Abstract:

Abstract CASE DESCRIPTION A 12-year-old 32-kg neutered female crossbreed dog was treated for a large lumbosacral skin defect. CLINICAL FINDINGS The dog had sustained multiple, penetrating dog bite wounds to the lumbosacral and gluteal regions 5 days earlier. The referring veterinarian had initiated treatment with amoxicillin–clavulanic acid, which was continued at a dosage of 8.75 mg/kg, SC, every 24 hours at the referral hospital. Examination of the skin defect revealed a large subcutaneous abscess in the dorsal lumbosacral region with draining perimeter tracts at the wound margin. The partial-thickness wound measured 24 × 35 cm and had multifocal regions of necrosis extending caudally from the dorsal aspect of the T11 vertebra to the tail base. The skin defect was bounded by discolored and necrotic skin edges. TREATMENT AND OUTCOME The dog underwent extensive soft tissue wound reconstruction. A single, large, meshed full-thickness free skin graft was harvested from the left dorsolateral aspect of the thorax and grafted to the dorsal lumbosacral region, thereby enabling successful closure of the wound defect. Primary healing of the wound eventually occurred, without postoperative complications. CLINICAL RELEVANCE Use of a large, meshed full-thickness free skin graft led to a satisfactory outcome for this dog but required challenging postoperative management. Application of single, large, meshed full-thickness free skin grafts may be an option to manage large skin deficits in the lumbosacral area in dogs.

Abstract:

Neurofibromas are benign tumors of the peripheral nerve sheath. Spinal neurofibroma often asymptomatic. Symptoms may present include sensory changes. Neurofibroma mostly encountered cervical cord, difficult to distinguish from schwannomas. This slow growing tumor remodel the bone resulting pedicle thinning and posterior vertebral body scalloping. MRI shows hyperintense rim. Although this highly suggestive neurofibroma, occasionally also seen in schwannoma and malignant PNST. Treatment choice for symptomatic lesions is surgery. We are reporting a case of neurofibroma in the 5th lumbar and 1st sacral region.

Abstract:

We previously demonstrated that administration of norepinephrine, dopamine, and serotonin into the lumbosacral defecation center caused propulsive contractions of the colorectum. It is known that the monoamines in the spinal cord are released mainly from descending neurons in the brainstem. In fact, stimulation of the medullary raphe nuclei, the origin of descending serotonergic neurons, enhances colorectal motility via the lumbosacral defecation center. Therefore, the purpose of this study was to examine the roles of the noradrenergic nucleus locus coeruleus (LC) and dopaminergic nucleus A11 region in the defecation reflex. Colorectal motility was measured with a balloon in anesthetized rats. Electrical stimulation of the LC and A11 region increased colorectal pressure only when a GABAA receptor antagonist was injected into the lumbosacral spinal cord. The effects of the LC stimulation and A11 region stimulation on colorectal motility were inhibited by antagonists of α1-adrenoceptors and D2-like dopamine receptors injected into the lumbosacral spinal cord, respectively. Spinal injection of a norepinephrine-dopamine reuptake inhibitor augmented the colokinetic effect of LC stimulation. The effect of stimulation of each nucleus was abolished by surgical severing of the parasympathetic pelvic nerves. Our findings demonstrate that activation of descending noradrenergic neurons from the LC and descending dopaminergic neurons from the A11 region causes enhancement of colorectal motility via the lumbosacral defecation center. The present study provides a novel concept that the brainstem monoaminergic nuclei play a role as supraspinal defecation centers. NEW & NOTEWORTHY The present study demonstrates that electrical and chemical stimulations of the locus coeruleus or A11 region augment contractions of the colorectum. The effects of locus coeruleus and A11 stimulations on colorectal motility are due to activation of α1-adrenoceptors and D2-like dopamine receptors in the lumbosacral defecation center, respectively. The present study provides a novel concept that the brainstem monoaminergic nuclei play a role as supraspinal defecation centers.

