Ipsilateral posterior glenohumeral dislocation in a patient with a history of anterior glenohumeral dislocation

There are few reports of posterior dislocation of the shoulder with a history of anterior dislocation. A 60-year-old man was referred to our hospital after missing a posterior left glenohumeral dislocation. He had a history of an anterior glenohumeral dislocation. In addition to reduction of the posterior dislocation, the surgery involved a combination of repair of the labrum, including the anterior, and reverse rempilissage. We were concerned that the anterior labrum and capsule would be redislocated anteriorly if not repaired, and because excessive repair was thought to induce postoperative contracture, we performed the repair based on intraoperative findings. No re-dislocation has been encountered 18 months after surgery, and joint function is relatively preserved. A patient with a history of anterior glenohumeral dislocation who developed ipsilateral posterior glenohumeral dislocation after injury underwent arthroscopic superior labrum anterior-to-posterior repair and reverse remplissage with favorable postoperative results.
