(A) Photograph of cadaveric dissection: subscapularis muscle-tendon junction (•), latissimus dorsi tendon (★), posterior cord of brachial plexus (), upper subscapular nerve (), and lower subscapular nerve (). The forceps are holding the subscapularis tendon after tenotomy, with the scissors elevating the upper and lower subscapular nerves. (B) Illustration of described anatomy. The inferior one-third muscular portion of the subscapularis as it inserts into the humerus has been excluded to better visualize the path of the axillary nerve as it travels posteriorly at the level of the glenohumeral joint capsule. (C) Magnetic resonance imaging of brachial plexus. Right shoulder magnetic resonance neurography illustrates the nerves in the regional area: suprascapular nerve (small —), upper and lower subscapular nerves (curved —), axillary nerve (medium —), radial nerve (large —). LT, latissimus dorsi tendon; TM, teres major.