Abstract:

Reconstruction of the lumbosacral junction is a considerable challenge for spinal surgeons due to the unique anatomical constraints of this region as well as the vectors of force that are applied focally in this area. The standard cages, both expandable and nonexpendable, often fail to reconstitute the appropriate anatomical alignment of the lumbosacral junction. This inadequate reconstruction may predispose the patient to continued back pain and neurological symptoms as well as possible pseudarthrosis and instrumentation failure. The authors describe their preoperative planning and the technical characteristics of their novel reconstruction technique at the lumbosacral junction using a cage with adjustable caps. Based precisely on preoperative measurements that maintain the appropriate Cobb angle, they performed reconstruction of the lumbosacral junction in a series of 3 patients. All 3 patients had excellent installation of the cages used for reconstruction. Postoperative CT scans were used to radiographically confirm the appropriate reconstruction of the lumbosacral junction. All patients had a significant reduction in pain, had neurological improvement, and experienced no instrumentation failure at the time of latest follow-up. Taking into account the inherent morphology of the lumbosacral junction and carefully planning the technical characteristics of the cage installation preoperatively and intraoperatively, the authors achieved favorable clinical and radiographic outcomes in all 3 cases. Based on this small case series, this technique for reconstruction of the lumbosacral junction appears to be a safe and appropriate method of reconstruction of the anterior spinal column in this technically challenging region of the spine.

Abstract:

Background: The lumbosacral angle (LSA), is a key morphometric parameter important in the management of patients with low back disorders. Aim: The study evaluated the relationship between age and lumbosacral angle of adult Nigerians. Methods: Two hundred and twenty-six (226) radiographs (113 males to 113 females) were obtained from Radiology departments of Federal Medical Centre (FMC), Owerri. Inclusion criteria were, lateral radiographs of lumbosacral region marked above 18 years of ages and only clear X-ray films were used.Using the Ferguson's approach, the lumbosacral angle was measured. All data obtained were expressed both in descriptive and inferential statistics. Results: Both male and female categories showed a progressive increase in lumbosacral angle across age groups, but later decreased in the age group of 60 years and above. The mean lumbosacral angle of male subjects was 35.74° while that of females was 41.46°. There was a significant difference (t = 3.16, p = 0.002) between the lumbosacral angle of male and female categories. However, there was a weak, positive correlation between age and lumbosacral angle of males (r = 0.187) and females (r = 0.392). Conclusion: The males had a lower mean lumbosacral angle compared to the females. Age was significantly correlated with lumbosacral angle in both sexes.

Abstract:

Background: A previous study examined the relationship between the sacral inclination angle (SIA), lumbosacral angle (LSA) and sacral horizontal angle (SHA) and spinal mobility in acute low back pain and chronic low back pain patients. We chose to investigate the lumbar lordosis angle, segmental lumbar lordosis angle, SIA, LSA and SHA in acute and chronic low back pain (LBP) patients as well as the correlation between spinal stability and these angles. Objectives: To investigate the biomechanics of the lumbosacral spine region in acute and chronic LBP patients, as well as to examine the correlation between spinal stability and lumbosacral angles. Study Design: Randomized controlled evaluation Setting: Physical Medicine and Rehabilitation outpatient clinic Methods: Sixty participants with LBP were recruited and categorized as either acute LBP (pain < 3 months) or chronic LBP (pain > 6 months), with 30 subjects in each group. All subjects underwent standing, lateral lumbosacral x-rays, which were analyzed for lumbar stability, SIA, LSA, SHA, lumbar lordosis angle and segmental lumbar lordosis angles. Results: The mean age of the ALBP subjects was 41.00 ± 11.63 (18 – 66) and that of the chronic LBP subjects 49.26 ± 15.6 (22-74), with females comprising 50% of the acute LBP group and 73.3% of the chronic LBP group. Lumbar stability was observed in 62.1% of acute LBP patients and 36.8% of chronic LBP patients. A statistically significant difference was found between the 2 groups in terms of age, gender, and lumbar stability. There was no statistical difference regarding SIA, LSA, SHA, total and segmental lordosis angles between acute and chronic LBP patients (p>0.05). Conclusion: We were unable to find a difference between the radiological values for the shape of the SIA, LSA, SHA, and total and segmental lordosis as noted on screening x-ray techniques regarding the occurrence of acute or chronic LBP, but a statistically significant difference was found for lumbar stability. Further extensive studies are needed to examine lumbar stability and its relationship between angles of lumbosacral region.

