the different object detectors used to localize the vertebrae, the results of two methods used to diagnose the lumbar deformity, and the results with other researchers.

Abstract:
The Thoracic Erector spinae plane block (ESPB) has been incorporated in multimodal analgesia protocols since 2016. In a series of 20 Total Hip Arthroplasty (THA) patients, done under spinal anaesthesia, we studied the efficacy of Lumbar Erector spinae plane block (L-ESPB) for post operative analgesia. L-ESPB was administered at L4 with Ropivacaine 0.2% (0.4 mg/kg). Time to first analgesia (TTFA) request (mean 15.03 hours) and total opioid consumption in first 24 hours (mean 27.5 mg Tramadol) was noted. A median NRS at TTFA was 3.5. Our study demonstrates L-ESPB as an effective alternate technique for postoperative analgesia in THA patients. Keywords: Lumber ESP block, Hip Arthroplasty

Abstract:
Objective: The study compared the efficacy of fusion with non-fusion treatment for recurrent lumbar disc herniation. Materials & Methods: 60 patients including 30 – 65 years of either gender, with recurrent disc herniation and radicular pain from at least six months after primary lumbar disc surgery. Epidural scar tissues were separated and partly resected in patients with RLDH (recurrent lumber disc herniation) undergoing standard revision discectomy (Group A). Posterolateral fusion and trans-pedicular screw fixation were used in Group B. Following the implantation of a subcutaneous suction drain, the closure was performed as usual. The effectiveness was evaluated. The Japanese Orthopedic Association's core was used to measure clinical complaints before and after surgery. Results: Most of the patients (58.33%) were 46 – 65 years old. The mean recurrent time to primary surgery was 11.87 months. 60% of patients reported ? 12 months recurrent time in group B, and 66.6% in group A. Right side was noted in 26.67% of patients of both groups. The mean pre and post-operative JOA scores were 22.34 and 8.54, respectively. The mean recovery rate was 59.32%. This study reported the efficacy of non-fusion treatment versus fusion treatment as 16.67% and 63.33%, respectively. Conclusion: We concluded that the fusion treatment is better than the non-fusion treatment for recurrent lumbar disc herniation.

Abstract:
Object “Group and save” (type and screen) is commonly requested preoperatively in lumbar microdiscectomy. On average, less than 100 ml of blood is lost during lumbar microdiscectomy, and blood transfusion guidelines and resuscitation practice recommend that no transfusion would be required in almost all healthy patients with less than 750 ml of blood loss. The authors performed an audit of 319 consecutive lumbar microdiscectomies to determine if the practice of group and save can be justified. A telephone survey of the United Kingdom (UK) neurosurgical units to establish current UK neurosurgical practice was also conducted. Methods A telephone survey of all UK neurosurgical units and an audit of all patients who underwent primary lumbar microdiscectomy at our institution over a period of 2 consecutive years was performed. The health records of all patients were retrieved and critically reviewed. Information about hemoglobin measurements before and after surgery, group and save, and blood transfusion were collected. Results Thirty-two UK neurosurgical units were surveyed by telephone, with a 100% response rate. Group and save was commonly performed prior to lumbar microdiscectomy in 28 units (87.5%). The records of 319 consecutive patients who underwent lumber microdiscectomy were reviewed. All patients had group and save prior to lumbar microdiscectomy. No patient required a blood transfusion during or after surgery. The mean decrease in hemoglobin concentration was 0.8 g/dl in 121 patients who had postoperative hemoglobin measurements. Conclusions Blood transfusion and hemoglobin decrease following lumbar microdiscectomy is exceptionally rare. Group and save and postoperative hemoglobin measurements are therefore nonessential in all patients undergoing lumbar microdiscectomy, with potentially significant cost savings from not performing these tests.

