Glenoid Reconstruction With Distal Tibia Allograft for Recurrent Anterior Shoulder Instability

Anterior glenoid bone loss is present in nearly all cases of recurrent anterior glenohumeral instability. Treating glenoid bone loss in the setting of recurrent instability is challenging, and often, soft tissue stabilization procedures in isolation are inadequate. The nonanatomic, incongruous joint resulting from most bony augmentation procedures has motivated investigators to find an alternative solution. Recently, the use of fresh distal tibia allograft has been reported as an anatomic, osteoarticular reconstructive option for restoring the glenoid arc and maintaining glenohumeral congruency. This article describes the surgical technique for glenoid reconstruction with distal tibia allograft for recurrent anterior shoulder instability.
