Abstract

Objectives: Analyzing and comparing of x-ray imaging and computed tomography features in diagnosis of odontoid fracture. Methods: Cross-sectional descripted retrospective studying of 44 odontoid fracture patients were diagnosed in Viet Duc hospital from January 2010 to June 2012. Results: 34 patients with simple odontoid fracture, 7 patients with atlantoaxial dislocations, 3 patients with atlas fracture have been involved in this research. X-ray open mouth views diagnose 81,8% cases of odontoid fracture, lateral views diagnose 68,2%. Type 2, type 3 of odontoid fracture rates was 86,4%; 13,6%, respectively. On computed tomography imaging, odontoid fracture with anterior displacement and horizontal fracture line were highest rates with 68,2% and 55,3% respectively. The Kappa value (0.45) for measuring the reliability between X-ray and CT in findings of odontoid fractures was moderate. Conclusion: Computed tomography imaging is gold standard for diagnose odontoid fracture. However, X-ray is still valuable in clinical practice in medical facilities that have not been equipped with modern specialized equipment. Computed tomography scan images could show directions of the fracture line to lead to treatment decisions.
