Arthroscopically Assisted Surgery for Coronoid Fractures.

Coronoid fractures are not easily accessed surgically. Despite the majority of cases of coronoid fracture responding to conservative treatment, limited range of motion or instability can develop after such treatment. Therefore, unstable coronoid fractures should be treated surgically to improve clinical outcome. Several approaches and treatment methods have been used for coronoid fractures. The authors report the clinical characteristics, results, and outcomes of 10 cases of Regan-Morrey Type I, Type II, and Type III coronoid fractures treated using a novel arthroscopic technique.
