椎弓根钉系统联合椎间植骨或融合器治疗退变性腰椎不稳症42例

目的:探讨椎弓根钉系统联合椎间融合器或椎间单纯植骨治疗退变性腰椎不稳症的临床疗效.方法:对42例退变性腰椎不稳症患者采用后路椎弓根钉系统固定加椎间融合器或椎间单纯植骨治疗.结果:全部获得随访,时间6～66个月;术后4～6个月可见植骨灶骨性融合征象,无螺钉断裂,患者腰痛、下肢痛均明显缓解.优31例,良9例,可2例,优良率为95.2%.结论:椎弓根钉系统加椎间融合是治疗退行性腰椎不稳症的有效方法.

Treatment for 42 cases with degenerative lumbar instability with pedicle screw fixation combined with interbody fusion

Objective:To investigate the clinical effects of treatment degenerative lumbar instability with pedicle screw fixation combined with interbody fusion.Methods:Forty-two patients with degenerative lumbar instability were treated with pedicle screw fixation combined with interbody fusion.Results:All cases were followed up for 6 months to 5 years.The bony fusions and no fixation failure were detected in postoperative 4 to 6 months,and the lower limbs pain were significantly relieved.The excellent in 31 cases,good in 9 cases and fair in 2 cases were confirmed and the excellent and good rate was 95.2%.Conclusions:Pedicle screw fixation combined with interbody fusion is effective way for treating the degenerative lumbar instability.
