Résumé / Abstract

We conducted this study to determine whether a test, the posterior impingement maneuver, could be used to prospectively identity articular side tears of the rotator cuff and/or posterior labrum. Sixty-nine athletes presented with posterior shoulder pain that developed during overhand athletics. Injured shoulders were placed into 90° to 110° of abduction, slight extension, and maximum external rotation, and an effort was made to elicit pain deep within the posterior aspect. Overall sensitivity of the test was 75.5%, and specificity was 85%. When only athletes with noncontact injuries (gradual onset of pain) were considered, sensitivity was 95% and specificity was 100%. A positive posterior impingement sign correlated highly with undersurface tearing of the rotator cuff and/or tearing of the posterior labrum in athletes with gradual onset of posterior shoulder pain during overhand athletics.
