The purpose of this study was to clarify the results of the postoperative outcome in 4-part fracture of the proximal humerus with dislocation. We operated between 1995 and 2006, and could follow-up 5 shoulders in different cases with 4-part fracture-dislocation of the proximal humerus, Neer Group VI. 2 were males, and 3 were females. The average time from injury to operation was 19 days. The mean age at the time of the operation was 62 years old. Open reduction and internal fixation (ORIF) was done for 1 case, and hemiarthroplasty was done for 4 cases. The average follow-up period was 66 months. We evaluated postoperative results with JOA score. 1 case treated with ORIF had 75 points, and 4 cases treated with hemiarthroplasty, had an average of 61 points JOA score, at the time of the last follow-up. Brachial plexus palsy had occurred in a case operated on 74 days, after injury. After the operation this palsy had recovered. The case after ORIF was complicated by avascular necrosis. In the cases after hemiarthroplasty, absorption of the tuberosity had occurred in 1 case. The JOA score ranged from 45 to 75 points, and postoperative outcome in 4-part fracture of the proximal humerus with dislocation is unsatisfactory.
