成年脊柱畸形患者和无症状受试者脊柱骨盆肌肉体积的比较研究

Comparative study of spinal pelvic muscle volume between adult spinal malformations and asymptomatic subjects

目的探讨成年脊柱畸形患者和无症状受试者脊柱骨盆肌肉体积及其临床意义。方法选取脊柱畸形患者80例,分为有症状组(n=34)和无症状组(n=46)。收集两组一般临床资料、影像学指标和脊柱骨盆肌肉体积,分析患者症状表现与脊柱骨盆肌肉体积的相关性。结果有症状组脊柱骨盆肌肉体积、臀大肌、臀中肌和臀小肌相对横截面积则显著低于无症状组,脂肪浸润则显著高于无症状组(P<0.05)。Person分析显示,患者的症状刀背样畸形、半椎体畸形、腰背部僵硬感、呼吸困难、髋部疼痛以及活动受限与患者的骨盆肌肉体积均存在显著的负相关关系(P<0.05)。结论成年脊柱畸形患者脊柱骨盆肌肉的体积显著低于无症状受试者。

Objective To compare the volume of spinal pelvic muscles between adult patients with spinal deformities and asymptomatic subjects,and to determine its clinical significance.Methods Eighty patients with spinal deformity were selected as study objects.They were divided into a symptomatic group(n=34)and an asymptomatic group(n=46).General clinical data,imaging indicators and spinal pelvic muscle volume of the two groups were collected.The correlation between symptoms and spinal pelvic muscle volume was analyzed.Results The spinal pelvic muscle volume,the relative cross-sectional area of gluteus maximus,gluteus medius and gluteus minor in the symptomatic group were significantly smaller than those in the asymptomatic group,and fat infiltration was significantly larger than that in the asymptomatic group(P<0.05).Person analysis showed that the patient's symptoms of knifeback deformity,hemivertebra deformity,low back stiffness,dyspnea,hip pain and limited movement were significantly negatively correlated with the pelvic muscle volume of the patient(all P<0.05).Conclusions The volume of spinal pelvic muscles in adult spinal malformations is significantly lower than that in asymptomatic subjects.
