非椎间隙狭窄型峡部裂腰椎滑脱症的手术治疗

Clinical efficacy of surgical method in the treatment of isthmic lumbar spondylolisthesis with non-narrow type of intervertebral disc.

目的探讨非椎间隙狭窄型峡部裂腰椎滑脱的手术治疗。方法对50例非椎间隙狭窄型峡部裂型腰椎滑脱患者采用短节段固定加椎板、横突间后外侧植骨融合的手术方法进行治疗。结果50例患者症状改善优良率达96%,植骨融合率100%。结论短节段内固定加后外侧植骨融合的手术方法具有手术时间短,不暴露椎管,避免对神经根及硬脊膜的误伤,出血少,费用低等优点。是治疗非椎间隙狭窄型峡部裂腰椎滑脱的一种有效方法。

Objective To investigate the clinical efficacy of surgical method in the treatment of isthmic lumbar spondylolisthesis with non-narrow type of intervertebral disc. Methods 50 patients with non-narrow type of intervertebral disc isthmic lumbar spondylolisthesis were treated with short phase fixation and posterolateral fusion of vertebral plate and transverse process. Results The good rate of symptoms improvement was 96%,and the rate of bone graft fusion was 100%. Conclusion The operation of short phase fixation and posterolateral fusion of vertebral plate and transverse pro-cess has advantages of less operative time,non-exposing vertebral canal,avoiding the mortally dam-age of nerve root and the catheter,less blood loss and the low cost,which is a safe and effective operation method for isthmic lumbar spondylolisthesis with non-narrow type of intervertebral disc.
