撬拨复位法在腰椎滑脱术中复位的应用价值

目的评价撬拨复位法在腰椎滑脱手术中解剖复位的治疗效果。方法对37例不同程度的腰椎滑脱,按照症状、复位情况、术前、后X线比对进行疗效评价。结果 37例均获得随访,随访时间2～3.5年,平均(27±3)月。术前腰腿痛症状基本消失,间歇性跛行21例消失,2例减轻,下肢皮肤感觉迟钝大部恢复。1年融合率94.6%(35例),2年融合率97.3%(36例)。根据NaKai评分标准:优25例,良9例,可3例,无钉棒断裂并发症。根据JOA评分法测定,术后明显优于术前。结论内固定系统结合撬拨复位法在腰椎滑脱手术中能够获得解剖复位的效果。

Application value of percutaneous reduction by leverage in reduction of lumbar spondylolisthesis

Objective To evaluate the effect of percutaneous reduction by leverage on anatomical reduction of lumbar spondylolisthesis.Methods Therapeutic evaluation was performed in thirty-seven lumbar spondylolisthesis cases according to symptom,fracture resetting,preoperative and postoperative X-rays.Results Thirty-seven patients were followed up for 2 to 3.5 years,(27±3) months averagely.Preoperative backleg pain symptoms almost disappear,21 cases of intermittent claudication disappear,2 cases alleviate,most of lower limb skin feel numb recovered.1 year fusion rate was 94.6%(35 cases),2 years fusion rate was 97.2%(36 cases).According to the NaKai score standard,25 cases were evaluated as excellent,9 cases as good and 3 cases as medium.No nail bar fracture occurred.According to the JOA score standard,postoperative was better than before.Conclusion Internal fixation and percutaneous reduction by leverage might be effective to treat lumbar spondylolisthesis.