Abstract:
Objective: To examine the associations between bone turnover markers (BTMs) and bone mineral density (BMD) in older adults aged 60–85 years. Methods: A total of 1124 men (mean age, 69.1 years) and 1203 women (mean age, 70.7 years) from the National Health and Nutrition Examination Survey 1999–2002 were included in this cross-sectional analysis. Independent variables were serum bone-specific alkaline phosphatase (sBAP) and urinary N-telopeptide (uNTx), which are biomarkers of bone formation and resorption, respectively. Outcome variable was lumbar BMD. The associations of sBAP and uNTx levels with lumbar BMD was examined using multivariable linear regression models. Results: sBAP was negatively associated with lumbar BMD in each multivariable linear regression model, and this negative association was stable in both men and women men (men: β = −0.0028, 95% CI: −0.0046 to −0.0010; women: β = −0.0039, 95% CI: −0.0054 to −0.0023). On the other hand, uNTx was negatively associated with lumbar BMD after adjustment of relevant covariables (β = −0.0328, 95% CI: −0.0523 to −0.0133). However, in the subgroup analysis stratified by gender, this negative association remained only in older women (β = −0.0491, 95% CI: −0.0751 to −0.0231). Conclusion: Our study suggested that elevated sBAP and uNTX levels correlated with decreased lumbar BMD, especially in older women. This finding indicated that maintaining BTMs at low levels may be beneficial to bone health for older adults.

Abstract:
493 Background: Many previous reports have shown that skeletal muscle loss (SML) is one of the prognostic factors for hepatocellular carcinoma (HCC) patients treated with sorafenib. However, there are few reports about the impact of SML for the HCC patients treated with lenvatinib. Therefore, we evaluated the relation between SML and overall survival (OS) of HCC patients treated with lenvatinib (LEN). Methods: We retrospectively analyzed 50 HCC patients treated with LEN from April 2018 to February 2019. We included 36 patients who continued LEN more than 8 weeks and evaluated CT scans before treatment and after 8 weeks. Skeletal muscle area was measured on axial image at the level of the third lumber vertebra (L3) using sliceOmatic. Skeletal Mass Index (SMI) was calculated by dividing the muscle area (㎠) with square of height (㎡). The definition of myopenia is based on the guideline described by the Japan Society of Hepatology (42㎠/㎡ in men and 38 ㎠/㎡ in women). ΔSMI is a chronological change of SMI for 8 weeks. We calculated decreasing rate of ΔSMI. We evaluated the relation between chronological change of SMI and OS. Results: The patients with myopenia at baseline were 12 (33.3 %). The decreasing rate of ΔSMI at 8 weeks was -2.57 % [-5.9, 0.2]. SMI had decreased in 27 patients (75 %) for 8 weeks. There was no significant difference between OS and baseline myopenia (p = 0.2), ALBI grade (p = 0.2), BCLC stage (p = 0.5), up to 7 in or out (p = 0.35), previous TKI treatment (p = 0.15), metastasis (p = 0.91), or vascular invasion (p = 0.12). However, the patients who had decreased SMI had significantly poor prognosis (p = 0.028). In backgrounds, there was no significant difference between patients with or without decreasing of ΔSMI, such as baseline myopenia (p = 0.7), ALBI grade (p = 0.4), BCLC stage (p = 1.0), Child Pugh score (p = 0.8), age (p = 0.6), sex (p = 0.3), up to7 in or out (p = 1.0), previous TKI treatment (p = 0.3), and relative dose intensity at 4 weeks (p = 0.9). Conclusions: There was no significant correlation between baseline myopenia and OS. However, chronological decreasing of SMI for 8 weeks was a prognostic factor of HCC patients treated with LEN. Therefore, monitoring and preventing of decreasing of skeletal muscle mass may be important.

Abstract:
A 74-year-old man developed a severe low back pain and a fever. In the initial examinations, a collapse of the L5 anterosuperior vertebral body and narrowing of the L4/5 disc space were identified on radiographs, and the laboratory data showed inflammatory results. A computed tomography (CT) and a magnetic resonance imaging showed collapse of L5. A needle biopsy was performed to make a diagnosis; however, an abdominal pain and a hypotension appeared after the biopsy. An abdominal CT showed a hematoma in the retroperitoneal space, and an angiography revealed a left fourth lumbar artery pseudoaneurysm. The pseudoaneurysm was treated with transcatheter placement of microcoils. Although haemorrhagic complications following needle biopsy are very rare, patients with large amounts of vertebral destruction may have unusual anatomical positions of the lumber artery. Therefore, surgeons should be aware of the possibility of lumbar artery injury during a needle biopsy and take care of prebiopsy plans.

