Since the suprascapular nerve provides sensory information to 70% of the joint capsule, blocking this nerve can help with post-operative shoulder pain. A nerve stimulator, ultrasound device, or a needle insertion that is 1 cm above the midpoint of the scapular spine can quickly block the suprascapular nerve. [24]
To achieve an optimal block, the tip of the needle should be close to the nerves of the plexus during the injection of local anesthetic solution. Commonly employed techniques for obtaining such a needle position include transarterial, elicitation of a paresthesia, and use of a peripheral nerve stimulator or a portable ultrasound scanning device ...
The suprascapular nerve is a mixed (sensory and motor) nerve that branches from the upper trunk of the brachial plexus. It is derived from the ventral rami of cervical nerves C5-C6. It provides motor innervation to the supraspinatus muscle , and the infraspinatus muscle .
For example, this technique has been used in patients with chronic shoulder pain as a way to perform a neurectomy of the suprascapular nerve with less risk of damage to nearby muscles within the rotator cuff. [10]
The superior transverse ligament (transverse or suprascapular ligament [1]) converts the suprascapular notch into a foramen or opening.. It is a thin and flat fascicle, narrower at the middle than at the extremities, attached by one end to the base of the coracoid process and by the other to the medial end of the scapular notch.

suprascapular nerve (C5-C6) anterior division of upper trunk (C5-C6, forms part of lateral cord) posterior division of upper trunk (C5-C6, forms part of posterior cord) The axillary, radial, musculocutaneous and median nerves all contain axons derived from the upper trunk.
