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.
