Evaluation of Differences in Imaging Findings on Stress-MRI in Throwing Athletes With and Without a History of Ulnar Collateral Ligament Reconstruction

This study aimed to evaluate differences in imaging findings, specifically ulnohumeral joint space widening, on stress-MRI (FEVER view) between throwing athletes with and without a history of ulnar collateral ligament reconstruction (UCLR). The results indicated a significant increase in absolute joint space opening and UCL signal grade in athletes with a UCLR history, although no differences were found in relative joint space opening. The authors conclude that while some imaging differences exist, their clinical significance remains unclear and requires further investigation.