Abstract:

Two cats were diagnosed with depression of caudal equina spinal nerve and lumbosacral spinal trauma that revealed rapid improving clinical signs after 1 month of dorsal laminectomy at the region of lumbar and sacral vertebrae without internal and external stabilization devices. This report showed that dorsal laminectomy was a powerful procedure for decompression caudal equina spinal injuries in stable lumbosacral vertebral trauma in cats without ancillary fixation methods. Dorsal laminectomy is valuable technique for correction of fracture/luxation of vertebrae that this procedure can reduce spinal cord edema, and axonal disruption. Stabilization of vertebrae by the orthopedic implants may be not necessary in small cat that has enough vertebral stability as the same in two these cases.

Abstract:

We present a case of a 46-year old woman with a ventral epidural angiolipoma at the lumbosacral level with erosion of the sacrum. About ninety cases of spinal angiolipomas have been previously described in the literature, most of them situated on the thoracic region, dorsal to the dural sac. Angiolipomas can be radically excised with a good prognosis even in the presence of bone erosion. We did not find any other angiolipoma at the sacral level surgically explored in the review of the literature.

Abstract:

Discogenic lumbosacral radiculopathy (DLSR) accounts for up to 5% of all cases of pain in the lumbosacral region, representing one of the most common causes of disability in the population. The issues of pathogenesis, risk factors, course, diagnosis, treatment and prevention of DLSR are discussed. It is noted that in the pathogenesis of DLSR, in addition to compression-ischemic lesions of the spinal root, an important role is played by local inflammatory and autoimmune reactions, which underlie the natural decrease in disc herniation over time. The diagnosis of DLSR is established on the basis of signs of damage to the lumbar and first sacral roots and the absence of signs that are alarming regarding the specific causes of back pain. Magnetic resonance imaging (MRI) of the lumbosacral region allows you to exclude specific causes, identify a herniated disc, but its implementation does not improve the prognosis of the disease if there are no signs of a specific disease. Of great importance is informing the patient with acute DLSR about the favorable course of the disease, the possibility of natural (without surgical intervention) regression of the herniated disc and the associated inflammatory changes. Non-drug (therapeutic gymnastics, manual therapy) and drugs (nonsteroidal anti-inflammatory drugs (NSAIDs), antiepileptic drugs, epidural administration of corticosteroids) in acute DLSR are analyzed. Own experience of management of patients with acute DLSR using meloxicam as an NSAID is presented. It is noted that in the prevention of low back pain, the avoidance of excessive physical and static stress, regular exercises in therapeutic gymnastics, swimming, walking are of leading importance.

✓ The authors report the case of a metastatic juvenile pilocytic astrocytoma of the hypothalamic region in a 10-year-old boy. Eight years after craniotomy and radiation therapy, the tumor spread via cerebrospinal fluid pathways to the left cerebellar tonsil and the lumbosacral region. Histological evaluation of both the original hypothalamic and the new lumbosacral masses showed features of a slow-growing juvenile pilocytic astrocytoma with no evidence of malignant transformation. The clinical implications and possible mechanisms of metastatic spread are discussed.

Abstract:

We have used Hoxd10 expression as a primary marker of the lumbosacral region to examine the early programming of regional characteristics within the posterior spinal cord of the chick embryo. Hoxd10 is uniquely expressed at a high level in the lumbosacral cord, from the earliest stages of motor column formation through stages of motoneuron axon outgrowth. To define the time period when this gene pattern is determined, we assessed Hoxd10 expression after transposition of lumbosacral and thoracic segments at early neural tube stages. We present evidence that there is an early prepattern for Hoxd10 expression in the lumbosacral neural tube; a prepattern that is established at or before stages of neural tube closure. Cells within more posterior lumbosacral segments have a greater ability to develop high level Hoxd10 expression than the most anterior lumbosacral segments or thoracic segments. During subsequent neural tube stages, this prepattern is amplified and stabilized by environmental signals such that all lumbosacral segments acquire the ability to develop high levels of Hoxd10, independent of their axial environment. Results from experiments in which posterior neural segments and/or paraxial mesoderm segments were placed at different axial levels suggest that signals setting Hoxd10 expression form a decreasing posterior-to-anterior gradient. Our experiments do not, however, implicate adjacent paraxial mesoderm as the only source of graded signals. We suggest, instead, that signals from more posterior embryonic regions influence Hoxd10 expression after the early establishment of a regional prepattern. Concurrent analyses of patterns of LIM proteins and motor column organization after experimental surgeries suggest that the programming of these characteristics follows similar rules.

