Case Discussion

A very old shoulder in bad repair. The more interesting findings are shown here

A ganglion was seen communicating with the AC joint. Dislocation of the long head of biceps tendon medially out of the bicipital groove implied rupture of the transhumeral ligament. The biceps tendon appeared degenerated, probably due to marked lipping at the groove, however it had not completely torn. The posterior labrum had a degenerated appearance and was probably torn. Effusions were seen within the biceps tendon sheath and subscapular joint recess. 

There were numerous other degenerative changes.
