Reverse shoulder arthroplasty for the treatment of acute complex proximal humeral fractures: Influence of greater tuberosity healing on the functional outcomes

PURPOSE: To investigate the influence of greater tuberosity healing on the functional outcomes of reverse shoulder arthroplasty (RSA) for the treatment of acute complex proximal humeral fractures (PHFs), and to investigate the influence of patient- and surgery-related factors in the healing of the g...

Resumo:PURPOSE: To investigate the influence of greater tuberosity healing on the functional outcomes of reverse shoulder arthroplasty (RSA) for the treatment of acute complex proximal humeral fractures (PHFs), and to investigate the influence of patient- and surgery-related factors in the healing of the greater tuberosity.METHODS: etrospective study including 41 consecutive PHFs treated using RSA with minimum 2-year follow-up. In all the cases, tuberosities were reattached with a standardized technique. All the patients were assessed at the last follow-up with constant score. Body mass index, surgery delay, comorbidities, polyethylene size, glenosphere size, overhanging of glenosphere, and scapular notch were recorded, and their influence in final constant score and in greater tuberosity healing was analyzed. RESULTS: Mean final constant score was of 60.7 points (standard deviation (SD) = 9.9). Greater tuberosity healed in proper position in 68% of the cases. There were no significant differences in constant score between patients with (mean = 61; SD = 9.5) and without (mean = 61; SD = 11.3) the healing of greater tuberosity. All patients scored above 90° in forward elevation. Scapular notch was reported in 14.6% of the cases. Age significantly affected the constant score ( p = 0.008). Comorbidities significantly interfered with greater tuberosity healing ( p = 0.03). There was one reoperation after dislocation. CONCLUSION: In spite of expecting good functional outcome with low complication rate after RSA for acute PHFs, the influence of greater tuberosity healing on shoulder function could not be demonstrated. The presence of comorbidities, but not age or gender, negatively influenced the healing of the greater tuberosity.
