Odontoid/Dens Fractures

Advanced Emergency Nursing Journal | 2024 | Anthony E. Good, Denise R. Ramponi

Odontoid fractures remain the most common C2 fracture and of those individuals older than 65 years. The type of optimal management remains in question given comorbidities, risk of nonunion, and limitations in mobility when surgical fusion is the treatment selected. These fractures are of particular importance, given the high incident of morbidity and mortality following an odon...

Risk factors of nonunion after anterior screw fixation of Anderson and D’Alonzo type II odontoid fractures

Journal unavailable | Richard Zaccaria, Kenny Hagar, Bernd Wegener, Carl Neuerburg

BackgroundAnderson-D’Alonzo Type II odontoid fractures are common in the elderly and often treated surgically due to high nonunion rates and increased morbidity and mortality associated with conservative treatment. However, high rates of nonunion still occur with surgical treatment and specific fracture characteristics predicting nonunion remain unclear.ObjectiveTo identify mor...
