AJSM April 2025 Podcast: The Biomechanical Importance of Bone Block Positioning in Glenoid Augmentation: Every Millimeter Matters
Update: 2025-04-28
Description
In the presence of anterior glenoid bone loss (aGBL), options for bony glenoid augmentation include Latarjet procedures and free bone block transfers. Bone graft placement is challenging, and malposition causes complications, such as recurrent instability or osteoarthritis.
In conclusion, in the presence of aGBL, flush bone block placement restores osteochondral glenohumeral stability, while a 1-mm medialized bone block fails to increase stability. Bone block lateralization of 1 mm provides higher stability but is associated with humeral head lateralization.
