The block can be extended by placing an indwelling catheter, which may be connected to a mechanical or electronic infusion pump for continuous administration of local anesthetic solution. A catheter may be inserted at the interscalene, supraclavicular, infraclavicular or axillary location, depending on the desired location of nerve block.
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 .
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]
A temporary nerve block ... this technique has been used in patients with chronic shoulder pain as a way to perform a neurectomy of the suprascapular nerve ...
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.
This notch is converted into a foramen by the suprascapular ligament, and serves for the passage of the suprascapular nerve. [2] The suprascapular vessels vary in number as well as in their course as they run at the suprascapular notch site. The suprascapular artery pass above the suprascapular ligament in most cases. The suprascapular vein may ...
A nerve decompression is a neurosurgical procedure to relieve chronic, direct pressure on a nerve to treat nerve entrapment, a pain syndrome characterized by severe chronic pain and muscle weakness. In this way a nerve decompression targets the underlying pathophysiology of the syndrome and is considered a first-line surgical treatment option ...
subclavian nerve (C5-C6) 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.
