Comparative study of spinal pelvic muscle volume between adult spinal malformations and a-symptomatic subjects
Objective To compare the volume of spinal pelvic muscles between adult patients with spinal deformities and a-symptomatic 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 in-dicators 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 sig-nificantly 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 malfor-mations is significantly lower than that in asymptomatic subjects.
