摘　　要：目的 分析采用颈前路单螺钉内固定治疗AndersonⅡ型齿突骨折的临床疗效.方法 收集2005年3月～2011年8月金华市人民医院骨科采用颈前路螺钉内固定治疗的齿突骨折患者临床资料9例,患者均获得随访.年龄27 ～55岁,平均34.5岁.术前常规行颅骨牵引及上颈椎CT检查,9例患者均行单螺钉固定.术后颈围制动8～ 12周,通过X线片、CT了解骨折愈合情况,观察头颈旋转活动情况.结果 随访6～18个月,平均10个月,所有患者随访6个月时均达到愈合,头颈旋转活动无明显受限,1例患者螺钉断裂但亦愈合.结论 经前路单螺钉固定治疗齿突骨折手术简单,操作容易,同时提供良好的稳定性,且保留了寰枢关节运动功能,骨折愈合率高,并发症发生率低,是治疗AndersonⅡ型齿突骨折的有效方法.Objective To analyze the clinical curative effect of anterior single-screw fixation in the treatment of Anderson Ⅱ odontoid fractures. Methods From March 2005 to Auguest 2011,9 patients of Anderson Ⅱ odontoid fractures without spinal cord injury underwent anterior single-screw fixation. All patients with an average age of 34.5 （ 27-55 ） years were underwent traction reduction and CT check before operation, and followed up for 8-12 weeks by immobilization with brace after operation. The fracture healing and head-neck rotation was observed by roentgenograph and CT scan. Results With a mean of 10 months follow-up（ranged 6-18 months）, all cases achieved bony fusion at 6 months after operation, including 1 ease with screw broken up. Conclusion Anterior single-screw fixation has the advantage of simple manipulation, satisfactory stability supplement, a relatively low complication rate, a high fusion rate and good functional recovery. Anterior single-screw fixation is an effective method for the treatment of Anderson Ⅱ odontoid fractures.
