Specialized Toolkit Series: Shoulder Instability-Posterior Glenoid Bone Block Augmentation for the Failed Reverse Bankart Repair

Posterior Glenoid Bone Block Augmentation for the Failed Reverse Bankart Repair

Video Transcription

Video Summary

The speaker discusses revising failed posterior labrum repairs complicated by posterior glenoid bone loss, a challenging issue with high failure and revision rates. Posterior bone loss alters glenoid anatomy and stability, often requiring careful assessment beyond standard imaging. They present an arthroscopic technique using distal tibial allograft augmentation, adapted from anterior procedures, for cases with significant bone loss or revision repairs. The procedure involves precise graft preparation, positioning, and fixation to restore stability while preserving soft tissues and protecting nerves. Early outcomes are promising, with patients regaining function, but longer-term data are needed. The approach offers a minimally invasive option for difficult posterior shoulder instability.
