非钻孔法经皮穿刺L_5-S_1椎间盘进针法——附侧后路进针途径的解剖学和X线解剖学研究

Anatomic and Radiologic Anatomy Studies on Posterolateral Approach in Percutaneous Discectony:with emphysis on the puncture method at L_5-S_1 intervertebral disc

本研究通过10具尸体的局解和100例腰椎 CT 值进行测量,对经皮腰椎间盘摘除术的侧后方进针途径进行研究,通过50例腰椎对照摄片,设计了一适用于 L_5-S_1椎间盘穿刺的特殊体位和定位方法。结果表明:侧后方进针法为一安全的穿刺途径,但应掌握进针角度宁小勿大的原则;采用笔者设计的特殊体位可使髂骨平均下移2.0cm,同时采用较精确的穿刺点定位可提高 L_5-S_1椎间盘穿刺成功率,130例临床应用成功率达100%。作者首次测得国人与穿刺密切相关的两个穿刺参数值,还就与穿刺通道有关的解剖毗邻组织和穿刺不当可能造成的并发症进行描述和讨论。

A study of 10 cadavers and 100 CT scans of lumbar spine was performed to investigate the topographical anatomy of the posterolateral disc puncture in percutaneous lumbar discectomy.A way of the puncture at L_5-S_1 disc,with comparative plain films of lumbar spine in different positions were taken in 50 cases.The results showed that the pos- terolateral approach for percutaneous discectony was a safe way.However,it is important to have full knowledge of the regional topographical anatomy associated with the puncture tech- nique to avoid the potential neurovascular complications.The special position designed by authors for the puncture at L_5-S_1 disc is useful by lowering the position of iliac crest which hinders the entrance of needle,thus can raise the successful rate of the percutaneous discec- tomy 100% successful rate of the disc puncture at L_5-S_1 disc was obtained in 130 cases.The two puncture parameters of Chinese associated with percutaneous lumbar discectomy were first measured;and also the route including nearby structures,the complications were dis- cussed.
