颈椎单开门椎管扩大成形术内固定的选择与疗效

目的观察塑形指骨接骨钛板和Centerpiece钛板在颈椎单开门椎管扩大成形术中的疗效。方法 2009-07—2013-07间应用后路颈椎管扩大成形术治疗并获随访的85例颈椎管狭窄症患者,其中40例采用塑形指骨接骨钛板固定椎板,45例采用Centerpiece钛板固定椎板。回顾性分析两种椎板固定方法的治疗效果。结果 2组患者术后6个月均获得骨性愈合。且出血量、手术时间、引流量、JOA评分改善率及颈椎曲度差异无统计学意义(P0.05)。塑形指骨接骨钛板组住院费用较低,差异有统计学意义(P0.05)。结论塑形指骨接骨钛板和Centerpiece钛板固定椎板均能有效维持椎管的扩大状态。微型钛板固定椎板手术操作简单,不增加手术时间及出血量;而指骨接骨钛板相对费用较低。在患者经济条件允许情况下,Centerpiece钛板是颈椎单开门椎管扩大成形术一种较好的椎板固定方法。

The choices and outcomes to different fixations of Posterior cervical laminoplasty

Objective To investigate the choices and outcomes to different fixations of Posterior cervical laminoplasty.Methods From July 2009 to July 2013,85 patients with Cervical spinal stenosis were operated with Posterior cervical laminoplasty and followed up.40 patients were used with the shaped Titanium plate of finger and 45 patients with the Titanium plate of Centerpiece and we had a retrospective analysis to the clinical outcomes.Results The operation time, blood loss during operation, postoperative drainage,the JOA score,improvement rate and cervical curvature were recorded and compared between two groups,and they showed no significant difference between two groups(P>0.05).All patients were with bony fusion after six months,and the costs of the shaped Titanium plate of finger was relatively lower than that of the Titanium plate of Centerpiece,showing significant difference between two groups(P<0.05).Conclusion Two groups could effectively maintain the spinal canal enlargement and achieve better clinical outcomes and the costs of the shaped Titanium plate of finger was relatively lower.If economic conditions allowed,the Titanium plate of Centerpiece is a good fixation to vertebral plate on the Posterior cervical laminoplasty.