Abstract:
Introduction: Posterior decompression and transforaminal lumbar interbody fusion (TLIF) using cage and bone graft is a surgical technique for treating lumbar spondylolisthesis. This procedure aims to relieve spinal pressure and stabilize the affected vertebral segments. Aim of the study: The aim of this study was to assess the clinical and functional outcomes of posterior decompression & transforaminal lumbar interbody fusion (TLIF) using cage and bone graft combined with stabilization in lumbar spondylolisthesis. Methods: This prospective observational study was carried out at NITOR, Dhaka, Bangladesh, during the period from January 2020 to December 2021. Total 15 patients with degenerative lumbar spondylolisthesis were included in this study. Result: The study assessed 15 patients undergoing surgery for spondylolisthesis, primarily aged 40-49, with a mean age of 46.4 years. Gender distribution was 40% male, 60% female. Pre-operative spondylolisthesis was mostly at L4/L5 (60%) and L5/S1 (40%). Post-op data showed significant reductions in slip angle and VAS scores for back and leg pain (all P<0.05). Foraminal and disc space height increased. Fusion rate was 86.66% per Hackenberg criteria. Motor deficit improved from 33.3% to 6.7% post-op. According to Macnab criteria, 73% had excellent functional outcomes and 26.66% experienced minor complications; no major complications were recorded. Conclusion: As observed from the result of this study, degenerative lumber spondylolisthesis can be treated with posterior decompression and transforaminal lumbar interbody fusion by using cage and bone graft with spinal stabilization. This method enhances neurological recovery, reduces pain and makes the patients able to return to work comfortably.

Abstract:
Abstract Background and Purpose. The causes of lumbopelvic imbalances in standing have been widely accepted by physical therapists, but there is a lack of scientific evidence available to support them. We examined the association between 9 variables and pelvic inclination and lumbar lordosis during relaxed standing. Subjects. Thirty men and 30 women with chronic low back pain (CLBP) for at least 4 months were examined (mean age=54.9 years, SD=9, range=40.4–69.8). Methods. Multiple linear regression modeling was used to assess the association of pelvic inclination and the magnitude of lumbar lordosis in standing with age, sex, body mass index (BMI), Oswestry Back Pain Disability Questionnaire (ODQ) scores, physical activity level, hip flexor muscle length, abdominal muscle force, and range of motion (ROM) for lumbar flexion and extension. Results. In women, age, BMI, and ODQ scores were associated univariately and multivariately with pelvic inclination. In men, lumbar extension ROM was related univariately to pelvic inclination; age, lumbar extension ROM, and ODQ scores were associated multivariately. Lumbar lordosis was associated univariately with only lumbar extension ROM for women and men. A weak correlation was found between angle of pelvic inclination and magnitude of lumbar lordosis in standing (r=.31 for women, r=.37 for men). Conclusion and Discussion. The odds ratio of having CLBP is increased if the score on the double-leg lowering test for abdominal muscles exceeds 50 degrees for men and 60 degrees for women. In patients with CLBP, the magnitude of the lumbar lordosis and pelvic inclination in standing is not associated with the force production of the abdominal muscles.

Abstract:
Introduction: Bone mineral density (BMD) is an important and measurable risk factor for osteoporotic fractures. Many studies showed higher bone mineral density and lower incidence of fracture in rural population compared to urban population. But all these studies were done in developed countries and very few studies were found in developing countries. This study was carried out to determine the bone mineral density (BMD) in women of both urban and rural dwellers and to evaluation the rate of occurrence of osteoporosis in these two groups.Method: A total 376 women with age range 35 to 85 were analyzed and divided in two groups. Group I rural (n204) and group II urban (n- 172), who were studied at two different Nuclear Medicine centers of Dhaka with different problems specially for low back pain and joint pain. Bone mineral density of lumbar spines (L2-L4) in anterior-posterior position and hip were measured using the Dual Energy X-Ray Absorptiometry-DEXA (Norland XR36). The T- scores were calculated and results were compared between rural and urban women. The history of physical activity, dietary intake of calcium, smoking habit, number of parity and socio-economic condition was also compared with BMD.Results: The mean T score of lumber spines in rural group was -2.31±1.10 and in urban group was -1.78±1.03. The hip of rural group showed mean T score -3.11±1.09 and urban group -3.02±1.09. Mean bone mineral density was lower in rural women than urban but statistically no significant difference was observed between the two groups (P <0.01 and P <0.02 respectively). In rural group 39.2 % cases showed osteoporosis in lumbar spines and 76.4% cases in hip. In comparison the urban group revealed osteoporosis in lumbar spines in 22.7% cases and in hip 40.9% cases.Conclusion: This study revealed lower bone mineral density in rural women than urban in our study population but this difference is statistically not significant.Bangladesh J.

