The treatment of recurrent glenohumeral instability, especially with a concomitant bony lesion, remains challenging.This is especially true in the case of posterior instability given its less common incidence.Moreover, the presence of an engaging reverse Hill-Sachs lesion in combination with posterior instability will result in the need for a more aggressive treatment option.In comparison with a Hill-Sachs lesion, a reverse Hill-Sachs lesion features greater chondral deficiency that water bottle must be addressed during treatment.

We propose the talus allograft as a potential allograft for treatment of an engaging reverse Hill-Sachs lesion.The superior articular surface of the talus may be used to reconstruct the articular surface of the humeral head.In this technical note, we describe our preferred primary technique for treatment of an engaging reverse Hill-Sachs lesion with recurrent glenohumeral instability through use of a fresh osteochondral talus allograft, as well as discuss the advantages and Slot Car disadvantages of this allograft option.
