退行性腰椎管狭窄症的再认识(附50例分析报告)

Recognition of the Real Causes Related to Symptoms of Lumbar Stenosis

目的 :通过 5 0例的分析 ,明确腰椎管狭窄的症状是由中央椎管狭窄还是由侧隐窝狭窄引起的 ,为临床有限手术提供依据。方法 :对 5 0例腰椎管狭窄症患者的临床症状、影像学检查及手术结果进行分析。结果 :针对引起症状的狭窄部位进行有限手术 ,5 0例患者中手术治疗的优良率为 90 %。结论 :诊断腰椎管狭窄症 ,应该明确症状是由中央椎管狭窄引起的还是由侧隐窝狭窄引起的。退行性腰椎管狭窄症 ,绝大多数是侧隐窝狭窄 ,以双侧椎板开窗入路最为适宜。

Objective:Clinical study of 50 cases of lumbar spinal stenosis were conducted to reveal the causes leading to the symptoms of lumbar spinal stenosis in order to limit field of operation.Method:The symptoms,signs,myelography,or CT scan and the results of the operations were analyzad in 50 cases.Results:Restrained operations were taken according to the nature of stenosis and the excellent rate was as high as 90%.Conclusion:Lateral recess steonsis and central spinal canal stenosis could all be the causes,but in majority it was the lateral recess stenosis that caused the symptoms and the spinal canal should be enlarged by the approach through the interspace of bilateral lmaina.
