 note = {We evaluated our treatment outcome of patients with traumatic odontoid fracture. We treated 7 patients classified in 6 of type II odontoid fracture and one of type III. Falling down was caused in 3, turnover in 3 and motor vehicle accident in 2. As for the mechanism of trauma, there were 3 of hyperextension, 2 of hyperflexion and 2 of unknown injury. Patients suffered from neck pain as initial symptom in 5, tetraplegia in one and hemiparesis in one. Surgical treatment was performed in 5 patients. Four were operated in anterior odontoid screw fixation, one in C1-2 posterior fixation by using Roosen-Trauschel clamp. One with serious tetraplegia was died from acute cardiac failure 18 days after the trauma, before the surgical treatment. Bony fusion was obtained in 5 of 7 patients. Nineteen months was needed for bony fusion in one with careless post-operative external immobilization. One patient with conservative treatment by external immobilization obtained bony fusion in 5 months, but deformity at the fracture site was remained. Good outcome can be expected for patients with odontoid fractures by early surgical fixation and careful postoperative external immobilization.},
