Abstract

The treatment of glenoid bone loss in the setting of recurrent shoulder instability remains a challenge. This is because of the nonanatomic nature and resultant incongruous joint resulting from most bony augmentation procedures. We present a novel technique for the management of glenoid bone deficiency by using a fresh osteochondral distal tibial allograft. We have found that the distal tibia has excellent articular conformity to unmatched humeral heads, fits nearly anatomically on the distal two thirds of the glenoid, is composed of dense weight-bearing cortical and metaphyseal distal tibia bone, and provides for a cartilaginous surface for which the humeral head to articulate. This article describes the technique, initial results, and postoperative findings with the use of a distal tibia allograft (the lateral portion of the distal tibia) for the treatment of glenoid bone deficiency (mean loss of 30%) in a series of 3 patients.
