目的:观察特发性脊柱侧凸(IS)患者凸、凹侧椎旁肌横截面积是否存在差异,探讨椎旁肌改变与脊柱侧凸的关系。方法:IS患者31例,女20例,男11例,年龄12～18岁,Cobb角范围28°～76°,平均53°±12°,在CT片上测量上终椎、顶椎、下终椎双侧椎旁肌横截面积。同龄非脊柱畸形患者(对照组)20例,女8例,男12例,年龄5~15岁,在CT片上测量T8、T10双侧椎旁肌横截面积。比较两组双侧椎旁肌的横截面积。结果:IS患者上终椎、顶椎、下终椎凸侧椎旁肌横截面积均大于凹侧,差异有统计学意义(P<0.05);凸/凹侧椎旁肌横截面积比值顶椎>上终椎>下终椎;Cobb角>50°和<50°患者顶椎水平凸/凹侧椎旁肌横截面积比值无统计学意义(P>0.05),顶椎水平凸/凹侧椎旁肌横截面积比值与Cobb角无显著相关性。对照组双侧椎旁肌横截面积差异无统计学意义(P>0.05),左/右侧椎旁肌横截面积比值亦无统计学意义(P>0.05)。结论:特发性脊柱侧凸患者双侧椎旁肌发育不对称,凸侧椎旁肌横截面积大于凹侧,且在顶椎水平差异最大,但顶椎水平椎旁肌横截面积凸/凹侧比值与Cobb角无明显相关性。
Objective: To observe the differences of the cross-sectional area of paravertebral muscles between the convex and concave side of patients with idiopathic scoliosis (IS), and to explore the relationship between paravertebral muscle and scoliosis. Methods: 31 patients with IS, 20 males and 11 females, aged 12 to 18 years old with Cobb angle ranging from 28 ° to 76 ° with an average of 53 ° ± 12 °. Spinal bilateral paraspinal muscle cross-sectional area. Twenty patients with non-spinal deformity at the same age (control group), 8 women and 12 men, aged 5-15 years. The cross-sectional area of bilateral paravertebral muscles of T8 and T10 were measured on CT images. The cross-sectional area of bilateral paraspinal muscles was compared between the two groups. Results: The cross-sectional area of the paravertebral muscles on the convex side of the superior vertebra, the apical vertebra and the inferior vertebra in IS patients were significantly larger than that of the concave side (P <0.05). The ratio of the cross-sectional area of the paravertebral muscles in the convex / The ratio of the cross-sectional area of the paravertebral muscles at the level of the vertebral vertebra to the level of the vertebral vertebra> 50 ° and <50 ° was not statistically significant (P> 0.05) The paraspinal muscle cross-sectional area ratio had no significant correlation with Cobb angle. There were no significant differences in the cross-sectional area of bilateral paraspinal muscles in the control group (P> 0.05), nor did the cross-sectional area ratio of the paraspinal muscles in the left and right sides (P> 0.05). Conclusions: The bilateral paravertebral muscles of idiopathic scoliosis patients have asymmetric development, the cross-sectional area of the paravertebral muscles on the convex side is larger than the concave side, and the difference between the vertebrae and vertebrae is greatest. However, Concave side ratio and Cobb angle no significant correlation.
