BACKGROUND: Displaced two-part fractures of the greater tuberosity requiring surgical intervention are rare and the literature gives only few data of functional results after operative treatment. The purpose of this study was to analyze functional and radiographic long-term results in patients who had undergone surgical treatment of displaced greater tuberosity fractures and to compare those results with the results of patients who had been treated nonoperatively. MATERIAL: From a prospectively gathered database, we retrospectively analyzed functional and radiographic results of 52 patients with operative treatment of displaced greater tuberosity fractures at an average time of 5.5 years (range, 2-11 years) after trauma. Those results were compared with the functional and radiographic outcome of nine patients with equal injuries, who had been treated nonoperatively. Functional results were defined by three supplementary shoulder scores: the Vienna Shoulder Score (VSS), the Constant Score (CS), and the University of California, Los Angeles (UCLA)-Score. Radiographic results were assessed based on accurate radiographs in two planes (anteroposterior and axillary). Patients underwent either open reduction and internal fixation (n = 30) or closed reduction and percutaneous internal fixation (n = 22). RESULTS: Thirty-four patients (65%) achieved good functional results (CS >80 points, VSS <8 points, UCLA >28 points) and eight patients (15%) had excellent results with a maximum of points on two of three shoulder scores. Ten patients (20%) experienced satisfactory results with two-thirds points on two of three shoulder scores. All fractures healed without any signs of nonunion or relevant loss of reduction. In nine patients (17%) we had a minimal loss of reduction (<5 mm) to superior, but there was no significant influence on shoulder function. In comparison of the operative techniques, patients with open reduction and internal fixation had slightly better functional results than did those with closed reduction and percutaneous internal fixation, but this was statistically not significant (p > 0.05). In comparison of the results of the surgical study group and the nonoperative control group, patients with reduction and fixation of greater tuberosity fractures had significantly better results on shoulder function than did those with conservative treatment (p < 0.05). CONCLUSION: Surgical treatment of displaced greater tuberosity fractures revealed good functional and radiographic results. Reduction and fixation of those fractures is recommended because patients with nonoperative treatment showed significantly worse results. Similar results can be achieved for open reduction and internal fixation, or closed reduction and percutaneous fixation.
