腰脊柱结构与椎间盘突出症关系的X线研究

目的：用ｘ线平片探讨腰脊柱结构与椎间盘突出症发病的关系。材料和方法：用髂嵴连线，腰骶移行椎，腰骶角三个参数分析２０８例经手术证实的腰椎间盘突出症患者的术前Ｘ线平片。结果：深座骨盆Ｌ５的患者，Ｌ４－５椎间盘突出发病率高，高骑骨盆Ｌ５的患者，Ｌ５－Ｓ１椎间盘突出发病率高；有腰骶移行椎变异者，腰椎间盘突出发病率高于无变异者；腰骶角在椎间盘突出发病中的意义有待进一步探讨。结论：腰脊柱结构与腰椎间盘突出的发病部位有关，相当部分Ｌ５－Ｓ１椎间盘突出，行经皮椎间盘切除术中，不需髂骨翼钻孔。

The X ray Study of the Correlation between the Iumbar Spine Configuration and Intervertebral Disc Proplapse

Purpose: To explore the correlation of the lumbar spine configuration with intervertebral disc proplapse. Materials and methods: The pre operation lumbar spine X ray pictures of 208 cases who had undergone discectomy for lumbar disc proplapse were analysed with 3 parameters: interiliac line, lumbosacral transitional vertebrae and lumbosacral angle. Results: (1)the patients with the deep seat in pelvis L 5 were associated with a higher likelihood of proplapse at L 4 5 , whereas the patients with high ride in pelvis L 5 associated with proplapse at L 5 S 1. (2) there was a significantly higher incidence of lumbar disc proplapse in the group of lumbosacral transitional vertebrae anomalies. (3) the pathological value of lumbosacral angle in lumbar disc proplapse needs to be further researched. Conclusion: There was a significant correlation of the lumbar spine configuration and the location of the lumbar disc proplapse.