Abstract:
Background: Compression fractures are common among osteoporotic patients and can be a significant source of pain and disability. Patients who suffer a compression fracture are most often treated conservatively. Case Presentation: This report presents the case of an 80-year-old non-hypertensive, non-diabetic male who presented to the hospital with severe acute lower back pain for one week previous. There was no associated past history of trauma. Initially, the patient was misdiagnosed as a case of simple musculoskeletal lower back pain, for which he received treatment, but the pain intensified over the following two weeks, prompting consultation with a neurologist. A physical examination and lumber x ray indicated signs of lumbar spondylosis with degenerative disc disease, for which the patient was prescribed paracetamol and non-steroidal anti- inflammatory drugs. However, no improvement was noted. Later, after three weeks, an MRI investigation was conducted. The findings revealed multiple disc narrowing levels throughout the lumbar spine. Based on these investigations, treatment was initiated with pregabalin. Tramadol was discontinued and visible improvements in the patient's condition were noted within a week. Later, the patient sought consultation from an orthopedic specialist. The doctor recommended additional imaging scans. Magnetic resonance imaging with contrast and computerized tomography scans were performed. Based on these imaging scans, a diagnosis of lumbar spine scoliosis and osteoporotic compression fracture at D12 was made, prompting the initiation of osteoporosis treatment with zoledronic acid. Conclusions: Initial diagnosis and management of osteoporotic vertebral compression fractures are important in preventing continued pain and preserving the quality of life in older patients. This case highlights the need for comprehensive evaluation, including MRIs, to discriminate acute fractures from other pathologies, facilitating appropriate intervention and osteoporosis management.

Abstract:
Studies to date have yielded conflicting results on associations between components of metabolic syndrome (MetS) and bone mineral density (BMD), particularly in men. This current systematic review and meta-analysis addresses the existing gap in the literature and aims to evaluate bone mineral density (BMD) at the femoral neck (FN) and lumbar spine (LS) in men diagnosed with MetS. The two study authors independently searched PubMed, Cinahl, Embase, and Web of Science up to 8 February 2022 for studies in English. The inclusion criteria were (i) diagnosis of MetS according to the NCEP-ATP III 2001 criteria; (ii) adult male demographic; (iii) analyzable data on BMD in at least two sites using dual-energy X-ray absorptiometry (DXA), and (iv) original observational studies. Case reports and non-English articles were excluded. We analyzed the results of seven studies providing data on bone density in men with MetS. Results: Based on random effect weights, the mean BMD of the femoral neck and lumbar spine were 0.84 and 1.02, respectively. The mean lumbar spine T-score was −0.92. In meta-regression analysis, the variances in mean BMD in the lumbar spine and femoral neck could not be significantly explained by BMI (lumbar BMD: Q = 1.10, df = 1, p = 0.29; femoral neck BMD: Q = 0.91, df = 1, p = 0.34). Our meta-analysis suggests normal bone mass in adult males with MetS. Due to the high heterogeneity in the seven analyzed studies and the lack of control groups in these studies, further research is needed to fully elucidate the associations between MetS and its components and BMD in men.

Abstract:
We studied the lumber characteristics of 148 trees taken for that purpose during commercial thinning operations in three Norway spruce (Picea abies [L.] Karst.) plantations, aged from 32 to 34 years, which had been attacked by the white pine weevil (Pissodes strobi [Peck]). The trees, with diameters ranging from 14 to 23 cm, were grouped into three quality classes according to the number of major deformations caused by the weevil. The effects of the deformations on rigidity, bending strength, wood density and lumber defects were examined. Results show that in general the deformations caused by the weevil do not affect the lumber properties of Norway spruce on sites of medium- to high-quality. For the three Norway spruce plantations, the mean values of the modulus of elasticity (MOE) of the lumber vary from 8510 to 9357 MPa, and for the modulus of rupture (MOR) range from 36.0 to 42.5 MPa, whereas wood density varies from 324 to 343 kg·m-3. For comparison purposes, the same measurements were taken on lumber from 38 trees in a white spruce (P. glauca [Moench] Voss) plantation that was unaffected by the weevil, but otherwise comparable to the Norway spruce plantation on one of the sites studied. The lumber properties from the Norway spruce taken from deformed or undeformed stems are 34% superior to the white spruce for the MOE, 20% for the MOR and 8% for wood density. The smaller knots in the Norway spruce could explain this difference. On the other hand, a visual classification of this type of wood reveals few differences in the lumber's bending strength or rigidity.

