Arthroscopic Glenoid Reconstruction, Bone Blocks and Transfers in the Management of Complex Shoulder Instability With Bone Loss: Advanced Concepts and Surgical Techniques: Interactive and Case -Based (AANA22)-Understanding and Applying the Glenoid Track

Video Transcription

Video Summary

Dr. Shea discusses shoulder instability and bone loss challenges, emphasizing the glenoid track concept for assessing bone defects on both glenoid and humeral sides. He explains measuring bone loss using the glenoid diameter and calculating the glenoid track with a simple formula involving 0.83 times the glenoid diameter minus bone loss. Comparing this to the Hill-Sachs lesion size determines if a lesion is "on-track" or "off-track," guiding treatment. Off-track lesions have high failure rates with arthroscopic Bankart repair, while on-track lesions fare better. He advocates using remplissage for any Hill-Sachs lesion and open procedures for significant bone loss, highlighting the concept's clinical importance.
