title: Complications of type I coronoid fractures in competitive athletes: report of two cases and review of the literature.
abstract: Coronoid fractures have been classified into three types. Elbow instability is a well-recognized complication of type III and less so in type II fractures. Type I fractures have generally been considered to heal uneventfully, with early range of motion. We present two cases of type I fractures in athletes that failed to improve with conservative management. One developed loose body formation and the other a fibrous nonunion with mechanical blockage of elbow flexion. Both patients responded to arthroscopic intervention and returned to full athletic activities. These cases illustrate potential complications with type I coronoid fractures in competitive athletes that should be recognized and treated early.
