Abstract: Purpose: The aim of the study was to examine clinical and radiographic results of a cementless humeral surface and to evaluate prognostic parameters for implant failure.<br />Methods: 34 shoulders were examined preoperatively and after a mean 2.7 years. Radiographic parameters, Constant scores (CS) and complications were recorded.<br />Results: The mean CS improved from 27 to 51 points. Eight patients (24%) had an implant revision for secondary glenoid erosion. In the revision group was an increase of the LGHO of 8.4%.<br />Conclusions: The study shows a high revision-rate (24%). Predictor for an implant failure was an operative changing of the LGHO.
