摘　　要：[目的]探讨颈椎后路改良Z型单开门椎管扩大成形术治疗颈椎后纵韧带骨化症(OPLL)的疗效。[方法]对36例颈椎后纵韧带骨化症行Z型单开门椎管扩大成形术,参照日本JOA17分评分法,分析所有病例近期疗效。[结果]36例平均随访18.6个月,从术前(8.3±3.2)分改善到(13.8±2.5)分,平均改善率为58.6%。影像显示术前31例颈椎前突型,3例术后变为直线型;5例术前为直线型,术后未变。无1例变为颈椎后突型。颈椎屈伸活动度减少近1/3及轴向痛常发生。[结论]本法治疗颈椎OPLL,减压彻底,椎管扩大充分,防止再关门,是一种安全有效的方法。[ Objective] To investigate the effects of the expansive Z-open-door laminoplasty for the ossification of posterior longitudinal ligaments （OPLL） . [ Methods] Thirty- six cases of OPLL were operated by the expansive Z-open-door laminoplasty. According to JOA score （ 17 Points） the proximate effects of all patients were analyzed. [Results] All cases were followed-up for average 18. 6 months. JOA improved from 8. 3 preoperatively to 13.8 postoperatively. Improved rate averaged 58.6%. Image show： 3 of 31 cases of anterior protruding type were changed to straight type, 5 cases of straight type still kept initial type. None of all cases changed into posterior protruding type after operation. The flexion and extention range of the neck were less 1/3 and the axis-ward pain happened commonly. [ Conclusion] Improved expensive Z-open door laminoplasty for DPLL can decompression clearly. It has advantages of adeguate canal expansion, preventing re- dosing the door, and being safe and reliable.
