Medial Complex Elbow Dislocation: An Unusual Pattern of Injury

Abstract

A 47-year-old man sustained a medial complex dislocation of the right elbow. After initial evaluation, closed reduction was performed. On examination under general anesthesia, the elbow was unstable under varus and valgus stress. Computed tomography scan showed a medial epicondyle and a coronoid fracture. Both medial and lateral approaches were used to fix the epicondylar fragment, the coronoid fragment, and the complex damage to the soft tissues. Immobilization in a cast for 1 week followed by early motion in a dynamic orthosis resulted in a good outcome. Follow up at 2 years showed a range of motion of 110° of flexion-extension and 170° of pronation-supination. Radiographs showed no significant arthritis or heterotopic ossifications.
