An uncommon variant of the Essex-Lopresti injury

Abstract

The Essex-Lopresti injury is an extremely rare condition combining radial head or neck fracture, distal radio-ulnar joint dislocation and rupture of the interosseous membrane. However, there are rare or unusual varieties or associated injuries. We report a case of a 46-year-old woman with a posterior dislocation of the radio-humeral joint, a radial shaft fracture, and a distal radio-ulnar joint dislocation. She underwent open reduction and internal fixation of the radial shaft fracture followed by an immobilization by a long elbow splint in supination for 6 weeks. At 18 months of follow-up, she was asymptomatic and she had a full range of elbow and wrist motion and had resumed thoroughly her previous job. The Essex-Lopresti injury results from a complex injury to the forearm axis with resultant longitudinal instability, which can be challenging to treat. There are some variations that can lead to a missed diagnosis resulting in persistent pain and instability of the wrist. The best outcomes are reached with early diagnosis and prompt management.