Abstract:

1. We used an isolated preparation of the embryonic chick brain stem and spinal cord to examine the origin, trajectory, and effects of descending supraspinal pathways on lumbosacral motor activity. The in vitro preparation remained viable for < or 24 h and was sufficiently stable for electrophysiological, pharmacological, and neuroanatomic examination. In this preparation, as in the isolated spinal cord, spontaneous episodes of both forelimb and hindlimb motor activity occur in the absence of phasic afferent input. Motor activity can also be evoked by brain stem electrical stimulation or modulated by the introduction of neurochemicals to the independently perfused brain stem. 2. At embryonic day (E)6, lumbosacral motor activity could be evoked by brain stem electrical stimulation. At E5, neither brain stem nor spinal cord stimulation evoked activity in the lumbosacral spinal cord, although motoneurons did express spontaneous activity. 3. Lesion and electrophysiological studies indicated that axons traveling in the ventral cord mediated the activation of lumbosacral networks by brain stem stimulation. 4. Partition of the preparation into three separately perfused baths, using a zero-Ca2+ middle bath that encompassed the cervical spinal cord, demonstrated that the brain stem activation of spinal networks could be mediated by long-axoned pathways connecting the brain stem and lumbosacral spinal cord. 5. Using retrograde tracing from the spinal cord combined with brain stem stimulation, we found that the brain stem regions from which spinal activity could be evoked lie in the embryonic reticular formation close to neurons that send long descending axons to the lumbosacral spinal cord. The cells giving rise to these descending pathways are found in the ventral pontine and medullary reticular formation, a region that is the source of reticulospinal neurons important for motor activity in adult vertebrates. 6. Electrical recordings from this region revealed that the activity of some brain stem neurons was synchronized with the electrical activity of lumbosacral motoneurons during evoked or spontaneous episodes of rhythmic motor activity. 7. Both brain stem and spinal cord activity could be modulated by selective application of the glutamate agonist N-methyl-D-aspartate to the brain stem, supporting the existence of functionally active descending projections from the brain stem to the spinal cord. It is not yet clear what role the brain stem activity carried by these pathways has in the genesis and development of spinal cord motor activity.

Abstract:

Background and Study Aims A great number of unsuccessful intervertebral herniated disk surgeries in the lumbosacral region have highlighted the importance of a comprehensive knowledge of the different types of nerve root anomalies. That knowledge gained by anatomical studies (and intraoperative findings) might contribute to better results. In our study we focused on intraspinal extradural lumbosacral nerve root anomalies and their possible role in radiculopathy. Material and Methods The study was performed on 43 cadavers within 24 hours after death (32 men and 11 women). Bodies were dissected in the prone position, and a laminectomy exposed the entire spinal canal for the bilateral examination of each spinal nerve root from its origin to its exit through the intervertebral foramen or sacral hiatus. Uncommon extradural features in the lumbosacral region were pursued and documented. The spinal dural sac was also opened, aimed at recognizing the normotyped, prefixed, or postfixed type of plexus. Results A total of 20.93% of anomalies of extradural lumbosacral nerve root origins were observed, with the normotyped plexus prevailing. We observed atypical spacing of exits of lumbosacral roots (four cases), two roots leaving one intervertebral foramen (one case), extradural anastomoses (two cases), and missing extradural nerve root courses (two cases). The results were differentiated according to the normotyped, prefixed, or postfixed plexus type. Conclusion Results of similar studies dealing with anomalies of lumbosacral nerve roots were aimed at improving the results of herniated disk surgeries because ∼ 10% of misdiagnoses are related to ignorance of anatomical variability. Our observations may help explain the differences between the clinical picture and generally accepted anatomical standards.

