The Limits of Stability: Understanding Posterior Glenoid Bone Grafting in Shoulder Instability
Posterior shoulder instability poses a unique challenge for orthopedic surgeons, particularly in cases of excessive glenoid retroversion. While posterior glenoid bone grafting is a common surgical solution, its effectiveness in extreme retroversion remains uncertain. A recent cadaveric study, done by Dr. Okoroha’s colleagues, sheds light on the biomechanical limits of iliac crest bone grafting (ICBG) for restoring shoulder stability in the setting of posterior instability.
