通用型脊柱内固定系统(GSS)在腰椎不稳症治疗中的近期疗效观察

Preliminary clinical observation of general spine system (GSS) in the treatment of mechanical back pain

目的 :观察GSS对腰椎节段性不稳的固定及治疗效果。方法 :2 0 0 2年 10月～ 2 0 0 3年 9月 ,对 2 5例腰椎不稳症患者。其中 ,男 9例 ,女 16例 ,运用椎板减压、椎管后外侧植骨融合、GSS椎弓根螺钉内固定系统治疗 ,随访 6～ 18个月 (平均 15 7个月 )。结果 :术前JOA评分平均 4 48分的 2 5例患者 ,随访时 14 5分 (P <0 0 1) ,术后 14个月内动态X线检查显示GSS椎弓根螺钉固定患者植骨融合率 10 0 % ,融合节段稳定 ,临床症状改善优良率 96 0 %。结论 :后路运用GSS行椎管后外侧植骨融合内固定对腰椎不稳症患者是一种安全、有效的术式 。

Objective:To observe the effect of general spine system (GSS) for treatment of mechanical back pain.Method:A retrospective study was made between 2002 and 2003 in 25 patiants suffered from mechanical back pain.Result:The JOA score increased significantly from mean 4.48 points to mean 14.5 points ( P<0.01 ).Complete lumbar fusion were found in all cases,and 96.0% good and excellent results in radicular and back pain up to 15.7 months postoperatively.Conclusion:The posterior lumbar spinal GSS instrumentation are safe and effective for severe chronic suffers and its clinical effect is good.
