先天性脊柱侧凸患者脊椎畸形及椎管内畸形的特点

目的:探讨先天性脊柱侧凸(CS)患者脊椎畸形与椎管内畸形的特点及两者间的关系.方法:对我院2005年9月～2007年5月收治的123例CS患者的影像学资料进行回顾性分析.统计不同类型脊椎畸形及不同类型椎管内畸形的特点,分析两者之间的关系.结果:123例患者的脊椎畸形中,28例(22.8%)为形成障碍(FF).43例(35.0%)为分节障碍(SF),52例(42.2%)为混合型障碍(MT).28例FF均在胸腰椎,其中前方结构畸形(AM)19例(67.9%),前后方结构畸形(APM)9例(32.1%);单节段畸形(SM)19例(67.9%),多节段畸形(MM)9例(32.1%).43例SF中,AM 9例(20.9%),后方结构畸形(PM)3例(7.0%),APM 31例(72.1%);SM 9例(20.9%),MM 34例(79.1%);214个节段受累,胸椎196个.52例MT中,AM 6例(11.5%),APM 46例(78.5%);SM 6例(11.5%),MM 46例(78.5%).37例(31.7%)患者有椎管内畸形,其中脊髓纵裂14例,低位脊髓2例,脊髓纵裂合并低位脊髓21例.35例脊髓纵裂患者中34例位于胸椎、腰椎或跨越胸腰椎,33例为SF或MT:23例低位脊髓中21例发生于SF或MT.结论:FF好发于胸椎和腰椎,多为单纯AM,SF和MT好发于胸椎,多为APM.脊椎畸形好发于胸椎,脊髓纵裂好发于胸椎和腰椎,脊髓纵裂和低位脊髓好发于SF或MT.

Analysis of vertebral deformity and intraspinal anomaly in congenital scoliosis

Objective:To investigate the characteristics of vertebral deformity and intraspinal anomaly in con- genital scoliosis(CS) and the relationship between them.Method:A retrospective study of radiographic data of 123 CS patients was performed,and vertebral deformity and intraspinal anomaly of all types were analyzed statistically in order to find the characteristics of the two types of deformities and the relationship between them.Result:123 CS patients consisted of 28 patients(22.8%) with formation failure(FF)...
