We report 2 cases of traumatic posterior dislocation of the shoulder joint with greater and lesser tuberosity fracture.<BR>Case 1; The patient was a 19-year-old man who had tumbled down in construction site and hit the ground with his left elbow. He visited our emergency room, and radiological examination revealed posterior dislocation of the left shoulder joint with greater and lesser tuberosity fracture. Closed reduction of the glenohumeral joint was perfored, however greater and lesser tuberosity had been displaced. We performed an open reduction and fixation of left tuberosity using three cannulated cancellous screws. At 12 months after operation, active range of motion was improved with flexion to 160 degrees, external rotation to 50 degrees, internal rotation to level of the Th10. He had no pain and could return to his previous work.<BR>Case 2; The patient was a 17-year-old man who had follen a motocross accident and hit the ground on his left shoulder. He visited the emergency room of a nearby hospital, and radiological examination revealed posterior dislocation of the shoulder joint with greater and lesser tuberosity fracture. Glenohumeral joint was unstable after closed reduction, therefore he was introduced to our hospital. We performed an open reduction using four cannulated cancellous screws on the day he visited our hospital. 17 months after operation, active range of motion was improved with flexion to 145 dgrees, external rotation to 60 degrees, internal rotation to level of the L3. Radiological examination revealed humeral head necrosis, however he had no pain and could return to his previous work.
