复发性腰椎间盘突出症的临床诊断与治疗

目的：为复发性腰椎间盘突出症的临床诊断与治疗提供一定帮助。方法：了解31例复发性腰椎间盘突出症患者临床特点及病理改变，并通过再手术作验证和治疗。其中明显外伤史22例，顽固性腰痛18例，合并继发性神经通道狭窄24例。结果：MRI突出诊断符合率为76.47％，再手术验证诊断符合率为77.7％，术后疗效随访6个月～4.8年(平均2．2年)，优良率占83、9％，结论：对疑难诊断目前MRI仍具有一定的优越性；再手术时应彻底切除变性突出、游离的椎间盘组织，解除一切构成神经通道狭窄的因素，同时应注意对椎体稳定性的重建。

TREATMENT AND DIAGNOSIS OF THE RELAPSE LUMBAR INTERVERTEBRAL DISC PROTRUSION

Objective:To determine new way of diagnose and treatment of relapse protrusion of the intervertebal disc. Methods: 31 cases were treated and diagnosed by operation and MRI. The clinical feature and pathological change were observed. Results: The operative successful rate was 83.0% following up 6-58 months. The MRI diagnostic rate was up to 76.47%. Conclusion: MRI always has superiority to case no diagnosed definitely. Re-operation must excise thorough denatured protrusion, dissociate intervertebral disc tissue and all factors of making nerve canal stenosis.
