     摘要：[目的]报道板棒多轴螺钉系统后路枕颈固定的初步疗效，探讨与其它内固定比较的优势。[方法]14例接受颈枕Summit板棒多轴螺钉系统固定治疗，男9例，女5例。齿突发育不良并C1、2脱位3例，椎管肿瘤4例，C1、2转移癌并病理骨折、类风湿性关节炎并枕颈不稳与颅底凹陷症各2例，寰椎爆裂骨折并寰枢寰枕不稳1例。12例颈痛，13例有不同程度的脊髓损害表现，JOA评分平均124分。[结果]所有螺钉位置良好，无螺钉植入相关并发症。所有颈痛缓解。13例获随访，平均14个月。1例颈枕未融合，枕骨螺钉拔出，其它固定满意并坚固融合。神经功能均有不同程度恢复，JOA评分改善率为630%。[结论]板棒多轴螺钉系统后路枕颈固定安全可靠，取得了满意的临床疗效。与目前常用的固定方法比较具有一定优势。

    Abstract：[Objective]To report the initial outcomes of occipitocervical fixation using platerodpolyaxial screw system and investigate whether this new system offers any advantage over other existing methods of fixation[Method]Fourteen cases(male 9,female 5)accepted cervicooccipital fixation with platerodpolyaxial screw systemThere were 3 cases of odontoid dysplasia with dislocation;spinal canal tumor in 3;2 cases of metastatic carcinoma with pathologic fracture of C1 and C2,rheumatoid arthritis with cervicooccipital instability,and fasilar impression;burst fracture of C1 with oecipitalatlantalaxial instability in 1Twelve cases had neck painThirteen cases had neurological deficits in different degreesJOA score was 124 on average[Result]The positions of all screws were goodThere was no complication related to inserting screwsAll neck pain releasedFourteenmonths followup was obtained on average in 13 patientsCervicooccipital nonunion was in one case and its occipital screws were pulled outTwelve patients had satisfactory fixation and got firm fusionAmeliotate rate of JOA score of the neurological function was 630%[Conclusion]These initial data indicate that posterior occipitocervical fixation using platerodpolyaxial screw system is safe and reliable,and satisfactory clinical outcome can be obtainedThe system appears to offer some advantages over other existing methods of fixation ......
