Objective To investigate the differences of spinal curvature, thoracic sagittal mobility, and respiratory strength between patients with chronic neck pain (CNP) and people without cervical pain, and to determine the correlation between respiratory strength and thoracic mobility in CNP patients.Methods A total of 78 participants were finally included in this study, of whom 30 had no cervical pain and 48 had CNP. The Neck Disability Index (NDI), cervical lordotic curvature, thoracic kyphotic curvature, thoracic sagittal range of motion (ROM), maximal inspiratory pressure (MIP), and maximal expiratory pressure (MEP) were measured and analyzed.Results In males, thoracic sagittal ROM<sub>MEP-MIP</sub> and MEP showed a significant difference between the no cervical pain group and the CNP group. In females, thoracic kyphotic curvature, thoracic sagittal ROM<sub>MEP-MIP</sub>, MIP, and MEP were significantly different between the no cervical pain group and the CNP group. Thoracic kyphotic curvature was significantly correlated with MEP and MIP in all population groups, and significantly correlated with NDI in the female group. Thoracic sagittal ROM<sub>MEP-MIP</sub> had a significant linear relationship with NDI, MEP, and MIP in all population groups.Conclusion The thoracic mobility during forced respiration was reduced in patients with CNP and was correlated with respiratory strength. Changes in the biomechanics of the cervicothoracic spine and rib cage due to CNP may contribute to impairment of respiratory strength.

Introduction. Kyphosis is a deformity of the spine characterized by excessive backward curvature of the thoracic spine. The normal range of thoracic kyphosis in teenagers is 20 - 40 degrees, and the diagnosis of hyper-kyphosis is beyond 45 degrees. The aim of this review was to assess the magnitude of the effects of various corrective exercises on kyphotic angle reduction. Material and Methods. The Web of Science and PubMed were searched to retrieve relevant literature. Ten studies were included in our systematic review and meta-analysis. Results. The magnitude of the effects of corrective exercises on the kyphotic angle correction was estimated and the results showed a statistical significance in standardized mean difference (-0.504, P < 0.001). The analysis of the subgroups regarding the age showed a heterogeneity that was not statistically significant and the magnitude of the effects in different age groups. Conclusion. The results of our meta-analysis may be useful to many physiotherapists and clinicians in solving problems in patients with kyphosis and hyper-kyphosis.

In literature, the development of spinal deformities was reported after surgical intervention for congenital heart disease using thoracotomy and sternotomy incisions in children; however, there are not enough data regarding the incidence of spinal kyphosis after open-heart surgery in adults. This study aimed to determine the impact of open-heart surgery using median sternotomy incision on the sagittal plane thoracic spine curve and pulmonary functions after open-heart surgery. A cross- sectional study was conducted on 100 participants (53 ± 9.43 years), who underwent open heart surgery using median sternotomy. The spinal kyphotic curve was evaluated using a Flexicurve ruler and spirometry parameters [forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and ratio of forced expiratory volume in the first second to forced vital capacity (FEV1/FVC)] were evaluated before and one week after open-heart surgery. The comparison between the preoperative and postoperative measurements of the variables under study was performed using the paired t-test. Statistical significance was set at (P ˂ 0.05). The results revealed a significant increase in the dorsal kyphotic curve (9.75 ± 2.32) and a significant decrease in all spirometry parameters under study [(FVC: 2.12 ± .77); (FEV1:1.55 ± .64) and (FEV1/FVC: 0.72 ± .13)] with an alpha level of (P < 0.05). There is a high incidence of exaggerating the sagittal plane thoracic spine curvature (thoracic kyphosis), and reduction in the pulmonary functions after open-heart surgery using median sternotomy incision.

