Radiographic parameters (fracture morphology, displacement, major tuberosity fractures and Hill\u2013Sachs lesion using initial CT and radiographs) and the proportion of the fractured glenoid were detected (2D-CT-circle-method) and osteoarthritis (A.P. and axial radiographs) was classified according to Samilson\/Prieto.

The a.-\/g.-CMS was 93 (\u00b1\u00a011, 61\u2013100) points, and the WOSI was 81% (\u00b1\u00a022%, 35\u2013100%) on average. The mean intraarticular displacement was 4\u00a0mm (\u00b1\u00a03\u00a0mm; 0\u201314\u00a0mm). The 2D-circle-method showed a mean glenoid fracture involvement of 21% (\u00b1\u00a011, 10\u201352%).
