新型颈椎前路Uniplate钛板系统的初步临床应用

A novel anterior cervical Uniplate titanium plate system-preliminary clinical application

目的:探讨一种新型颈前路Uniplate钛板系统的初步临床应用效果及其设计特点和临床优势。方法:2008年8月-2009年3月,采用Uniplate钛板及碳纤维cage对11例患者进行颈前路单节段椎间盘切除、植骨融合术。其中Hangman骨折伴C2-3椎间盘损伤6例;颈椎间盘突出并颈椎不稳3例;急性颈椎间盘突出2例。评价及分析Uniplate钛板的新型设计、术中操作特点及患者术后恢复情况。结果:所有患者内固定安放顺利,手术时间平均90min,出血平均85ml。无喉返神经及食管牵拉损伤等相关并发症发生。术后X线片示内固定位置良好,颈椎生理曲度恢复。结论:Uniplate颈前路钛板系统的独特设计,使其术中操作更加便捷,显著降低手术难度,而且有效减轻软组织牵拉。其初步临床应用效果较好,但远期效果还需大宗病例长期随访观察。

Objective：To explore the preliminary clinical effect,design characteristic and clinical advantages of a novel anterior cervical Uniplate plate system.Method：From December 2008 to March 2009,11 patients were treated with anterior cervical discectomy fusion at a single segment,using Uniplate titanium plate for fixation and carbon fiber cage for bone grafting.Patients were diagnosed as Hangman’ fracture with C2-3 disc injury in 6 cases,cervical spondylotic myelopathy with cervical instability in 3 cases,and cervical spondylotic esophagopathy in 2 cases.The new design and operating features of the Uniplate titanium plate,as well as rehabilitation and postoperative radiographs of the patients were evaluated and analyzed.Results：All the patients were instrumented successfully.The operating time was at a mean of 90 minutes and the mean blooding volume was 85ml.No stretch injury of recurrent laryngeal nerve or esophagus occurred.The postoperative X-ray images demonstrated good placement of the implants and restoration of cervical curvature.Conclusion：The unique design makes Uniplate more simple and convenient to manipulate in operation,therefore decreasing the difficulty of surgical procedure dramatically and reducing the stretch of soft tissue effectively.Though it showed a good result in preliminary clinical application,its long-term effect should be identified by a long term follow-up to sufficient cases.