Abstract:
Objective: This study aimed to evaluate the frequency of cases in which patients were diagnosed with lumber spinal stenosis using MRI and later were categorized as having spondylolisthesis when evaluated through plain X-rays. Material and Methods: This retrospective study was conducted at the Ali Institute of Neurosciences, Irfan General Hospital from 2017 to 2022. All those patients were included in the study who underwent lumbar spine MRI between 2017 and 2022 with evident findings of spinal stenosis, patients who subsequently underwent plain X-rays of the lumbar spine, and patients with available medical records and imaging data for review. While all those were excluded who did not undergo plain X-rays following MRI. Data was analyzed using SPSS version 22. Descriptive statistics, such as frequencies and percentages, were used to summarize the categorical data while mean and standard deviation were reported for numerical data. Results: The mean age of the study population was 45 years, with a range from 26 to 65. Among the patients included in the study (1156), 380 were the cases missed initially on MRI and later diagnosed with spondylolisthesis on plain X-rays. This corresponds to a frequency of 33% of misdiagnosed spondylolisthesis cases based on MRI. Conclusion: This study highlights that the frequency of missed spondylolisthesis cases on lumbar spine MRI was one-third of the cases and the importance of additional imaging modalities, such as plain X-rays, for accurate diagnosis.

Abstract:
Background: Decompression (fenestration and discectomy) of lumber disc herniation is one of the most common surgical procedures done by neurosurgeons. The aim of this study was to evaluate the efficacy of per operative use of powdered vancomycin in reduction of early post-operative superficial surgical site infection in single level prolapsed lumber intervertebral disc surgery. Methods: This was a Quasi-experimental type of study carried out in the Department of Neurosurgery, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from October 2022 to September 2023. Results: In this study, the mean age was 42.2±10.5 years, ranging from 20 to 60 years. The highest incidence of prolapsed lumbar intervertebral disc (PLID) was in the vancomycin group among patients aged 41-60, with a male-to-female ratio of 1.7:1. Most PLID cases (59.4%) occurred at the L4/5 level. Out of 32 patients, only four (no vancomycin group) had an ESR above 75 mm/hr. On the 30th postoperative day, significantly increased CRP levels and signs of infection were observed. Among those with purulent discharge, 50% had Staphylococcus aureus, 25% had Staphylococcus epidermidis, and 25% showed no pathogen growth. Conclusions: In this study, we found that there is a significant effect of topical application of powdered vancomycin in addition to systemic antibiotic prophylaxis over the subcutaneous tissue following fenestration and discectomy in single level prolapsed lumber intervertebral disc and reduction in the incidence of superficial surgical site infection.

