Aseptic Osteonecrosis of the Humeral Head After Anterior Shoulder Dislocation.

Anterior shoulder dislocation is a very common trauma and the main complications are well documented. We report a case of aseptic osteonecrosis of the humeral head following an isolated episode of anterior glenohumeral dislocation without fracture that, to our knowledge, has never been reported in the literature.A 17-year-old male patient sustained an anterior glenohumeral dislocation following a sport accident. It was managed by reduction and immobilization. A radiologically identified aseptic osteonecrosis appeared 6 months later. The instability had been arthroscopically treated. At a follow-up of 4 years, the osteonecrosis has been stabilized leaving a mild arthrosis with stiffness, but without pain.
