Four-part proximal humeral fractures are frequently treated with shoulder replacement. Outcome of this procedure has not been standardized, and there are controversy data on range of motion (ROM) and active function of the shoulder. The aim of this study is to compare shoulder prosthesis position (SPP) in terms of version of humeral head and height of stem with clinical subjective and objective outcome. Fifty patients were treated with shoulder hemiarthroplasty for four-part proximal humeral fracture or fracture-dislocation of the humeral head. Radiological examination and CT-scan were performed preoperatively and at follow-up. Clinical outcome evaluation included active and passive ROM, and subjective perspective collected through SF-36, OSQ, ASES, and DASH. No significant correlation between stem height and clinical outcome were found. The prosthesis version correlates with all subjective questionnaires. The ROM was not correlated with stem height and prosthesis version. SPP involves clinical outcome, with great relevance of implant version.
