Revision Shoulder Instability Surgery After Failed Latarjet: Glenoid Reconstruction Using Distal Tibial Allograft and Humeral Head Reconstruction Using Osteochondral Allograft.

Abstract

Revision surgery for a failed Latarjet procedure is rare and technically demanding with few viable options. Similarly, massive defects to the articular humeral head require thoughtful techniques to recreate a congruent joint. Revision options for failed Latarjet have been studied, but there is yet to be a consensus on graft options. Distal tibial allograft has shown favorable outcomes in midterm data. Humeral head osteochondral allograft has also shown favorable outcomes for very large humeral head defects. However, there is a paucity of literature to demonstrate efficacy of combining the 2 aforementioned techniques. Revision shoulder instability surgery with glenoid reconstruction using distal tibial allograft and humeral head reconstruction using osteochondral allograft restores the glenohumeral articulation while preserving the remaining native bone stock.
