20岁以下青少年腰椎间盘突出症影像学分析

The Analysis of hnaging Lumbar Intervertebral Disc Protrusion in Adolescent

目的探讨青少年腰椎间盘突出症的病因、临床及影像学表现特点。方法回顾性分析16例青少年腰椎间盘突出症的临床和影像学表现。结果L4-5，L5-S1是椎间盘突出的好发部位。16例青少年腰椎间盘突出症的主要CT、MR表现为：①中央型腰椎间盘突出2例，占12．50％；②周围型腰椎间盘突出14例，占87．50％。结论本病的发生与外伤和腰骶部发育异常有关。X线平片对青少年椎间盘突出诊断价值不如CT和MR，CT和MR检查准确性高，且为无创性检查，是诊断青少年腰椎椎间盘突出较为理想的检查方法。

Objective To investigate the pathogenesis,clinical manifestations and imaging findings of lumbar intervertebral disc protrusion in adolescent. Methods The clinical and imaging representations of 16 cases with lumbar intervertebral disc protrusion in adolescent were retrospectively analysed. Results The location of disc herniation occurred frequently at thelevel of L4.5 and L5-S1 intervertebral space. The main CT and MR findings included ：（1）central type 2 cases （ 12.50% ） ; （2）Periphery type 14 cases （87. 50% ）. Conclusion This disease is closely related to trauma and develop mental anomaly. CT and MR is accurate and non-lnvasive means,especially lumbar intervertebral disc protrusion in the adolescent.
