ax·il·lar·y nerve

[TA]
nerve that arises from the posterior cord of the brachial plexus in the axilla, passes laterally and posteriorly through the quadrangular space with the posterior circumflex humeral artery; muscular branches pass to the teres minor and wind around the surgical neck of the humerus to the deltoid; terminates as the superior lateral brachial cutaneous nerve.

Additional screws can be inserted in the humeral head by abducting the arm in order to gain access to the inferior epiphyseal holes of the plate without jeopardizing the axillary nerve.
Although Merrell has concluded by recommending shoulder restoration should focus on either a spinal accessory nerve to suprascapular nerve transfer or dual nerve transfer to both suprascapular nerve (SSN) and axillary nerve, the above 2 cases where ICNs were used for SS neurotization achieved 100% M3 or more shoulder abduction.
This case describes a rare triad in a teenager consisting of a HAGL lesion, rotator cuff tear, and axillary nerve palsy that resulted from an anterior shoulder dislocation.

The axillary nerve arises from the posterior cord at the level of the coracoid process, forming an angle towards the deltoid muscle, which it innervates (Fig.
It is important to continue the release medially under and around any inferior humeral spurs in order to protect the axillary nerve. As the soft tissues are released, the arm is continually and slowly externally rotated and abducted to allow exposure of the inferior humeral head.
