CT confirmed an anterior glenoid fracture involving approximately 25% of the articular surface, with a concomitant large, Hill-Sachs lesion (Figure 1).

Hill-Sachs lesion and small rotator cuff tear were observed. Humeral head osteotomy was performed, and the anterior glenoid fracture was visualized and inspected (Figure 2).
Clinical photos demonstrating provisional fixation with K-wires (a) and definitive fixation with compression of fracture fragments through the glenoid baseplate (b).

After reduction and provisional fixation of the glenoid fracture with K-wires, the glenoid was then prepared by drilling and tapping the central hole to accept the standard baseplate (Figure 3(a)). The fragment was found to be stable and anatomically aligned following placement of the peripheral screws (Figure 3(b)).

Radiographs obtained at that time demonstrated RSA in anatomic position with healing of the glenoid fracture through baseplate compression (Figures 4(a) and 4(b)).

Postreduction CT demonstrated a large, comminuted anteroinferior glenoid fracture involving approximately 35% of the glenoid diameter (Figures 5(a) and 5(b)).
