The rotator cuff compresses the glenohumeral joint during abduction of the arm, an action known as concavity compression, in order to allow the large deltoid muscle to further elevate the arm. In other words, without the rotator cuff, the humeral head would ride up partially out of the glenoid fossa, lessening the efficiency of the deltoid muscle.

One example of a commonly used regional anesthetic is an interscalene brachial plexus block and it has been used in a number of shoulder procedures including instability repairs, proximal humeral prosthetic replacements, total shoulder arthroplasties, anterior acromioplasties, rotator cuff repairs, and operative treatment of humeral fractures.

The axillary nerve supplies two muscles in the arm: deltoid (a muscle of the shoulder) and teres minor (one of the rotator cuff muscles). The axillary nerve also carries sensory information from the shoulder joint. It also innervates the skin, covering the inferior region of the deltoid muscle, known as the regimental badge area. [9]
The cervical spinal nerve 6 (C6) is a spinal nerve of the cervical segment. [1]It originates from the spinal column from above the cervical vertebra 6 (C6).. The C6 nerve root shares a common branch from C5, and has a role in innervating many muscles of the rotator cuff and distal arm, [2] including:
Teres major is supplied primarily by the lower subscapular nerve [4] and additionally by the thoracodorsal nerve (middle subscapular nerve). These are distal to the upper subscapular nerve. These three nerves branch off the posterior cord of the brachial plexus. The nerves that innervate teres major consist of fibers from spinal nerves C5-C8. [4]
The axillary sheath is a fibrous sheath that encloses the axillary artery and the three cords of the brachial plexus to form the neurovascular bundle. [1] [2] [3] It is surrounded by the axillary fat.