Full textAbstract:
ABSTRACT Tetranectin is a plasminogen-binding, homotrimeric protein belonging to the C-type lectin family of proteins. Tetranectin has been suggested to play a role in tissue remodeling, due to its ability to stimulate plasminogen activation and its expression in developing tissues such as developing bone and muscle. To test the functional role of tetranectin directly, we have generated mice with a targeted disruption of the gene. We report that the tetranectin-deficient mice exhibit kyphosis, a type of spinal deformity characterized by an increased curvature of the thoracic spine. The kyphotic angles were measured on radiographs. In 6-month-old normal mice (n= 27), the thoracic angle was 73° ± 2°, while in tetranectin-deficient 6-month-old mice (n = 35), it was 93° ± 2° (P < 0.0001). In approximately one-third of the mutant mice, X-ray analysis revealed structural changes in the morphology of the vertebrae. Histological analysis of the spines of these mice revealed an apparently asymmetric development of the growth plate and of the intervertebral disks of the vertebrae. In the most advanced cases, the growth plates appeared disorganized and irregular, with the disk material protruding through the growth plate. Tetranectin-null mice had a normal peak bone mass density and were not more susceptible to ovariectomy-induced osteoporosis than were their littermates as determined by dual-emission X-ray absorptiometry scanning. These results demonstrate that tetranectin plays a role in tissue growth and remodeling. The tetranectin-deficient mouse is the first mouse model that resembles common human kyphotic disorders, which affect up to 8% of the population.

Object The purpose of this study was to determine the efficacy of anterior instrumentation following radical debridement and tibial allografting and its long-term progression in patients with multilevel spinal tuberculosis. Methods This prospective observational study was undertaken to analyze 22 patients with multilevel spinal tuberculosis (Pott disease) who underwent anterior radical debridement, decompression, and fusion using anterior spinal instrumentation and tibial allograft replacement between 1999 and 2001. Clinical outcomes were assessed using the American Spinal Injury Association (ASIA) Impairment Scale and a visual analog scale (VAS). Preoperative and postoperative plain radiographs were obtained, and the focal kyphotic angle of the surgically treated spinal segments and the overall sagittal and coronal contours of the thoracic and lumbar spine were evaluated in all patients. Results The mean follow-up time was 84 months (range 36–96 months). All patients demonstrated clinical healing of the tuberculosis infection. All patients showed evidence of successful bone fusion. The mean late postoperative kyphosis correction was 74% (range 63–91%). On average, 2° (range 0–5°) of loss of correction was noted in the local kyphotic angle postoperatively in late follow-up findings. Evaluation of the surgical effect on sagittal global contours showed a significant correction rate in thoracic, thoracolumbar, and lumbar regions. The mean late postoperative coronal plane alignment correction was 99%. The ASIA Impairment Scale scores demonstrated significant improvement in late follow-up results in our series. Surgical decompression also resulted in a dramatic reduction of overall pain in all patients (late postoperative VAS score 1.61 ± 0.81). Conclusions Anterior tibial allografting and instrumentation provide correction of the curvature, prevention of further deformation, improvement of sagittal and coronal balance, and restoration of neurological function in patients with spinal tuberculosis.

Introduction. Few studies have evaluated the functionaloutcomes of traumatic thoracic and lumbar vertebral bodyfractures. This study evaluated the functional and clinicaloutcomes of patients, who sustained a fracture to thethoracolumbar area of the spine (T10 to L2 region), with≥ 25° kyphosis versus those with less kyphotic curvature.
Methods. The trauma registry records of two level 1 traumacenters using ICD-9 codes for fracture to the thoracolumbarjuncture (T10 to L2 region) were reviewed. Kyphosis anglewas measured on the standing lateral thoracolumbar (T1 -L5) radiograph at initial trauma and at clinical follow-up.Functional outcome questionnaires, including the OswestryDisability Questionnaire (ODQ), the Roland Morris DisabilityQuestionnaire (RMDQ), and the Nottingham Health Profile(NHP), were evaluated at clinical follow-up. Work statusand medication used after trauma also were recorded.
Results. A total of 38 patients met the inclusive criteria. Seventeenpatients (45%) had ≥ 25° kyphosis and 21 patients (55%)had < 25° kyphosis at follow-up. These two groups were similarbased on sex and age. Based on the ODQ Score, the RMDQScore, and the NHP, no statistically significant differenceswere detected between the two groups in regards to energy,pain, mobility, emotional reaction, social isolation, and sleep.
Conclusions. Patients who sustained a fracture to the thoracolumbararea of the spine with ≥ 25° kyphosis do notreport worse clinical outcomes. When using the kyphosisangle as an indication for surgery, it should be used withcaution and not exclusively. KS J Med 2017;10(2):30-34.

