The brachial plexus is most compact at the level of the trunks formed by the C5–T1 nerve roots, so nerve block at this level has the greatest likelihood of blocking all of the branches of the brachial plexus. This results in rapid onset times and, ultimately, high success rates for surgery and analgesia of the upper extremity, excluding the ...
Thoracic outlet syndrome; The right brachial plexus, viewed from in front.: Specialty: Vascular surgery, thoracic surgery: Symptoms: Pain, weakness, loss of muscle at the base of the thumb, swelling, paleness, bluish coloration [1] [2]
A brachial plexus injury (BPI), also known as brachial plexus lesion, is an injury to the brachial plexus, the network of nerves that conducts signals from the spinal cord to the shoulder, arm and hand. These nerves originate in the fifth, sixth, seventh and eighth cervical (C5–C8), and first thoracic (T1) spinal nerves, and innervate the ...
It is also known as brachial plexitis, and results in brachial plexus inflammation without any apparent shoulder injury. PTS can manifest with severe pain in the shoulder or arm, followed by numbness and weakness. [5] Parsonage–Turner syndrome occurs in about 1.6 out of 100,000 people every year. [6]
There is always a noticeable difference in the compound muscle action potential's dispersion, and conduction block is commonly experienced. [26] An MRI can show proximal nerve or root enlargement and gadolinium enhancement, which indicate active inflammation as well as demyelination in the brachial plexus [27] or cauda equina. [28]
Brachial plexopathy is often caused from local trauma to the brachial plexus, as can happen from a dislocated shoulder. The disorder can also be secondary to compression or stretching of the brachial plexus (for example, during a baby's transit through the birth canal, in which case it may be referred to as Erb's Palsy or Klumpke's palsy).

More research is needed on Ozempic long-term side effects. Some severe side effects with long-term consequences may include pancreatitis, acute kidney injury, gallstones, gallbladder disease ...
While chronic progressive brachial monoplegia is uncommon, syringomyelia and tumors of the cervical cord or brachial plexus may be the cause. The onset of brachial plexus paralysis is usually explosive where pain is the initial feature. Pain localizes to the shoulder but may be more diffuse, or could be limited to the lower arm.
