Abstract:

【Abstract】〓Objective〓To report the clinical effect of fresh odontoid fracture treatment with the Halo-Vest external fixation. Methods〓Thirty-two patients with the odontoid fracture undergoing Halo-Vest external fixation were retrospectively investigated..According to the Grauer modified Anderson-D'Alonzo's classification, there were 15 cases of type IIA, 2 cases of type IIB, 6 cases of type IIC and 9 cases of type III. All the patients received occipito-mandibular traction after 3 weeks to Halo-Vest external fixation. Results〓All of the 32 patients were followed up for 4 months to 2 years, an average of 1 year and two months. By imaging examination findings, all patients obtained bone healing in 3 to 4 months after Halo-Vest external fixation..And the patients had sound atlantoaxial joint stability, good flexion extension and rotation function. Conclusion〓Halo-Vest external fixation has the advantage of cervical hyperextension traction and small trauma, and is a economic, simple and safe operation in the treatment of fresh odontoid fracture incuding the type II fracture.

摘要： 【摘要】〓目的〓探讨Halo-Vest外固定架治疗枢椎齿状骨突新鲜骨折的适应证及临床疗效。方法〓回顾32例枢椎齿状突新鲜骨折患者采用Halo-Vest架外固定治疗。按Grauer改良的Anderson-D’Alonzo分型:Ⅱ型23例,其中ⅡA型15例,ⅡB型2例,ⅡC型6例,Ⅲ型9例。本组均采用枕颌牵引3周后改行Halo-Vest架外固定治疗。结果〓本组32例患者全部获得随访,随访时间4个月~2年,平均1年2月,影像学证实全部病人均获得骨性愈合,愈合时间3~4个月,平均3.1个月;所有患者的寰枢椎关节稳定,寰枢椎屈伸和旋转功能恢复良好。结论〓Halo-Vest外固定架具有经济、操作简单安全、创伤小并且有使颈椎过伸牵引复位等优点,是治疗枢椎齿状突新鲜骨折的理想方法,即使对于Ⅱ型骨折也仍是值得推荐的治疗方法。