Abstract BACKGROUND Previous studies have evaluated cervical kyphosis (C-kypho) using cervical curvature or chin-brow vertical angle, but the relationship between C-kypho and global spinal alignment is currently unknown. OBJECTIVE To elucidate global spinal alignment and compensatory mechanisms in primary symptomatic C-kypho using full-spine radiography. METHODS In this retrospective multicenter study, symptomatic primary C-kypho patients (Cerv group; n = 103) and adult thoracolumbar deformity patients (TL group; n = 119) were compared. We subanalyzed Cerv subgroups according to sagittal vertical axis (SVA) values of C7 (SVAC7 positive or negative [C7P or C7N]). Various Cobb angles (°) and SVAs (mm) were evaluated. RESULTS SVAC7 values were –20.2 and 63.6 mm in the Cerv group and TL group, respectively (P < .0001). Various statistically significant compensatory curvatures were observed in the Cerv group, namely larger lumbar lordosis (LL) and thoracic kyphosis. The C7N group had significantly lower SVACOG (center of gravity of the head) and SVAC7 (32.9 and –49.5 mm) values than the C7P group (115.9 and 45.1 mm). Sagittal curvatures were also different in T4-12, T10-L2, LL4-S, and LL. The value of pelvic incidence (PI)-LL was different (C7N vs C7P; –2.2° vs 9.9°; P < .0003). Compensatory sagittal curvatures were associated with potential for shifting of SVAC7 posteriorly to adjust head position. PI-LL affected these compensatory mechanisms. CONCLUSION Compensation in symptomatic primary C-kypho was via posterior shifting of SVAC7, small T1 slope, and large LL. However, even in C-kypho patients, lumbar degeneration might affect global spinal alignment. Thus, global spinal alignment with cervical kyphosis is characterized as head balanced or trunk balanced.

