Video Summary

Jamie Friedman from the University of Connecticut presented a study examining the correlation between advanced imaging measurements of bipolar shoulder lesions (glenoid and humeral head defects) and physical exam findings under anesthesia. Using the glenoid track concept, patients’ imaging was classified as on or off track and compared to a load and shift exam. Among 89 patients, 83% correlation was found between off track lesions and a severe (three plus) instability exam requiring manual reduction. High inter-observer reliability was demonstrated. Though retrospective and from a tertiary center, results suggest imaging reliably predicts shoulder instability severity, guiding surgical decisions. Further outcome studies are planned.
