目的 评价单开门微型钢板固定颈椎管扩大成形术的临床效果.方法 对20例需行颈后路单开门椎管扩大成形术的患者,术中将Centerpiece GP8-14 mm钢板两端分别固定于开门后的椎板和门轴侧侧块,通过影像学方法及JOA评分观察所有病例的临床效果.结果 所有患者术后随访3～24个月,平均15个月,影像学评估显示内固定确实,未见神经、血管损伤、颈部轴性症状以及钢板、螺钉脱落移位、椎板塌陷再关门现象.根据JOA评分本组优12例,良4例,好转2例,无效2例,有效率90.0％,优良率80.0％.结论 单开门微型钢板固定可防止颈椎管扩大成形术术后椎板再关门.%Objective To evaluate the application of posterior cervical unilateral open-door laminoplasty using miniplate fixation,How does its alinic effieacy. methods There were 20 patients needed to take posterior-cervical unilateral open-door cervical laminoplasty. During the operation, Centerpiece GP 8—14mm nickelclads were fixed at the lateral mass of vertebral plates and laminae after open-door. The clinical effects of all the cases were observed by imageology methods and JOA scores. Results There was no injury of nerve roots, vertebral artery,cervical cord compression or reclose of vertebral plateo Follow—up ranged 3-24 months,average 15 months,imageology e-valuation found internal fixation well and no injury of vertebral artery,spinal cord injure, screw or nickelclad loosening or displacement, laminae subsidence or reclose of the opened laminae. According to JOA score,the group included twelve excellent cases,four good cases,two improved cases and two ineffective cases,which got a 90.0% effective power and 80.0% excellent and good rates. Conclusion To use mini-plate fixation for cervical laminoplasty is a simple,safe and effective method.