OBJECTIVEThe goal of this study was to investigate the impact of thoracic and lumbar alignment on cervical alignment in patients with adolescent idiopathic scoliosis (AIS).METHODSEighty-one patients with AIS who had a Cobb angle > 40° and full-length spine radiographs were included. Radiographs were analyzed using dedicated software to measure pelvic parameters (sacral slope [SS], pelvic incidence [PI], pelvic tilt [PT]); regional parameters (C1 slope, C0–C2 angle, chin-brow vertical angle [CBVA], slope of line of sight [SLS], McRae slope, McGregor slope [MGS], C2–7 [cervical lordosis; CL], C2–7 sagittal vertical axis [SVA], C2–T3, C2–T3 SVA, C2–T1 Harrison measurement [C2–T1 Ha], T1 slope, thoracic kyphosis [TK], lumbar lordosis [LL], and PI-LL mismatch); and global parameters (SVA). Patients were stratified by their lumbar alignment into hyperlordotic (LL > 59.7°) and normolordotic (LL 39.3° to 59.7°) groups and also, based on their thoracic alignment, into hypokyphotic (TK < −33.1°) and normokyphotic (TK −33.1° to −54.9°) groups. Finally, they were grouped based on their global alignment into either an anterior-aligned group or a posterior-aligned group.RESULTSThe lumbar hyperlordotic group, in comparison to the normolordotic group, had a significantly larger LL, SS, PI (all p < 0.001), and TK (p = 0.014) and a significantly smaller PI-LL mismatch (p = 0.001). Lumbar lordosis had no influence on local cervical parameters.The thoracic hypokyphotic group had a significantly larger PI-LL mismatch (p < 0.002) and smaller T1 slope (p < 0.001), and was significantly more posteriorly aligned than the normokyphotic group (−15.02 ± 8.04 vs 13.54 ± 6.17 [mean ± SEM], p = 0.006). The patients with hypokyphotic AIS had a kyphotic cervical spine (cervical kyphosis [CK]) (p < 0.001). Furthermore, a posterior-aligned cervical spine in terms of C2–7 SVA (p < 0.006) and C2–T3 SVA (p < 0.001) was observed in the thoracic hypokyphotic group.Comparing patients in terms of global alignment, the posterior-aligned group had a significantly smaller T1 slope (p < 0.001), without any difference in terms of pelvic, lumbar, and thoracic parameters when compared to the anterior-aligned group. The posterior-aligned group also had a CK (−9.20 ± 1.91 vs 5.21 ± 2.95 [mean ± SEM], p < 0.001) and a more posterior-aligned cervical spine, as measured by C2–7 SVA (p = 0.003) and C2–T3 SVA (p < 0.001).CONCLUSIONSAlignment of the cervical spine is closely related to thoracic curvature and global alignment. In patients with AIS, a hypokyphotic thoracic alignment or posterior global alignment was associated with a global cervical kyphosis. Interestingly, upper cervical and cranial parameters were not statistically different in all investigated groups, meaning that the upper cervical spine was not recruited for compensation in order to maintain a horizontal gaze.

Full textAbstract:
Object. In 10 to 50% of cases with neurofibromatosis, skeletal disorders are present, mainly as various deformities of the spine. These deformities can be divided into dystrophic and nondystrophic groups depending on the absence or presence of bone dystrophy. The nondystrophic curves are highly similar to those in idiopathic scoliosis, whereas the dystrophic curves are manifested early and, by progressing inexorably, may lead to neurological symptoms. In this article the authors report on a series of 12 patients (11 with dystrophic and one with nondystrophic deformities) who underwent surgical treatment. Methods. In the case with a nondystrophic curve, posterolateral instrumentation-assisted fusion was performed. A curvature correction of 70% was achieved in the frontal plane, and at the 2-year follow-up examination neither bone dysplasia nor pseudarthrosis was observed. In the cases with dystrophic curves, preoperative traction for 3 weeks was applied; anterior surgical release was then performed, as was two-stage posterior instrumentation-assisted fusion. In the cases of thoracic kyphoscoliosis in which this treatment protocol was performed, the mean scoliosis correction was 66%, whereas the mean decrease in kyphotic angle was 34.5°. In the cases with thoracolumbar and lumbar curves, the mean correction in the frontal plane was 69.8°, whereas the mean preoperative lumbar kyphosis of 42° was corrected to a mean lordotic angle of 23°. Postoperatively, no hook dislocation was detected. A neurological complication was observed in one case. Conclusions. The surgical treatment of dystrophic curves always included 360° fusion and the use of a tibial corticocancellous graft, which must be placed on the concave side of the curve in the frontal plane, the graft thereby providing biomechanical support.

