Management of odontoid fractures with anterior screw fixation.

Type II odontoid fractures are prone to undergo nonunion. Stabilization of such fractures with anterior screw fixation provides rigid internal fixation and preserves C1-C2 motion. During a 5-year period, 17 patients with displaced type II fractures of the odontoid were treated Thirteen were male and four were female with a mean age of 38.
