Abstract

Medial subluxation or dislocation of the long head of the biceps is often linked to rotator cuff tear, especially a tear of the subscapularis tendon. Isolated medial dislocation of the long head of the biceps without rotator cuff tear is extremely rare. There has been only one published report of an isolated dislocation of the long head of the biceps with intact subscapularis and supraspinatus tendons after traumatic posterior dislocation, by tear of the rotator interval. We report a case of isolated medial dislocation of the long head of the biceps without rotator cuff tear and include a review of the literature.

  Fig. 1 (A) Axial T2-weighted magnetic resonance image demonstrates medial dislocation of the long head of the biceps over an intact subscapularis tendon and a lobulated cystic mass around the spinoglenoidal groove. (B) Oblique coronal T2-weighted magnetic resonance image demonstrates a SLAP II lesion.