Abstract:
Objectives:To examine bone mineral density (BMD) in men with coronary heart disease (CHD), depending on the state of the muscle mass, strength and function.Methods:79 men aged over 50 years with verified CHD were examined (mean age 63 (57; 66) years).The BMD and T-criterion (standart deviation, SD) of the femoral neck and lumbar spine (L1-L4) were evaluated using dual-energy x-ray absorptiometry (DXA) on the Lunar Prodigy Primo bone densitometer (USA). The following reference intervals were used: normal BMD values (T-criterion ≥-1), osteopenia (OPe) (T-criterion from -1 to -2.5), and osteoporosis (OP) (T-criterion <-2.5).To assess muscle mass, the total area (cm2) of the lumbar muscles of the axial section at the level of the 3rd lumbar vertebra (L3) was determined using multispiral computed tomography on a 64-slice computer tomograph “Somatom Sensation 64” (Siemens AG Medical Solution, Germany). The ratio of the obtained index of the area of skeletal muscle to the square of the patient’s growth index determined the “ skeletalmuscular index L3” (SMI). The media considered the threshold value to be 52.4 cm2/m2.Results:The femoral neck BMD in the examined patients was 0.96 (0.89; 1.03) g/cm2, which corresponds to -0.50 (-1.00; 0) SD according to the T-criterion, in the lumbar spine -1.23 (1.11; 1.32) g/cm2and 0.4 (-0.50; 1.20) SD according to the T-criterion.In accordance with the recommendations of the European working group on sarcopenia in Older people (EWGSOP, 2010, 2018), the patients were divided into 3 groups: 31 patients without sarcopenia (group 1), 21 patients with isolated muscle loss (presarcopenia) (group 2) and 27 patients with sarcopenia (group 3).BMD in the femoral neck in the group of patients without sarcopenia was 0.96 (0.72; 1.26) g/cm2, which corresponds to -0.50 (-0.8; 0.2) SD according to the T-criterion, in the lumbar spine – 1.19 (1.10; 1.275) g/cm2and 0.1 (-0.6; 0.8) SD according to the T-criterion. BMD in the femoral neck in the group of patients with presarcopenia (group 2) – 0.995 (0.94; 1.04) g/cm2and -0.3 (-0.70; 0) SD according to the T-criterion, in the lumbar spine – 1.32 (1.24; 1.40) g/cm2and 1.20 (0.50; 1.90) SD according to the T-criterion. In patients with established sarcopenia (group 3), the following indicators of BMD and T-criterion were recorded: 0.95 (0.845; 0.98) g/cm2and -0.60 (-1.40; -0.40) SD and 1.23 (0.085; 1.31) g/cm2and 0.4 (-0.8; 1.1) SD in the femoral neck and lumbar spine, respectively.A comparative analysis of the results of the DXA found that patients with sarcopenia had a significant decrease in the BMD and T-criterion in the femoral neck compared to patients with presarcopenia (p=0.039 and p=0.040, respectively). There were no differences between the groups of patients without sarcopenia and with sarcopenia and presarcopenia (p>0.05).It was found that patients with sarcopenia had significantly lower BMD and T-criterion in the lumbar spine compared to patients with presarcopenia (p=0.017 and p=0.0165, respectively). The values of the BMD and T-criterion in the groups of patients without sarcopenia and with presarcopenia and sarcopenia in the lumbar spine were comparable (p>0.05).Conclusion:The presence of sarcopenia is associated with loss of BMD in the femoral neck and in the lumbar spine. The results obtained confirm the high probability of common pathogenetic links between OP and sarcopenia.Disclosure of Interests:None declared

Abstract:
In this study, the associations of cervical and lumbar paraspinal musculature based on a texture analysis of proton density fat fraction (PDFF) maps were investigated to identify gender- and anatomical location-specific structural patterns. Seventy-nine volunteers (25 men, 54 women) participated in the present study (mean age ± standard deviation: men: 43.7 ± 24.6 years; women: 37.1 ± 14.0 years). Using manual segmentations of the PDFF maps, texture analysis was performed and texture features were extracted. A significant difference in the mean PDFF between men and women was observed in the erector spinae muscle (p < 0.0001), whereas the mean PDFF did not significantly differ in the cervical musculature and the psoas muscle (p > 0.05 each). Among others, Variance(global) and Kurtosis(global) showed significantly higher values in men than in women in all included muscle groups (p < 0.001). Not only the mean PDFF values (p < 0.001) but also Variance(global) (p < 0.001), Energy (p < 0.001), Entropy (p = 0.01), Homogeneity (p < 0.001), and Correlation (p = 0.037) differed significantly between the three muscle compartments. The cervical and lumbar paraspinal musculature composition seems to be gender-specific and has anatomical location-specific structural patterns.

Objective: to investigate movement-based therapy (kinesitherapy) effectiveness in the rehabilitation of patients after lumbar microdiscectomy.Patients and methods. We enrolled 90 patients (33 men and 57 women, mean age — 59.78±12.0 years) after lumbar microdiscectomy due to the ineffectiveness of conservative management of discogenic lumbosacral radiculopathy. One-half of the participants (45 patients: 15 men and 30 women, mean age — 60.24±12.0 years) underwent kinesitherapy under the supervision of a physician; in other 45 patients (18 men and 27 women, mean age — 59.33±11.0 years), kinesitherapy was not included in the radiculopathy treatment protocol. We assessed pain intensity with visual analogue scale (VAS) and disability using the Roland-Morris scale (RMS) before surgery, ten days after the surgery, and 1, 3, and 6 months after surgery.Results and discussion. We observed a significant decrease in pain intensity - up to 4 points on the VAS, and an improvement in activities of daily living up to 10 points on the RMS 10 days after microdiscectomy. After six months, there was a decrease in pain intensity according to the VAS to 2 points in the kinesitherapy group and to 3 points in the group without kinesitherapy (p=0.088), as well as an improvement in activities of daily living according to RMS up to 5 points in the kinesitherapy group and up to 8 points in the group without kinesitherapy (p=0.003). Reoperations were required in two of 45 patients in the group without kinesitherapy (4.4%) and in one of 45 patients (2.2%) in the kinesitherapy group (p≥0.05).Conclusion. Kinesitherapy can improve functional recovery in patients after lumbar microdiscectomy.

