Abstract
Posterior dislocation of the shoulder is uncommon, accounting for 0.9-3.8% of shoulder dislocations. Those associated with fractures are less common. We report one case of posterior dislocation of the shoulder associated with fracture through the neck of the humerus.
The patient was a 49-year-old female who sustained a posterior dislocation of the shoulder associated with neck fracture of the humerus in a traffic accident. Open reduction was performed, and the dislocated Numeral head was reduced and fixed with A-O screws. The follow-up period was 18 months. The postoperative JOA score was 87 points. The radiographs showed no evidence of avascular necrosis.
We emphasize the importance of CT scans in making the diagnosis of a posterior dislocation of the shoulder associated with fracture of the humerus.
