Description

<p>Introduction: The number of patients with odontoid fractures has been increasing with the aging of the population. The authors report the clinical characteristics and treatment results of patients with odontoid fractures.</p><p>Method: A retrospective analysis was performed on 53 patients admitted to Shonan-Kamakura General Hospital who were diagnosed with odontoid fracture. They were divided into two groups: type II and type III. Age, cause of injury, combined injuries, neurological findings, treatment methods, and treatment results were compared between the two groups.</p><p>Results: There were 28 patients in the type II group and 28 patients in the type III group. The mean age was 60.4 years in the type II group and 77.2 years in the type III group. The proportion of males was 60.7% and 40% in the type II and type III groups, respectively. Traffic accidents were the main cause of injury in the type II group. Surgery was performed in 17 (61%) and three cases (12%) of the type II and type III groups, respectively. Bony fusion was confirmed in 78% of type II and 81% of type III patients, excluding those lost to follow-up. Four cases of type II and one case of type III were finally diagnosed as nonunion, but no one suffered neurological deterioration.</p><p>Conclusion: Type II odontoid fracture had a higher proportion of patients of younger age, men, traffic accident and surgical treatment compared to type III. Similar results were obtained with respect to treatment, in principle, with surgery for type II and conservative treatment for type III.</p>
