title: Shoulder arthroplasty for late sequelae of proximal humeral fractures.
abstract: Twenty-eight patients with sequelae of proximal humeral fractures were treated with shoulder arthroplasty and were reviewed with a mean follow-up of 47 months. There were 8 malunions, 7 osteonecrosis, and 2 nonunions of the proximal humerus. Degenerative joint disease without any distortion of the tuberosities had developed in 11. We performed 8 total shoulder arthroplasties and 20 hemiarthroplasties. On the basis of the Neer criteria, the results were satisfactory in only 64%. Fifteen patients had superior migration of the implant. One patient had to be reoperated on because of deep infection. The prognosis was influenced positively by the integrity of the rotator cuff at surgery, whereas the need for greater tuberosity osteotomy worsened the final result. The data suggest that malunion of the greater tuberosity can be tolerated if it does not compromise acceptable positioning of the humeral component. However, if there is a malunion of the greater tuberosity with major displacement, an osteotomy must be performed, with unpredictable results.
