目的探讨颈椎后路椎管成形术中使用脊柱内固定系统-椎板成型系统（ARCH 钢板）治疗颈椎后纵韧带骨化症（OPLL）的近期临床效果。方法2010年6月至2011年9月，本科在颈椎后路椎管成形术中采用ARCH钢板治疗颈椎后纵韧带骨化症患者12例，其中，男8例，女4例，平均年龄60．5岁，临床疗效采用日本骨科学会（JOA）进行评分及影像学检查评估。结果术后患者神经功能均得到改善，JOA评分平均改善率为39％，椎管扩大82％，差异均有统计学意义（P＜0．05）。无1例发生再关门现象或颈椎反曲畸形。结论对于 OPLL，ARCH 钢板在颈椎后路椎管成形术中的使用，能有效减少再关门可能，术后颈部轴性症状少，近期疗效确切可靠。

Objective To evaluate the short-term results of ARCH plate in cerical expansive open-door laminoplasty(ELAP)for OPLL.Methods From June 2010 to September 2011,a total of 12 cases with OPLL underwent open-door ELAP by ARCH plate fixation and were followed up in our hospital.8 cases were males and 4 cases were female.The average age was 60.5 years.The neurological effect was evaluated by use Japanese Orthopedic Association(JOA)scoring criteria for cervical myelopathy.The ana-tomical effect was analyzed by compare roentgenogram and CT before and after surgery.Results The JOA scores were improved for 39% after the operation,while the saggital diameters of the cervical spinal canaldural after operation was enlarged for 82%(P<0.05).X-ray films and CT scan after operation that there was no occurrence of re-close of door,there was no occurrence of anchor loosing.Conclusion For OPLL,ELAP using ARCH plate fixation bring less occurrence of re-close of door,slight postoperative neck AS,and satisfactory clinical outcomes.
