Posterior Lumbar Nerve Root Canal Enlargement Operation With Microendoscopy

目的 :探讨脊柱后路显微内窥镜在单节段腰椎管狭窄症手术治疗中的应用。方法 :通过改良手术器械 ,对2 6例单节段腰椎管侧隐窝狭窄病例在脊柱后显微内窥镜下经椎板间隙施行神经根管扩大术。结果 :术后随访 12～ 18个月 ,按Nakai评定分级优 2 0例 ,良 4例 ,可 2例 ,差 0例。术后离床活动时间 2～ 3d ,恢复工作时间 3～ 4周。结论 :通过改良手术器械、扩大了脊柱后路显内窥镜的适用范围。本术式创伤小 ,操作安全 ,缩短患者住院及康复时间。

Objective: Discuss the use of posterior approach microendoscopy operation in the treatment of single lumbar spinal canal stenosis.Methods:Using the improved operative instruments,26cases of single lumbar nerve root canal stenosis were treated by posterior interlamina apporach nerve root canal enlrgement operation with microendoscopy.Results:The patients were followed up from 12 to 18 months.The outcome was excellent in 20 cases,good in 4 cases ,fair in 2 cases and none was poor according to the Nakai Standard Scale.Post-operative off-bed time is 2-3 days,back-to-work time is 3-4 weeks.Concluion:By improving operative instruments to extend the extent of the indications of posterior microendoscopy operation,short patients's time in hospital.
