后路固定椎间植骨融合治疗椎间盘突出症伴腰椎动力性不稳

目的观察后路椎间植骨治疗动力性不稳定的椎间盘突出症的疗效与单纯椎间盘突出症髓核摘除的疗效比较。方法将椎间盘突出症的患者根据腰椎动力位X线和磁共振等影像学检查诊断明确后，本组行髓核摘除术后行后路固定加椎间植骨融合，术后进行1～7年的随访，并对其复发率及后期并发症的观察。结果本组未见内固定物松动，所有病例脊柱节段均获融合，融合率100％，平均融合时间为8（6～12）个月。术后随访1～7年，症状均有明显改善，优良率为96．9％。结论对于腰椎间盘突出症同时还伴有腰椎不稳的患者髓核摘除加后路椎间植骨融合术可以明显减少术后并发症。

Treatment of Protrusion of Intervertebral disc complicalted with Lumbar Instability with Posterior Pedicle Screwed Lumbar Fusion

Objective To investigate clinical results of disc excision and interbody fusion for the treatment of lumbar discogenic pain complicated with motive unsteadiness. Methods 96 patients suffering from lumbar discogenic pain complicated with lumbar instability were diagnosed by the X-ray and MRI, this group undergoing posterior disc excision and interbody fusion with pedicle screw fixation. Results None showed the phenomenon of the loosening of internal fixation cinch in this group,the lumbar of the whole case all had been anfuenced. The rate of confluence is 100%. The average time of the lumbar confluensed was 8 （6- 12） months. The 96 cases with surgical operation were followed-up from 1 to 7 year. The average time was 3 year. The symptoms of 96 cases were greatly improved. The good rate was 96.9%. Conclusion Posterior disc excision and interbody fusion for the treatment of lumbar discogenic pain complicated with motive unsteadiness show satisfactory result.
