A patient suffers a traumatic fracture of the surgical neck of the humerus which was conservatively treated. He presents two months later with weakness in his arm. From the image, which of the following muscles will have undergone atrophy?

Answer E

1. A supraspinatus B infraspinatus C Subscapularis D Teres major E teres minor

2. The axillary nerve or the circumflex nerve is a nerve of the human body, that originates from the brachial plexus (upper trunk, posterior division, posterior cord) at the level of the axilla (armpit) and carries nerve fibers from C5 and C6. The axillary nerve travels through the quadrangular space with the posterior circumflex humeral artery and vein to innervate the deltoid and teres minor.

3. During humeral neck fracture, the axillary nerve can be damaged. Evaluation should begin with inspection of the soft tissues and skin, as elderly patients are susceptible to poor wound healing. A full neurologic examination can be difficult following trauma, but function of the fingers, wrist, and elbow can often be evaluated.

4. Axillary nerve innervation of the deltoid needs to be tested as reverse shoulder arthroplasty (RTSA) is a viable treatment option that requires an intact and innervated deltoid. The axillary nerve also innervates Teres Minor
