不同类型成人脊柱侧凸的影像学研究

目的 探讨成人脊柱侧凸中最常见的退行性脊柱侧凸(DS)的影像学特征,并与成人特发性脊柱侧凸(IS)相比较,以提高诊断准确率.方法 通过对站立位X线、Bending像的相关参数测量及脊髓造影和CTM检查,回顾性分析98例成人脊柱侧凸的临床资料和影像学特点.结果 DS和成人Is的发病年龄、性别、侧凸的解剖位置和顶点分布上有明显区别,冠状面Cobb角分别为(18.67±7.62)°和(56.2±10.10)°,顶椎旋转度(1.36±0.33)°和(2.34±0.61)°,顶椎偏距(27.4±10.7)mm和(44.7±12.1)mm,主弯的节段数(3.7±2.3)节和(7.1±4.4)节,差异有统计学意义(均P＜0.05).结论 两种侧凸的影像学表现有明显区别,结合临床表现可做出正确诊断.

Imaging diagnosis of degenerative scoliosis and adult idiopathic scoliosis

Objective To analyze and compare the Imaging findings of adult idiopathic scoliosis and degenerative scoliosis which were the most common adult scoliosis, and evaluate imaging characteristics. Method The radiological and clinical data of 98 case, among them, 41 cases of adult idiopathic scoliosis and 57 cases of degenerative scoliosis,were analyzed retrospectively. Result There were differences at presence age, sex ratio, anatomic area of scoliosis and apex between two types of adult scoliosis. The analyses and comparison between the two groups revealed significant change in the Cobb angle, involved segment and convex side orientation (all P <0. 05). Conclusion Adult idiopathic scoliosis and degenerative scoliosis show distinctive imaging characteristics. These characteristics combining clinical data are decisive in diagnosis.
