Asymmetry of paraspinal muscles on the convex and concave sides in adults with degenerative scoliosis and its correlation with vertebral bone quality score
摘要
Abstract
Objective To analyze the asymmetry of the anterior and posterior tension bands on the convex and concave sides of the paraspinal muscles in patients with adult degenerative scoliosis and its correlation with skeletal parameters,aiming to provide a reference for comprehensive preoperative clinical evaluation in ADS patients.Methods A total of 69 ADS patients who visited the Second Affiliated Hospital of Kunming Medical University from January 2023 to January 2025 were collected.These patients underwent full-spine X-ray and MRI examinations.Coronal parameters recorded from standing full-spine X-rays included apical vertebral translation(AVT),Cobb angle(CA),and coronal balance distance(CBD).Sagittal parameters included sagittal vertical axis(SVA)and lumbar lordosis(LL).At the level of the central vertebral body on lumbar MRI,the following measurements were obtained:the lumbar cross-sectional area(LCSA)of the apical vertebral body,the cross-sectional area(CSA)of the anterior and posterior tension bands on the convex and concave sides,the ratio of CSA to LCSA represents the relative cross-sectional area,the fat infiltration(FI)of the anterior and posterior tension bands on the convex and concave sides,and the average signal intensity of the L1-4 vertebral bodies and the cerebrospinal fluid posterior to the L3 vertebral body on sagittal T1-weighted MRI,which were used to calculate the vertebral bone quality(VBQ)score.Based on the absolute value of the CBD,patients were divided into three groups:Group A(balanced,CBD<20 mm,40 cases),Group B(concave-side deviation,CBD≥20 mm,17 cases),and Group C(convex-side deviation,CBD≥20 mm,12 cases).Results In 69 ADS patients,the relative CSA and FI of the posterior tension band on the concave side at the level of the central vertebral body were significantly greater than those on the convex side(P<0.05).No statistically significant differences were observed in the relative CSA and FI of the anterior tension band on the convex and concave sides(P>0.05).The VBQ score showed a mild positive correlation with the FI of the anterior tension band on the convex and concave sides(r=0.312,0.246,P<0.05)and a significant positive correlation with the FI of the posterior tension band on the convex and concave sides(r=0.690,0.866,P<0.05).Conclusion Asymmetry in the relative CSA and FI of the anterior and posterior tension bands on the convex and concave sides of the paraspinal muscles is observed in ADS patients,with the concave side being more pronounced than the convex side.The FI of the anterior and posterior tension bands on the convex and concave sides is significantly correlated with the VBQ score.关键词
