摘要
目的自制齿突导针定位器应用于颈前路齿突骨折双头螺纹空心加压螺钉内固定术。方法 1999年 10月～ 2000年 2月应用内固定术治疗齿突骨折患者 5例。其中 AndersonⅡ型 4例、 Anderson浅Ⅲ型 1例，术中均使用齿突导针定位器。结果手术用时 2～ 2.5 h，平均 2.25 h；术中出血 20～ 100 ml,平均 60 ml。随访时间 5～ 9个月，平均 6.7个月。 5例患者内固定螺钉位置佳，位于齿突中央，无偏斜。 4例骨性愈合， 1例延迟愈合。结论使用齿突导针定位器可增加放置内固定螺钉的准确性、减少 X线对手术人员的辐射及降低术中污染的可能性。
Objective A design of guide wire localization apparatus for the internal fixation of dens fractures. Methods From October 1999 to February 2000, 5 cases of dens fractures were treated by anterior internal fixation using cannulated compression screws; 4 cases were of Anderson typeⅡ and 1 case was typeⅢ . The guide wire localization apparatus was used for all of the patients during operations. Results The operating time was 2 to 2.5 hours, averaging 2 hours 15 minutes. The amount of bleeding was 20 to 100 ml, averaging 60 ml. The time of follow-up was 5 to 9 months, averaging 6.7 months. The locations of all the 5 cannulated compression screws were excellent, positioning in the center of the odontoid process without deviation. 4 cases healed normally and 1 had delayed bone healing. Conclusion The use of a guide wire location apparatus increased the accuracy of internal fixation of screws in dens fracture, decreased X-ray to radiation to the bodies, and reduced the possibility of pollution in operation.