Abstract:

Background: The superior gluteal artery (SGA) passes in between branches of the lumbosacral plexus after arising from the internal iliac artery. Variations in the course of SGA from the internal iliac artery till it passes out of the pelvis through the greater sciatic foramen are very important during pelvic surgeries. Pseudoaneurysm of SGA caused by iatrogenic injuries can compress branches of the lumbosacral plexus, causing foot drops and sciatica. Aims and Objectives: The aim is to study the course of the SGA in relation to branches of the lumbosacral plexus. Materials and Methods: A cross-sectional observational study was done on 25 formalin-fixed human adult cadavers. Dissections were performed in the pelvic region and branches of the internal iliac artery and lumbosacral plexus were identified. SGA was traced on both sides from origin till passing out of the greater sciatic foramen and its relation to branches of lumbosacral plexus was recorded. Results: Three types of pathways taken by SGA were identified in relation to the lumbosacral plexus. The most common path taken by the SGA was between the lumbosacral trunk (LST) and the first sacral nerve. Thirty-five out of 50 were of this type (70%). Ten out of 50 had the second most common type which was between L4 and L5 branches of LST (20%). Five cadavers had SGA lateral to LST (10%). Ten cadavers out of 25 (40%) had side differences in the type of course taken by SGA in relation to the lumbosacral plexus. Conclusion: A surgeon must keep in mind variations in the path taken by SGA in relation to the lumbosacral plexus to prevent pseudoaneurysms of SGA, which in turn can compress branches of lumbosacral plexus, causing foot drop and sciatica.

The presente report describes the macrosopic and radiologic findings of this abnormality in a newborn mongrel dog that was the only one in a litter of six puppies to show changes consistent with spina bifida. The animal presented a cleft at at the dorsal region of the lumbosacral área, resulting in exposure and protrusion of the spinal cord. Plain radiographs of the ventral-dorsal projection of the lumbosacral column revealed a defect in the fusion of the dorsal spinous processes of the lumbosacral vertebrae (L1 – S3), while xyphosis of the entire lumbar region of the spine was seen in the right-lateral radiography. Unfortunately, we still do not know an effective treatment for this kind of case, and there are a few studies on embryonic development focused on prevention and treatment of these anomalies. These surveys are necessary to ensure a good prognosis for patients with this genetic abnormality.

Abstract:

The lumbosacral region of the spine is most susceptible to pathology in large breed dogs. The most common pathologies of this segment include intervertebral disk discopathy, distortion of vertebral vertebrae, narrowing of the lumbosacral canal and congenital defects of the spine. This area is most commonly affected by physical trauma or aging-related conditions leading to a wide range of symptoms, such as pain and loss of mobility.

Abstract:

Objectives: Occult spinal dysraphism is a congenital failure of fusion of the posterior vertebral arches with intact skin overlying the defect. Lumbosacral cutaneous manifestations are associated with a variable risk of occult spinal dysraphism. Tethered cord syndrome is a type of occult spinal dysraphism that puts abnormal traction on the spinal cord. This study analyzed neonates and infants who were referred to our pediatric urology practice and had evidence of lumbosacral cutaneous manifestation on physical examination. Methods: We reviewed the presence of lumbosacral cutaneous manifestations in neonates and infants evaluated in our pediatric urology clinic at our Institution over a 6-year period (1 March, 2015–28 February, 2021) with no prior diagnosis of lumbosacral cutaneous manifestation. All patients underwent a spinal ultrasound. Results: The most common lumbosacral cutaneous manifestations were bifurcated/duplicated gluteal folds (33%), gluteal asymmetry (19%), and sacral dimples (14%). A total of 34 (24%) patients had an abnormal spinal ultrasound; 15 (44%) of these infants underwent a lumbar magnetic resonance imaging. A coccygeal pit was statistically marginally higher in abnormal versus normal spinal ultrasound (p = 0.07). Patients with only one lumbosacral cutaneous manifestation (N = 121) were significantly more likely to have a normal spinal ultrasound compared to those with two or more lumbosacral cutaneous manifestation (N = 17) (79% vs 53%, p = 0.03). Conclusion: Due to the varying risk of certain lumbosacral cutaneous manifestations with occult spinal dysraphism, all patients with a lumbosacral cutaneous manifestation should undergo spinal ultrasound. This study also highlights the importance of urodynamic studies when there are abnormal cutaneous findings. Routine physical examinations of the lumbar region for cutaneous manifestations of occult spinal dysraphism are vital to ensure prompt management of tethered cord syndrome and avoid potentially devastating consequences.

