Abstract

With increasing shoulder instability events, the likelihood of a bony lesion of the glenoid and/or humeral head rises. Although bone loss of either the glenoid or humeral head may result in recurrent instability, bipolar lesions have been shown, in particular, to result in a negative and additive effect on glenohumeral stability. In the case of a bipolar lesion comprising severe glenoid bone loss and an engaging, “off-track” Hill-Sachs lesion, the bony foundation of the glenohumeral joint is compromised and bony augmentation is necessary. We present our preferred technique, made up of the application of a distal tibia allograft to address the glenoid bone loss and humeral head allograft to address the Hill-Sachs lesion, for the treatment of a severe bipolar lesion in the setting of recurrent anterior shoulder instability after a failed Latarjet procedure.
