Fig. 2C —Virtual glenoid rim reconstruction from CT scans in study group after fracture creation. Image of right-sided glenoid (A) shows defect in anterior edge. Contralateral glenoid (B) is intact. First, intact glenoid is mirrored vertically. Next, joint areas of two glenoid bodies are aligned and projected into each other (C). In this way former glenoid rim defect is filled with intact contralateral side (C and D). To determine precision of reconstruction procedure (E), reconstructed glenoid (blue and red) was superimposed on prefracture image (yellow).
