Understanding the Importance of the Teres Minor for Shoulder Function: Functional Anatomy and Pathology. Williams MD(1), Edwards TB, Walch G. Author information: (1)From Louisiana Orthopaedic Specialists, Lafayette, LA (Dr. Williams), the Fondren Orthopedic Group, Texas Orthopedic Hospital, Houston, TX (Dr. Edwards), and the Centre Orthopédique Santy, Hôpital Privé Jean Mermoz, Ramsay Générale de Santé, Lyon, France (Dr. Walch). Although the teres minor is often overlooked in a normal shoulder, it becomes a key component in maintaining shoulder function when other rotator cuff tendons fail. The teres minor maintains a balanced glenohumeral joint and changes from an insignificant to the most significant external rotator in the presence of major rotator cuff pathology. The presence or absence of the teres minor provides prognostic information on the outcomes of reverse total shoulder arthroplasty and tendon transfers. Clinical tests include the Patte test, the Neer dropping sign, the external rotation lag sign, and the Hertel drop sign. Advanced imaging of the teres minor can be used for classification using the Walch system. Understanding the function and pathology surrounding the teres minor is paramount in comprehensive management of the patient with shoulder pathology. Appropriate clinical examination and imaging of the teres minor are important for preoperative stratification and postoperative expectations. DOI: 10.5435/JAAOS-D-15-00258
