Proximal rupture of long head biceps brachii tendon


Proximal long head of biceps brachii tendon rupture with substantial retraction / separation. Bony irregularity at the proximal aspect of the bicipital grove underlying the subscapularis tendon insertion may have resulted in attritional wear of the biceps tendon at this site. A supraspinatus partial insertion 'rim rent' type tendon tear is also seen.
