Subcoracoid impingement is an unusual form of shoulder impingement, and results from narrowing of the coracohumeral interval (space between the tip of the coracoid and the humerus). Narrowing is typically seen in the setting of prior rotator cuff repair, but occasionally also results from congenital narrowing or trauma.

The structures affected are :

  • subscapularis tendon
  • long head of the biceps tendon
  • middle glenohumeral ligament

    • Clinically, patients present with pain in the anterior aspect of the shoulder when the arm is held at the side (adducted, internally rotated and in forward flexion - a.k.a. military parade rest position) .
