Figure 19 - A posterior inferior opening wedge osteotomy is created one centimeter medial to the glenoid lip in the same as the face of the glenoid articular surface. The depth of the osteotome is controlled by paying attention to the sterile tape mark. This osteotomy is opened with successive levering steps to ?bend? the bone, rather than breaking. The glenoid surface is observed as the osteotomy is deepened to prevent penetration of the joint surface.
