目的 探讨脊柱后入路显微内窥镜下手术治疗侧隐窝狭窄的手术方法。 方法 采用自行研制的异型骨凿 ,于显微内窥镜下手术治疗 38例确诊为侧隐窝狭窄的患者。 结果 经 6～ 12个月随访 ,所有患者均无神经损伤等并发症 ;疗效评价 :优 32例 ,良 5例 ,可 1例。 结论 本术式具有创伤小 ,对术后脊柱的稳定性破坏小 。

Objective To introduce a new method of surgical treatment for lateral recess stenosis with MED system. Methods 38 cases of spinal stenosis underwent decompression endoscopically. The operations were performed with posterior microendoscope and self-developed surgical tools,such as special shape osteotome. Follow-up study and evaluation of the results were also made. Results 6～12 months' follow-up showed no nerve damage in all cases. 32 cases were estimated as excellent, 5 as good and 1 as fair. Conclusions MED system is a less traumatic treatment with little influence on the spine stability and the result is good.
