This video discusses the approach to managing glenoid bone loss in the setting of a reverse shoulder arthroplasty. Glenoid bone loss is commonly encountered during reverse shoulder arthroplasty, as 40% of glenoids have been shown to have abnormal wear patterns (Frankle, JSES 2009). With the introduction of virtual planning software, the ability to identify areas of bone deficiency have become more appreciated. The use of humeral head autograft to make up glenoid bone deficiencies is a commonly utilized technique. The surgical technique highlights the ability of virtual software to plan the placement of the glenoid component and anticipate the area that might require graft. Using the 3-dimentional model of the glenoid, a graft from the humeral head is created to match the area of bone deficiency. The model allows selection of the portion of the graft that perfectly matches the glenoid. The patient specific guide can then be used to reproduce the virtual plan. This video walks the surgeon through the planning process, graft preparation, and component placement.