Full textAbstract:
Adolescent idiopathic scoliosis (AIS) is a complex condition characterized by a lateral curvature and axial rotational deformity of the spine. Though bracing is effective, a need remains to identify the effect brace type has on spine curvature. To examine differences in patient demographics between the Boston and Providence brace, determine the corrective change in Cobb angle and RVAD and investigate the effect of brace type on curvature over time. A retrospective chart review was conducted of 105 patients diagnosed with AIS from 2013–2016 at CHW. Five spinal parameters were measured: Cobb angle, Risser, RVAD, kyphosis and lordosis. Data was collected before bracing, in-brace and at 24 months. A final treatment outcome of either Cobb angle correction (reduction >5°), stabilization (change ±5°) or progression (deterioration >5°) was then evaluated. Providence brace provided significantly greater in-brace thoracolumbar Cobb angle and RVAD reduction in comparison to the Boston brace (Cobb angle -21.9° vs. -12.5°; RVAD: -1.8° vs. 1.62°). Similarly, Providence users had a significantly smaller increase in Cobb angle and RVAD over time (Cobb angle: thoracic 14.2° vs. 15.0°; thoracolumbar 23.6° vs. 26.0°; RVAD: 5.2° vs. 8.5°). Ultimately, no significant difference in final treatment outcome was established between brace groups. Although the Providence brace provides less of an increase in thoracic and thoracolumbar curvatures over time, both braces are an effective treatment and achieve comparable outcomes. Selection of braces may vary with primary curve angle, curve location, patient compliance and quality of life.

Full textAbstract:
Neurofibromatosis is often related with severe orthopaedic disorders in children. Bone lesions are rare but pose severe difficulties in management. It affects the spine and long bones. Lesions are associated either from enlargement of neurofibromas that affect the normal growth or from primary neurofibromatosis of long bones. Dystrophic scoliosis appears with short curves, with kyphosis and rotation of the apical vertebrae. Usually affect the thoracic spine, with penciling of the ribs. Surgical treatment is challenging in cases of rapid progression. Scoliosis may appear with curvatures similar to those in idiopathic scoliosis, without dysplastic changes of the vertebrae. Anterior bowing of the tibia is manifestation of NF and is distinguished from the benign posterolateral bowing. Evaluation of the medullary canal and presence of cystic lesions in the tibia is essential. Progression to pseudoarthrosis or pathologic fracture is common. Surgical management of tibial pseudoarthrosis remains a difficult procedure. Pseudoarthrosis may appear in fibula, radius or ulna but are extremely rare. Irregular eccentric bone cysts in long bones that are commonly diagnosed after a pathologic fracture, must be differentiated for NF. Malignant transformation of neurofibromas must be considered when there is rapid progression of the lesion.

Full textAbstract:
In clinical settings, doctors classify pulmonary disorders into two main categories, obstructive lung disease and restrictive lung disease. The former is characterized by the airway obstruction which is associated with several disorders like chronic bronchitis, asthma, bronchiectasis, and emphysema [1]. The latter is caused by different conditions where one of the triggers is tied to the spine deformity. In general, a pulmonary function test (PFT) [2] is used to evaluate and diagnose lung function, and physicians depend on the test results to identify the disease patterns of the patients (obstructive or restrictive lung disease). In the PFT, some parameters including total lung capacity (TLC), vital capacity (VC), and residual volume (RV) can infer the lung volume and lung capacity. Other parameters, such as forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1), are often employed to assess the pulmonary mechanics. Scoliosis is an abnormal lateral curvature of the spine which involves not only the curvature from side to side but also an axial rotation of the vertebrae. Restrictive lung disease often happens in scoliosis patients, especially with severe spine deformity. Spine deformity if left untreated may lead to progression of the spinal curve, respiratory complications, and the reduction of life expectancy due to the decrease in thoracic volume for lung expansion. However, the relationship between thoracic volume and pulmonary function is not broadly discussed, and anatomic abnormalities in spine deformity (ex: scoliosis, kyphosis, and osteoporosis) can affect thoracic volume. Adequate thoracic volume is needed to promote pulmonary function. Previous literature has shown that the deformity of the thoracic rib cage will have detrimental effects on the respiratory function in adolescent idiopathic scoliosis patients [3–4]. In this paper, we aim to correlate thoracic volume and the parameters in PFTs in adult scoliosis patients 25–35 years after receiving treatments during their adolescence, either with physical bracing or spinal fusion surgery.
