可复式椎管扩大成形术的设计与临床应用

Design and clinical application of reducible spinal canal enlargement

目的设计可复式椎管扩大成形术，探讨其临床应用的可行性。方法自病变间隙下位棘突、椎板的上１／３水平截骨，小关节突内缘两侧椎板向上凿开，将棘突、椎板、黄韧带向上掀起，显露、扩大椎管，摘除突出髓核。结果治疗腰椎间盘突出和椎管狭窄３６例，经７～７２个月随访，优良率达１００％。结论该术式适用范围广，病灶切除彻底，操作简单。

Objective To design enlarged reducible type plastic operation and research its clinical value. Method The operation was realized from lower spinous process and upper 1/3 on spondylous disc in affected spatium. Margo medialis bilateral spondylous disc on small processus articularises were chiseled open upward. Immediately spinous process, spondylous disc and yellow ligament was respinated upward and exposed spinal canal Result 36 patients with prolapsed lumbar intervertebral disc or lumbar spinal canal stenosis were treated using the procedure and it is found that the excellent rate accounted for 100% through 7-72 months′ follow up Conclusion The procedure has a wider range of clinical application with simple operation and obtains both complete decompression and good stability of spine.
