Abstract

This study evaluates the biomechanical effectiveness of three bone graft options—distal clavicle autograft (DCA), distal tibial allograft (DTA), and medial tibial plateau allograft (MTPA)—for restoring glenoid concavity and anterior shoulder stability in the setting of anterior shoulder instability with glenoid bone loss. Using a cadaveric model with standardized 10-mm glenoid defects, all three grafts restored the bony shoulder stability ratio and maximum anterior humeral translation to levels comparable to the intact glenoid, with no statistically significant differences among them. These findings suggest that DCA, DTA, and MTPA are viable free bone block options for anatomic glenoid reconstruction, though further clinical studies with larger sample sizes are needed to confirm their long-term efficacy and clinical relevance.
