颈椎椎间融合器临床应用的失误及并发症分析

Analysis of the fault and complications of the anterior cervical fusion cage

目的:探讨颈椎椎间融合器(cervicalfusioncage,CFC)临床应用的失误及并发症产生的原因。方法:随访96例植入CFC的脊髓型颈椎病、急性颈椎间盘突出、外伤性颈椎不稳患者,总结CFC临床应用的失误及并发症,并分析产生的原因。结果:3例CFC的植入位置不当,7例患者产生并发症,包括颈椎的生理前凸减小或变直,CFC旋转、脱位、下沉、不融合。产生失误及并发症的原因有:手术操作不当、CFC自身设计不完善、融合节段过多等。结论:减少失误、降低并发症发生率的对策是严格掌握CFC的适应证、规范手术操作、改进CFC的设计。

Objective:To study what causing the fault and complications of the anterior c ervical fusion cage.Method:Ninety-six patients with cervical spondylotic myelop athy,acute protrusion of cervical disc,traumatic cervical instability were treat ed with the anterior cervical fusion cage.The fault and complications of the ant erior cervical fusion cage were observed.Result:The fault related to anterior c ervical fusion cage occurred in3patients was the misplacement of the cervical ca ge.The complications related to anterior cervical fusion cage occurred in seven patients which included decrement of cervical physiological lordosis or mobiliza tion and rotation,dislocation,subsidence into the adjacent vertebrae,nonunion of the fusion cage.Conclusion:The strategy for diminishing fault and complication s is to select patient correctly,follow the principles of surgical procedure and improve the design of the anterior cervical fusion cage.
