A technique is described for widening the lumbar vertebral canal in the treatment of lumbar stenosis. This method, which preserves part of the posterior arches, has the aim of avoiding the instability which accompanies extensive laminectomies of the whole lumbar spine. The preservation of the posterior arches allows a ligamentoplasty to be made with dacron in stable spines and a combined fusion with internal fixation applied to the posterior arches to be made in cases of spondylolisthesis. The results of a prospective series of 32 patients have confirmed the effectiveness of the method both on the stenosis and on the post-operative spinal stability.
本文描述了一种在治疗腰椎管狭窄症时扩大腰椎管的技术。该方法保留了部分后弓，目的是避免全腰椎广泛椎板切除术后出现的不稳定情况。保留后弓使得在稳定的脊柱中可以使用涤纶进行韧带成形术，而在腰椎滑脱病例中则可以对后弓进行联合融合并应用内固定。对32例患者的前瞻性系列研究结果证实了该方法在治疗狭窄症和术后脊柱稳定性方面的有效性。
