Subcritical Thresholds of Glenoid and Humeral Sided Bone Loss Predict Failure after Bankart Repair

Glenoid and humeral sided bone loss are both independent risk factors for failure after arthroscopic Bankart repair. The purpose of this study was to determine the combined effect subcritical levels glenoid on 171 individuals with minimum 2 years follow up who underwent primary repair between 2007-2015 were included in study. measured using track model. Cases defined as sustained a subluxation or dislocation event index procedure, while controls did not. Subjects stratified by age (20+ versus < 20 years). Receiver operating curves (ROC) generated threshold that could best predict failure. There 53 cases 118 controls. Increased (p .001) humeral-sided = .013) independently predicted ROC analysis demonstrated values 12% (AUC 0.62) 13 mm 0.60) predictive Combined thresholds 10% 10 successfully outcomes 49/56 (87.5%) over 79/117 (67.5%) under 20. Humeral had an additive older primarily responsible younger individuals. Both accurately failure, particularly These results suggest bipolar lesions may be at higher than previously thought.
