The Role of Remplissage in the Setting of Shoulder Instability.

Recurrent anterior shoulder instability is a multifactorial problem for which many solutions exist. Often, the bony surface area of the humeral head and the glenoid needs to be addressed surgically. For large, engaging humeral head defects associated with <25% glenoid bone loss, a remplissage procedure can effectively "fill in" the humeral defect with minimal postoperative morbidity. Remplissage is an effective biological solution that should be considered any time there is a humeral head defect which is contributing to glenohumeral instability.
