Glenoid bone loss in primary and revision shoulder arthroplasty.

The management of glenoid bone loss is a major challenge in both complex primary and revision arthroplasty surgery. To deal with this problem, a number of techniques have been advocated, although there has been no previous systematic review of the literature. In the present review, we have attempted to identify a coherent strategy for addressing this problem, taking into account the degree of bone loss, the advantages and limits of standard implants, bone reconstruction techniques and the use of customized prostheses.