Abstract:
Purpose The angles of thoracic kyphosis and lumbar lordosis determine the spinal alignment in the sagittal plane. The aim of this study was to compare the thoracic kyphosis and lumbar lordosis of male and female yoga practitioners with non-practicing participants and to determine the possible dependencies between sagittal spinal curvatures and somatic parameters, time spent on yoga exercise, and undertaking other physical activities in yoga practitioners. Methods The study involved 576 women and 91 men ages 18–68 years (mean = 38.5 ± 9) who were practicing yoga, and 402 women and 176 men ages 18–30 years (mean = 20.2 ± 1.3) as a control group. The angles of thoracic kyphosis and lumbar lordosis were measured using a Plurimeter-V gravity inclinometer. Results The two-way ANOVA demonstrated the influence of group (p < .0001) and sex (p = .03) on the angle of thoracic kyphosis, as well as the influence of group (p < .0001) and sex (p < .0001) on the angle of lumbar lordosis. It was noted that yoga practitioners had less pronounced thoracic kyphosis and lumbar lordosis and were more often characterized by normal or smaller thoracic kyphosis and lumbar lordosis than students from the control group. In yoga practitioners, the angle of thoracic kyphosis was positively correlated with age, body mass, BMI, and undertaking other forms of physical activity. The angle of lumbar lordosis was negatively correlated with body height and body mass. Conclusions The results suggest that yoga exercises can affect the shape of the anterior-posterior curves of the spine and may be an efficient training method for shaping proper posture in adults.

Abstract:
Background The majority of orthopaedic problems experienced by competitive swimmers are related to pain in the shoulder, low back, and knee. Three of 39 national swim team members were hampered in their performance due to lumbar disk herniation at an international competition in 2001. There has been no previous research into lumbar disk degeneration in elite competitive swimmers. Hypothesis Excessive competitive swimming activities accelerate lumbar disk degeneration. Study Design Case control study; Level of evidence, 3. Methods Fifty-six elite swimmers (high-load group, 35 men and 21 women; mean age, 19.6 years) and a control group of 38 university recreational level swimmers (low-load group, 24 men and 14 women; mean age, 21.1 years) were evaluated for lumbar disk degeneration using magnetic resonance imaging. We compared the prevalence of disk degeneration and the disk level between the 2 groups and further investigated the relationship among their symptoms, swimming styles, and disk degeneration. Results Thirty-eight (68%) elite swimmers and 11 (29%) controls had degenerated disks at various disk levels, and the prevalence was significantly greater in the elite swimmers (P = .0002). Comparison between the 2 groups of the prevalence of disk degeneration at each level revealed that the disk level of L5-S1 was significantly more frequently degenerated in the high-load group (P = .026). There was no significant relationship observed among the variables of low back pain symptoms, swimming strokes, and disk degeneration. Conclusion Excessive competitive swimming activities might exaggerate lumbar intervertebral disk degeneration, especially in the L5-S1 intervertebral segment.

Abstract:
Background: Nerve root compression is often inadequately understanding radicular pain due to prolapsed lumbar intervertebral disc, a common neurosurgical presentation. Inflammation is proved as an important etio-pathological component of radiculopathy, even after surgery. Methods: This cross-sectional intervention study conducted from March 2022 to September 2023. Data collected from 45 patients with prolapsed lumber intervertebral Disc, who underwent surgical intervention in Department of Neurosurgery, BSMMU. Results: The mean±SD age of the patients was 38.4±11.6 years, most of them 37 (82.2%) aged within 29 to 60 years. Majority 30 (66.7%) of them were male. Patients presented with pain, numbness and weakness was 45 (100%), 33 (73.3%) and 8 (17.8%) respectively. Among the participants most 36 (80%) had right sided and 9 (20%) had left sided radiation. The mean±SD level of pre-operative high sensitive C-reactive protein was 2.1±1.7. Pre-operative high sensitive C-reactive protein was significantly associated pre-operative, post-operative and mean change in visual analogue score (p<0.001, p<0.001, p= 0.006 respectively). Correlation of high sensitive C-reactive protein and VAS score (both pre and post-operative) were also statistically significant with p =0.017 and p <0.001 respectively. Conclusions: In our study, there is an association between pre-operative serum high sensitive C- reactive protein and post-operative radicular pain following surgical intervention in patients with prolapsed lumbar intervertebral disc.

