Abstract

Isolated teres minor tears are very rare, and only a few case reports have been published in the literature.6, 7, 11, 12 The teres minor functions as an external rotator of the glenohumeral joint and a secondary depressor of the humeral head. Most teres minor tears are associated with larger rotator cuff tears; however, there is minimal literature on how to manage isolated injuries. Posterior humeral avulsion of the glenohumeral ligaments (HAGL) is rare as well and is usually associated with labral tears.1, 3, 4, 10 Only 1 case report has been published in the literature describing a teres minor avulsion and concomitant bony posterior HAGL injury, although it was also associated with a posterior Bankart lesion.12 In this case report we describe a new arthroscopic technique for the repair of a teres minor tear with an associated soft tissue posterior HAGL lesion, without other concomitant injuries.
