显微减压术治疗腰椎管狭窄症

Micro decompression procedure for lumbar spinal stenosis

目的:总结显微减压术治疗腰椎管狭窄症的临床应用结果。方法:自2001年9月至2006年5月,对87例腰椎管狭窄症患者采用显微减压术治疗。其中,男60例,女27例。年龄43～80岁,平均51岁。L3,42例,L4,547例,L5S138例。结果:87例均获随访,时间18～48个月,平均26个月。按Macnab腰腿痛评定标准:优52例,良28例,差7例,优良率92%。结论:对腰椎管狭窄症的手术治疗重点应放在压迫引起症状的部位,而对无症状的部位不做预防性减压操作。这种显微减压操作老年人更容易耐受。

Objective：To evaluate clinical result of the micro decompression procedure for lumbar spinal stenosis. Methods： From September 2001 to May 2006,87 patients （male 60,female 27） with lumbar spinal stenosis underwent micro-decompression. The age of patients were from 43 to 80 years with an average of 51 years. Among them,2 cases with spinal stenosis occured in L3,4,47 in L4,5,38 in L5S1. Results：All patients were followed up for 18-48 months with an average of 26 months. The results were excellent in 52 cases,good in 28,poor in 7,according to Macnab of back leg pain standard. The rate of excellent and good was 92%. Conclusion：Operative treatment for lumbar spinal stenosis is focused at the areas causing symptomatic neural root compression rather than prophylactic decompression at areas of nonsymptomatic disease. The micro decompression procedures are more likely to be well tolerated by older patients.
