摘要
目的探讨脊柱显微内镜(microendoscopicdiscectomy,MED)治疗腰椎管狭窄症(lumbarspinalstenosis,LSS)的临床应用价值。方法应用脊柱显微内镜手术治疗LSS患者129例,其中中央型34例,神经根型35例,侧隐窝型50例,混合型10例。按不同类型分别行椎管减压、神经根管扩大及侧隐窝减压术。结果术后129例各型腰椎管狭窄症患者,平均随访6.9个月。按NAKAI分级,优:87例,良:38例,可:4例,优良率96.9%。中央椎管型、侧隐窝型、神经根型椎管狭窄3者疗效差异无显著性。3者与混合型椎管狭窄疗效有统计学差异。结论该术式清晰地显露神经根受压情况,从减压的范围、对脊柱的稳定性及临床疗效上看都是可行的,但对混合型椎管狭窄患者的选择上要慎重。
[Objective] To investigate the clinical methods and efficacy of MED surgical treating lumbar spinal stenosis, [Methods] I29 cases of LSS were treated operatively by MED. There were 34 cases type of central stenosis performed spinal stenosis degeneration, 35 cases type of nerve root canal stenosis performed nerve root canal decompression, 50 cases type of lateral recess stenosis performed lateral recess decompression and 10 cases type of compound lumbar stenosis. [Results] The mean follow-up period was 6.9 months. Based on Nakai criterion, 87 eases were evaluated as excellent, 38 eases good and 4 eases fair. The success rate was 96.9%, There was no significant difference among the fore three types. But the results in the fore three types were better than the type of compound. [Conclusions] The MED can decompress the nerve and lead to less trauma little influence on the stability of lumbar vertebrae. First of all, it is safe and practical. But it is relatively prohibited to the type of compound lumbar stenosis.
