Many different types of surgical technics for treating unstable degenerative spondylolisthesis of the lumbar spine has been reported. The most important part of the different procedures is to achieve a solid bony fusion between the two vertebrae. Authors report a new simple method of posterior lumbar interbody fusion in spondylolisthesis. The whole posterior segment of the mobile neural arch is removed and used for fusion. Corticospongiosus dowels and small bone chips are impacted into the disc space emptied totally before. Monosegmental transpedicular fixateur is required for stability. 33 patients with an average follow up of 20 months showed a clinical improvement of 88%. The radiologically proved fusion rate was 90%. Authors achieved good clinical outcome and high bony fusion rate with the one stage operation from posterior approach for treating lumbar spondylolisthesis.
已有报道多种治疗腰椎不稳定退变性椎体滑脱的手术技术。不同手术的最重要部分是实现两节椎体之间的牢固骨融合。作者报道了一种治疗椎体滑脱的新型简单后路腰椎椎间融合方法。将活动神经弓的整个后段切除并用于融合。将皮质松质骨销和小骨块嵌入之前已完全清空的椎间盘间隙。需要单节段经椎弓根固定器来维持稳定性。33例患者平均随访20个月，临床改善率为88%。影像学证实的融合率为90%。作者采用后路一期手术治疗腰椎椎体滑脱取得了良好的临床效果和较高的骨融合率。