Abstract:

Degenerative lumbosacral stenosis is a common cause of lumbosacral disease in dogs of medium to large breeds. However, decompressive surgery is considered the primary technique for reducing cauda equina and nerve root compression in dogs with degenerative lumbosacral stenosis. The study of the dynamics of the erythrocyte component remains the main indicator of control over the postoperative period during surgical interventions in dogs and deserves their careful analysis. The aim of this study was to evaluate changes in the structural characteristics of erythrocytes during the postoperative period. In this article, an assessment was made of changes in hematological parameters and erythrocyte morphology during the postoperative period. Conducting surgical neurological intervention in the lumbosacral region, with strict observance of aseptic and antiseptic requirements and precise implementation of the method of surgical access and reception, ensures the physiological functioning of the erythrocyte link without causing destructive processes during the postoperative period and the presented surgical method can serve as the basis for performing neurological surgical interventions.

Abstract:

In the structure of occupational pathology, female workers of modern agricultural production, along with diseases of the musculoskeletal system and soft tissues of the upper extremities, vertebrogenic lesions of the lumbosacral level have become more often diagnosed. The aim of the study was to study the features of vertebrogenic pathology of the lumbosacral region with the analysis of radiological and electroneuromyographic data in machine milking operators of the Republic of Bashkortostan. The following results were obtained. On radiographs of the lumbosacral spine, degenerative-dystrophic changes in the form of a decrease in the height of discs, spondylosis, spondyloarthrosis were noted in machine milking operators. Electroneuromyographic criteria revealed a decrease in amplitude and velocity parameters of conduction along the peripheral nerves of the lower extremities. The revealed changes in vertebrogenic lumbosacral pathology in the examined patients make it possible to ensure timely diagnosis and prevention of production-related pathology with the formation of rational schemes of therapeutic and recreational measures.

Abstract:

The effect of acute and chronic section of the digital nerves of a single toe on the organization of low-threshold, mechanoreceptive fields of lumbosacral spinocervical tract (SCT) neurons has been studied in adult cats anesthetized with chloralose. The immediate effect of sectioning the digital nerves of a single toe is to produce a patch of dorsal horn in the medial region of the ipsilateral lumbosacral cord in which SCT neurons lack any peripheral receptive field when gentle hair movement or light touch of glabrous skin are used as stimuli. Other SCT neurons in the region may lose only part of their receptive fields. Between 30 and 70 days later most of the affected SCT neurons have established receptive fields. These are mainly on somatotopically inappropriate areas of skin medially and laterally adjacent to the denervated region. A small proportion of SCT neurons form discontinuous receptive fields. The relative somatotopic organization within the affected region remains unchanged. As there is no sign of regeneration of the sectioned nerves the new receptive fields must result from a central reorganization of excitatory inputs to SCT neurons. It is concluded that chronic peripheral nerve section affects the anatomical and physiological mechanisms underlying the formation of light touch receptive fields of dorsal horn neurons in the lumbosacral cord of the adult cat, but that the resulting reorganization of receptive fields is spatially restricted.

SummaryObjectives: The primary objective was to determine the prevalence, spinal distribution, and association with the signalment of cats suffering from different grades of feline spondylosis deformans (spondylosis). The secondary objective was to document behavioural changes associated with spondylosis by owner observation.Methods: A cross-sectional study was performed to determine the prevalence of feline spondylosis (group 1). A prospective study was performed to determine the association between radiographic abnormalities of the lumbosacral region (L3-S1) and owner perceived behavioural changes based on a completed questionnaire (group 2). The radiographs were reviewed using a grading system (0–3) for spondylosis.Results: The prevalence of spondylosis in group 1 was 39.4% (158/402). Cats with spondylosis were significantly older than cats without spondylosis (p <0.001). The thoracic (T) vertebrae T4-T10 were most often affected by spondylosis, but spondylosis was most severe in the T10-S1 vertebrae. In group 2, spondylosis of the lumbosacral region was significantly correlated with owner-reported behavioural changes, such as a decreased willingness to greet people and to being petted, increased aggressiveness, and a poor perceived quality of life (p = 0.037).Clinical significance: This study found that feline spondylosis is common and that spondylosis of the lumbosacral region may be accompanied by behavioural changes.

