Abstract | PURPOSE: METHODS: Fifty-one consecutive patients with complex proximal humeral fractures who underwent primary shoulder arthroplasties with the trabecular metal™ prosthesis were enrolled in this study. At the final follow-up appointment, 42 of the patients (82.4% of the total patients enrolled) were available for both clinical and radiographic evaluation. There were 28 women and 14 men with a mean age of 65.4 ± 10.7 years. The dominant arm was involved in 30 of the cases. According to Neer's classification, there were seven three-part fractures, 27 four-part fractures and eight head-splitting fractures. Additionally, there were 37 hemiarthroplasties and five total shoulder arthroplasties. RESULTS: After a mean follow-up of 37.0 ± 8.4 months (range 24-52 months), the average ranges of motion were: 38.6 ± 15.0° for external rotation, L3 level for internal rotation and 132.3 ± 36.0° for forward elevation. The mean American Shoulder and Elbow Surgeons, visual analogue scale and University of California, Los Angeles scores were 82.1 ± 14.1, 0.4 ± 1.1 and 28.8 ± 5.1, respectively. The post-operative radiographs exhibited an anatomically attached greater tuberosity in 39 of the 42 shoulders. Of the three patients with greater tuberosity complications, as displayed by their radiographs, two were observed with malpositioned tuberosities, while the other greater tuberosity was resorbed. Proximal migration of the prosthesis was observed in all three shoulders with greater tuberosity complications and in two shoulders with an anatomically attached greater tuberosity. No neurovascular injury, infection or prosthetic loosening was identified during the final follow-up appointments. CONCLUSIONS: Satisfactory results can be expected with the trabecular metal shoulder prosthesis for the treatment of complex proximal humeral fractures. The post-operative radiographs demonstrated an anatomically healed greater tuberosity in 93 % of the patients at a minimum follow-up time of two years.
