Reverse Shoulder Arthroplasty Associated With Unnoticed Glenohumeral Dislocation: A Case Report.

Osteonecrosis of the humeral head is seen in rare cases of anterior shoulder dislocations. There are many different surgical procedures that have been developed to repair inveterate anterior glenohumeral dislocation. Reverse shoulder arthroplasty (RSA) is a type of surgery that has been shown to be very effective in patients with cuff tear arthropathy. A 63-year-old female came to our service with an inveterate glenohumeral dislocation. We identified the osteonecrosis of the humeral head and decided to treat her with a reverse shoulder arthroplasty. Osteonecrosis following a glenohumeral dislocation is a rare condition. Treatment with a reverse shoulder arthroplasty allows a fast recovery, good functional results, and a better quality of life.