Abstract:

Purpose: The study aims to evaluate the effect of kinesiotape methodology on chronic pain syndrome in the lumbosacral region. Material and Methods: 42 participants with chronic low back pain were recruited and randomly divided into two groups – control (n=19) and experimental (n=23). Foreword and lateral tilt, Borg and Modified Merld’Aubigne Scale for pain were used for assessment before and after treatment. Roland-Morris Questionnaire was done to assess the quality of life before and three months after treatment. The participants received a specialized kinesitherapy program combined with kinesio tape daily for 15 days with a duration of 40 minutes per procedure. They all received a home kinesitherapy program. Data were analyzed using GraphPad prism 3.02. Results: 42 participants, including 20 women and 22 men, were examined. The mean age (X±SD) of the control group was 45±9.08years, and for experimental was49.13±8.3 years. Median values of the Borg pain scale were as follows: 7.53±0.84 before, and 6.05±0.78 after treatment for the control group and 7.39±0.99 and 4.61±0.78 for the experimental group. Merld’AubigneScaleshows before and after treatment for control group 4.26±065 and 3.12±0.49 respectively, while in experimental was 4.26±0.68 and 2.09±0.44 after treatment. The average of forwarding tilts measured before and after treatment was13.79±3.77cm and 10±3.6cm for the control group and 13.13±3.76 and 7.52±2.25 for the experimental group. Initially, the quality of life questionnaire shows 17.26±1.66 and three months later was 12±1.45 for the control group and 17.35±1.5 before, and descend to 9.00±1.04 for the experimental group. There were statistically significant differences before and after treatment (p <0.05). Conclusions: Treatment significantly reduces pain and muscle spasms after application and improves thefunctionality of the lumbar spine. Kinesiotape not only helps the reduction of pain symptoms in musculoskeletal pathologies but is also a valuable addition to the kinesitherapy procedures.

Abstract:

The vertebral endplate forms a structural boundary between intervertebral disc and the trabecular bone of the vertebral body. As a mechanical interface between the stiff bone and resilient disc, the endplate is the weakest portion of the vertebral-disc complex and is predisposed to mechanical failure. However, the literature concerning the bone mineral density (BMD) distribution within the spinal endplate is comparatively sparse. The objective of this study is to investigate the three-dimensional (3D) distribution of computed tomography (CT) attenuation across the lumbosacral endplate measured in Hounsfield Units (HU). A total of 308 endplates from 28 cadaveric fresh-frozen lumbosacral spines were used in this study. Each spine was CT-scanned and the resulting DICOM data was used to obtain HU values of the bone endplate. Each individual endplate surface was subdivided into five clinically-relevant topographic zones. Attenuation was analyzed by spinal levels, sites (superior or inferior endplate) and endplate region. The highest HU values were found at the S1 endplate. Comparisons between the superior and inferior endplates showed the HU values in inferior endplates were significantly higher than those in the superior endplates within the same vertebra and the HU values in endplates cranial to the disc were significantly higher than those in the endplates caudal to the disc within the same disc. Attenuation in the peripheral region was significantly higher than in the central region by 32.5%. Regional comparison within the peripheral region showed the HU values in the posterior region were significantly higher than those in the anterior region and the HU values in the left region were significantly higher than those in the right region. This study provided detailed data on the regional HU distribution across the lumbosacral endplate, which can be useful to understand causes of some endplate lesions, such as fracture, and also to design interbody instrumentation.

Abstract:

Introduction: Lumbosacral transitional abnormalities are fairly common birth defects in the general population, with a high prevalence in low back pain patients. The objective was to study the detailed epidemiological and CT aspects of lumbosacral transitional anomalies. Materials and Method: This was a retrospective cross-sectional study carried out in the Medical Imaging Department of Professor Bocar Sidy SALL University Hospital in Kati over a period of one year (01 July 2021 to 30 June 2022). A siemens somatom emotion scanner of 16 bars was used for the examinations. We used the castellvi classification to classify the different anomalies. Results: At the end of our study we collected 80 patients with lumbosacral transitional abnormality on 623 lumbar CT performed, a frequency of 12.84%. Lumbosciatica was the first reason for consultation (50%), the average age of our patients was 47 years and the 40-65 age group was in the majority (48.75%) with a male predominance (51%). Sacralization was the most frequent type of transitional anomaly (70%), with a predominance of type IIb, low back accounting for 30% with a predominance of type IIb. The combination of degenerative disc disease, lumbosacral and sacroiliac osteoarthritis was present in 75% of cases, bertolotti syndrome was found in 52.5%. Conclusion: Lumbosacral transitional abnormalities are common in our region. The scanner allowed us a detailed semiological study of these abnormalities of the lumbosacral hinge. Castelvi's type IIb was the most common.

