三种植骨融合术治疗腰椎滑脱症疗效比较

Compare curative effect of 3 surgical melt operations for lumbar spondylolisthesis

目的比较不同手术方式治疗腰椎滑脱症的疗效差异。方法将96例腰椎滑脱症患者分为后外侧植骨融合术组35例(A组)、后路椎体间植骨融合术组32例(B组)、前路椎体间植骨融合术组29例(C组),分别采用Suk标准及Nakai评分方法来分别判断临床疗效及骨性融合,并进行比较。结果 Nakai评分下A、B、C组的优良率分别为82.9%、81.3%、79.3%(P>0.05),Suk标准评判下融合率分别为71.5%、91.8%、89.0%,B、C组的椎间隙高度要优于A组(P<0.05)。结论三组近中期随访疗效未见明显差异,但前路及后路椎体间植骨融合法在椎间隙高度维持及融合率优于后外侧植骨融合法,但腰椎滑脱症的病因和症状呈多样化,宜具体根据患者具体情况做出相应的选择。

Objective To make a comparison of different melt operations for lumbar spondylolisthesis. Methods 96 lumbar spondylolisthesis patients were divided into three groups such as posterolateral fusion group（A group, 35 cases）, posterior interbody fusion group（B group, 32cases） and anterior interbody fusion group （C group, 29 cases）, respectively making a comparion in preoperation and postoperation by Nakai score and Suk standard. Results The fineness rates of A, B, C groups were respectively 82.9%,81.3%,79.3%（P0.05） by Nokai, and the melting rate of A, B, C groups are respectively 71.5%,91.8%,89.0% by Suk, and the intervertebral space of B, C groups were much higher than that of A group（P0.05）. Conclusion Anterior and posterior interbody fusion is better than posterolateral fusion in the maintainence of intervertebral height and bone fusion, but Spondylolisthesis is complex, the fusion operation way should be selected according to each paitents specific situations.
