Implication

Cross-sectional analysis shows rotator cuff injuries in 83% of throwing athletes, indicating differing shoulder pathology in traumatic dislocation cases.

Key Points

MR arthrography revealed rotator cuff injuries in 83% of shoulders with glenohumeral instability in overhead throwing athletes, showing significant differences.
Fluctuation sign was present in 71% of shoulders with internal impingement, compared to only 12% in traumatic dislocations (P < .001).
Cross-sectional study assessed the accuracy of MR arthrography in detecting labral injuries during external rotation position using 95 shoulders.
These findings highlight the importance of using specific imaging techniques to differentiate shoulder pathologies in athletes.