Abstract:

The meningeal arrangement of the lumbosacral cord of Gallus is comparable to that of mammals. The meninges are formed by three lamellae: inner, intermediate, and outer. The arachnoid space, between the outer and intermediate lamellae, is wide and filled with a trabecular network, except in the region of the glycogen body and lobes of Lachi. This region is invaded by the glycogen body cells which also disrupt the inner and intermediate lamellae. A similarity between this region and the cerebellomedullary cistern of mammals is postulated, and the meaning of the presence of glycogen in the outer cerebrospinal fluid compartment is also discussed.

Abstract:

Vertebrogenic lumbosacral radiculopathy, being a global problem of modern healthcare, occupies one of the leading places among the reasons for visiting doctors of various specialties and disability of people of different age categories. According to modern scientific medical research by a number of authors, an episode of back pain, at least once in a lifetime, is noted by 100% of the able-bodied population of developed countries. The high urgency of the problem of degenerative changes in the spine in the lumbar region is determined by neurological manifestations, changes in psychological and personal characteristics, and a decrease in the quality of life, which attracts close attention of the scientific and medical communities. In particular, it is associated with the peculiarities of the course of the disease, the high frequency of exacerbations and the occurrence in people of the most able-bodied age, unsatisfactory results of treatment and rehabilitation measures, the transformation of the pain syndrome into a chronic form and progressive disability. According to the literature, from 60% to 80% of the population in industrialized countries experience pain of varying intensity in the lower back against the background of dorsopathy, whose share in the formation of neurological syndromes reaches 95%, and pain, including discogenic origin, is considered the most obligate symptom. , occurring in every fifth person over 30 years of age. In the development and progression of dorsopathies, a significant role is given to the disruption of microcirculation processes, which are observed at the stage of clinically developed manifestations both locally - at the level of the affected segment, becoming one of the factors causing acute pain syndrome, and systemically - in the reflex zones and the central nervous system (CNS) , leading to the preservation, deterioration and chronicity of pain in the conditions of transformation of tissue homeostasis, sensitization and functional dissonance of the CNS structures at different levels, determining the formation of negative pain experience and negative psycho-emotional reactions. A large number of authors indicate degenerative lesions and changes in the musculoskeletal apparatus of the spinal column as the main causes of pain in dorsopathy.

Abstract:

Object The authors describe their experience in a series of cases of intraneural ganglia within the hip and pelvic regions, and explain the mechanism of formation and propagation of this pathological entity. Methods Five patients with 6 intraneural ganglia are presented. Four patients presented with symptomatic intraneural ganglia in the buttock and pelvis affecting the sciatic and lumbosacral plexus elements. An asymptomatic cyst affecting the opposite sciatic nerve was found on MR imaging in 1 patient. The fifth patient, previously reported on by another group, had an obturator intraneural ganglion that the authors reinterpreted. Results All 5 intraneural ganglia affecting the sciatic and lumbosacral plexus elements were found to have a joint connection to the posteromedial aspect of the hip joint; the obturator intraneural cyst had a joint connection to the anteromedial aspect of the hip joint. In all cases, initial review of the MR images led to their misinterpretation. Conclusions To the authors' knowledge, these are the first cases of intraneural ganglia demonstrated to have a connection to the hip joint. This finding at a rare site provides further evidence for the unifying articular (synovial) theory for the formation of intraneural ganglia and reveals a shared mechanism for their propagation. Furthermore, understanding the pathogenesis of these lesions provides insight into their successful treatment and their recurrence.

Abstract:

AbstractOccult spinal dysraphism with spinal lipoma, is a rare congenital spinal dysraphic anomaly which usually involves lumbosacral region and manifests in childhood. In the present article, we discuss a case of a 26-year-old man who developed sudden low back pain following intercourse. Magnetic resonance imaging of the lumbosacral spine was suggestive of spina bifida occulta with hemorrhage. The patient underwent a L4–5 laminectomy in the emergency. There was the presence of altered blood in the vicinity of the lesion suggestive of recent hemorrhage. Histopathological examination of the lesion was suggestive of the lipoma. In the present case, the patient had occult spina bifida due to lumbosacral lipoma leading to the tethering of the dura. Strenuous activity resulted in overstretching of the tethered structures and subsequent hemorrhage and intense low back pain which responded well to the surgical treatment.
