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]
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 ...
The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four cervical nerves and first thoracic nerve (C5, C6, C7, C8, and T1).This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand.
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).

It is also possible to classify TOS by the location of the obstruction: [citation needed] Anterior scalene syndrome (compression on brachial plexus and/or subclavian artery caused by muscle growth). Cervical rib syndrome (compression on brachial plexus and/or subclavian artery caused by bone growth).
The median nerve is a nerve in humans and other animals in the upper limb. It is one of the five main nerves originating from the brachial plexus.. The median nerve originates from the lateral and medial cords of the brachial plexus, [1] and has contributions from ventral roots of C6-C7 (lateral cord) and C8 and T1 (medial cord).
Pectoralis minor syndrome (PMS) is a condition related to thoracic outlet syndrome (TOS) that results from the pectoralis minor muscle being too tight. [1] PMS results from the brachial plexus being compressed under the pectoralis minor [2] while TOS involves compression of the bundle above the clavicle. In most patients, the nerves are ...
In the case of comprehensive nodal irradiation, which includes axillary levels I, II, and III, as well as a supraclavicular lymph node field, there is a risk of damage to brachial plexus. The risk is estimated to be less than 5% as the brachial plexus radiation tolerance according to (Emami 1991) is 60 Gy in standard fractionation (2 Gy per ...
