摘要
目的探讨下颈椎关节突关节倾角测量在后路侧块螺钉固定术中的应用。方法对2006年11月至2008年11月于我院就诊的50例颈椎骨折脱位患者,通过测量下颈椎关节突关节倾角,后路侧块螺钉固定术中下颈椎置入螺钉以侧块中点稍内为钻孔进针点,选择进针方向在水平面外倾20°,矢状面上斜40°进针,植入骨屑,选择合适孔距的钢板和螺钉,拧入螺钉使钢板固定伤段颈椎。结果50例颈椎骨折脱位患者中,6例完全瘫者躯干感觉部分恢复,43例不全瘫者JOA评分为13～17分,1例呼吸衰竭死亡。结论下颈椎侧块螺钉置入时应根据不同患者、不同椎体术前测量的关节突关节倾角决定置入侧块螺钉的角度。
Objective To explore the application of lower cervical spine facet joint angle measurements in the posterior lateral mass screw fixation surgery.Methods Though the measurements of lower cervical spine facet joint angle,the inner of posterior lateral mass was considered to be the internal fixation point in posterior lateral mass screw fixation surgery.It was chosen horizontal plane extraversion 20° and sagittal planes acclivity 40° to be the drilling internal fixation point,grafting to the marrow chip,and selected the suitable plate and screw,and then wring the screws to make the injury segment cervical vertebrae fixation.Results During the 50 cases of lower cervical vertebrae injury,6 patients with complete paralysis had limited recovery in sensation,17 cases with incomplete paralysis had reached 15.2 according to JOA score,1 case was dead for respiratory failure.Conclusion That the lower cervical spine facet joint angle in the posterior lateral mass screw fixation surgery should be decided according to the different cases,different lower cervical spine facet joint angle before surgery.