Abstract:
OBJECTIVESpinopelvic parameters, such as the pelvic incidence (PI) angle, sacral slope angle, and pelvic tilt angle, are important anatomical indices for determining the sagittal curvature of the spine and the individual variability of the lumbar lordosis (LL) curve. The aim of this study was to investigate the influence of spinopelvic parameters and LL on adjacent-segment degeneration (ASD) after short lumbar and lumbosacral fusion for single-level degenerative spondylolisthesis.METHODSThe authors retrospectively reviewed the records of all short lumbar and lumbosacral fusion surgeries performed between August 2003 and July 2010 for single-level degenerative spondylolisthesis in their orthopedic department.RESULTSA total of 30 patients (21 women and 9 men, mean age 64 years) with ASD after lower lumbar or lumbosacral fusion surgery comprised the study group. Thirty matched patients (21 women and 9 men, mean age 63 years) without ASD comprised the control group, according to the following matching criteria: same diagnosis on admission, similar pathologic level (≤ 1 level difference), similar sex, and age. The average follow-up was 6.8 years (range 5–8 years). The spinopelvic parameters had no significant influence on ASD after short spinal fusion.CONCLUSIONSNeither the spinopelvic parameters nor a mismatch of PI and LL were significant factors responsible for ASD after short spinal fusion due to single-level degenerative spondylolisthesis.

Abstract:
Pelvic tilt can vary over time due to aging and the possible appearance of sagittal spine disorders. Cup position in total hip arthroplasty (THA) can be influenced due to these changes. We assessed the evolution of pelvic tilt and cup position after THA and the possible appearance of complications for a minimum follow-up of ten years.343 patients received a THA between 2006 and 2009. All were diagnosed with primary osteoarthritis and their mean age was 63.3 years (range, 56 to 80). 168 were women and 175 men. 250 had no significant lumbar pathology, 76 had significant lumbar pathology and 16 had lumbar fusion. Radiological analysis included sacro-femoral-pubic (SFP), acetabular abduction (AA) and anteversion cup (AV) angles. Measurements were done pre-operatively and at 6 weeks, and at five and ten years post-operatively. Three measurements were recorded and the mean obtained at all intervals. All radiographs were evaluated by the same author, who was not involved in the surgery.There were nine dislocations: six were solved with closed reduction, and three required cup revision. All the mean angles changed over time; the SFP angle from 59.2º to 60º (p=0.249), the AA angle from 44.5º to 46.8º (p=0.218), and the AV angle from 14.7º to 16.2º (p=0.002). The SFP angle was lower in older patients at all intervals (p<0.001). The SFP angle changed from 63.8 to 60.4º in women and from 59.4º to 59.3º in men, from 58.6º to 59.6º (p=0.012). The SFP angle changed from 62.7º to 60.9º in patients without lumbar pathology, from 58.6º to 57.4º in patients with lumbar pathology, and from 57.0º to 56.4º in patients with a lumbar fusion (p=0.919). The SFP cup angle was higher in patients without lumbar pathology than in the other groups (p<0.001), however, it changed more than in patients with lumbar pathology or fusion at ten years after THA (p=0.04).Posterior pelvic tilt changed with aging, influencing the cup position in patients after a THA. Changes due to lumbar pathology could influence the appearance of complications long-term.

Abstract:
The prevalence of osteoporosis is estimated to be 18% in men, but 30% of all fractures occur in men. With age, men experience a gradual decline in testosterone production and bone density. The rate of trabecular bone loss in the lumbar spine in men over age 50 can be double the rate of loss in men under age 50. Endogenous testosterone, estradiol, and their metabolites play a role in maintaining bone health, but their specific effects on bone turnover have been difficult to elucidate. Recently, large cohort studies have provided more detailed information confirming estrogen’s associations and further characterizing the effect of endogenous testosterone and its metabolites on bone mineral density and fractures. Very few clinical trials have assessed the impact of testosterone replacement therapy (TRT) on bone density and fractures in men. The few studies that have been conducted are generally small and not robust enough to show the true treatment effect of TRT and adequately determine its safety. In the absence of data on patient outcomes, it is important for pharmacists to understand the impact of drug therapy on biomarkers and surrogate markers of disease for optimal pharmacotherapy selection and monitoring.
