Methods The novel Cobb protractor had two endplate markers. A measurement was performed just to align the two markers to each endplate of the curve. The Cobb angle on the posteroanterior radiographs of 24 patients clinically diagnosed with adolescent idiopathic scoliosis was measured by three orthopedic surgeons with both standard Cobb method and the new technique, and the time of measurement was recorded. Intraclass correlation coefficients(ICCs) were calculated to assess the reliability of the new method. Results The time for a measurement with the new tool was approximately 10 seconds less than the time that used to finish a measurement with the standard method(P<0.05). The overall mean Cobb angle for the major curve of the 24 patients was 47.8°. The mean overall intraobserver and interobserver ICC was 0.971 and 0.971 for the Cobb method group, while the overall intraobserver ICC and the interobserver was 0.985 and 0.979 for the new tool group. Conclusions The novel Cobb protractor could perform quick measurement and measure almost all forms of radiographs. The Cobb protractor might be an ideal instrument to measure the Cobb angle. 展开更多

BACKGROUND Thoracic scoliosis causes complex three-dimensional deformities of the thoracic cage that can impair lung mechanics and airway geometry,leading to restrictive ventilatory dysfunction.Respiratory impairment differs by etiology,with nonidiopathic scoliosis often showing more severe and persistent deformity.Conventional pulmonary function testing provides global functional assessment but is frequently limited in patients with non-idiopathic scoliosis.Advances in chest computed tomography(CT)allow quantitative evaluation of lung volume and airway morphology,offering an alternative approach to assess respiratory function and the relationship to spinal deformity.AIM To investigate CT-derived airway morphology and respiratory function in thoracic scoliosis,focusing on etiologic differences and structure-function relationships.METHODS This retrospective observational study included 53 patients≤30 years of age who underwent corrective surgery for thoracic scoliosis and had preoperative and postoperative CT examinations.Patients were classified into idiopathic(n=25)or non-idiopathic scoliosis(n=28).Spinal deformity parameters,lung volumes,predicted total lung capacity percentage(TLC%),and airway dimensions were quantified using CT.Group comparisons were performed using the Wilcoxon rank-sum test,correlations were determined using Spearman’s rank correlation,and pre-and postoperative changes were determined using the Wilcoxon signed-rank test.RESULTS Patients with non-idiopathic scoliosis had significantly more severe spinal deformities and a lower TLC%compared to patients with idiopathic scoliosis(median TLC%:39%vs 64%,P<0.001).The Cobb angle was negatively correlated with TLC%(ρ=-0.52,P=0.004),lung volumes,and multiple airway parameters in patients with non-idiopathic scoliosis.Surgical correction significantly improved spinal alignment in both groups.CTderived lung volume parameters did not show significant postoperative changes.In contrast,selective improvement was observed in the left bronchus.CONCLUSION CT-derived analysis showed differences in respiratory impairment between idiopathic and non-idiopathic scoliosis.Surgical correction improved alignment without immediate lung volume improvement,with selective changes in the left bronchus. 展开更多

The surgical treatment of severe scoliosis and kyphoscoliosis in the pediatric population is complicated and has high morbidity and mortality risks.Severe scoliosis has traditionally been defined by a coronal Cobb angle of greater than 90°or 100°.The usual corrective methods for these patients have been anterior or posterior release and osteotomies using a combined anterior-posterior or posterior-only approach.Many of these patients have pre-existing pulmonary compromise;therefore,an anterior approach is often not reasonable or possible.Acute correction of a deformity may also cause neurologic injury.Halo gravity traction(HGT)allows for progressive,gradual,and sustained correction of the spinal deformity in the coronal,sagittal,and axial planes,leading to a decrease in the amount of correction needed at definitive posterior fusion.This relates to decreased postoperative neurologic deficit and improved pulmonary function.Preoperative HGT has evolved to be the surgical adjunct in the treatment of severe spinal deformity.Indications for HGT,best protocols of application,and optimal duration of traction still lack uniformity;thus,a review of the literature remains relevant and necessary.This review summarizes the existing literature on HGT,including its indications,applications,duration of traction,and associated complications. 展开更多

OBJECTIVE:To investigate the effect of spinal manipulation(SM)on degenerative scoliosis by evaluating patients’visual analog scale(VAS)scores,Cobb angles,sagittal vertical axis(SVA),and apical vertebral rotation(AVR)and to explore factors that influence treatment effect.METHODS:A total of 55 patients with degenerative scoliosis received 4 weeks of SM.After treatment,patients were divided into two groups:the remission group(VAS score<40 mm)and the non-remission group(VAS score≥40 mm).Pre-versus post-treatment VAS scores,Cobb angles,SVA,and AVR were compared in each group and in the total population.Baseline data(sex,age,symptom characteristics,duration of symptoms,VAS score,Cobb angle,SVA,and AVR)were compared between groups.Factors influencing the post-treatment VAS score were explored with multiple linear regression analysis.RESULTS:No changes were found in the Cobb angle(P=0.722)or AVR(P=0.424)after intervention in the overall population.However,the SVA(P<0.001)and VAS score(P=0.000)changed significantly after treatment.Similar changes were observed in the remission group(n=29).Multiple linear regression revealed that the only factors influencing treatment effect were symptom characteristics,SVA,and VAS score.CONCLUSION:SM relieved pain and improved sagittal imbalance in patients with degenerative scoliosis.It did not lessen the severity of coronal curvature or vertebral rotation.Factors influencing the effect of SM included symptom characteristics,VAS score,and SVA.A larger randomized trial is needed to further confirm our results. 展开更多

AIM To find accompanying anomalies of typical and atypical Scheuermann's disease(SD) is reported in the present study. METHODS Study included 20 patients(16 men and 4 women) who had radiological imaging radiography, magnetic resonance imaging(MRI) and computed tomography, if available, due to back pain, curved back and low back pain in November 2011-February 2016 period. Patients were categorized into typical and atypical patterns based on the region involved. Thoracic kyphosis values were measured using real Cobb angle. Accompanying disc degeneration, herniations and spinal cord pathologies were studied using MRI.RESULTS Age of the patients ranged from 11.0 to 23.0(mean 17.2 ± 3.0). Typical pattern of SD were detected in 15 patients while atypical pattern were detected in 5 patients. Cobb angle range was 40.2-67.2(mean 55.5 ± 8.7) in typical Scheuermann's patients and 24.7-49.9(mean 36.7 ± 10.8) in atypical ones. Intervertebral level was affected and had the measures of 3-8(mean 5.3 ± 1.6) and 7-9(mean 8.2 ± 0.8) in typical and atypical Scheuermann's patients, respectively. Level of degenerative disc disease in MRI was 1-7 discs(mean 4.1 ± 1.7) in typical patients and 5-10 discs(mean 7.6 ± 1.9) in atypical patients.CONCLUSION SD can be seen in typical and atypical patterns, typical being more frequent. Because degenerative disc diseases,herniations and cord pathologies such as syringomyelia can accompany SD(albeit more common in atypical pattern), it is necessary to evaluate these patients with plain radiography and MRI together. 展开更多
