Labral Scaffolding Technique Utilizing Dermal Allograft to Address Subcritical Glenoid Bone Loss in Glenoid Labrum Repair.

A treatment gap exists in the treatment of shoulder instability with subcritical bone loss. In this population, standard arthroscopic labral repairs have been associated with high failure rates. Bone block procedures are associated with low rates of recurrent instability but are associated with a high complication rate and subsequent long-term degenerative changes, making its use less than optimal in subcritical bone loss. We describe the arthroscopic "labral scaffold" technique using dermal allograft with labral reconstruction to address subcritical glenoid bone loss. This technique utilizes a dermal allograft to augment the bony deficit to better restore more native glenohumeral biomechanics with a double-row labral repair and subsequent labral reconstruction.
