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]
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] Usual onset: 20 to 50 years of age [1] Types: Neurogenic, venous, arterial [1] Causes
It passes through the axilla, at first lying behind, and then medial to the axillary vein, and communicates with the intercostobrachial nerve.. It descends along the medial side of the brachial artery to the middle of the arm, where it pierces the deep fascia, and is distributed to the skin of the back of the lower third of the arm, extending as far as the elbow, where some filaments are lost ...
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 ...
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).

When the triad of an ipsilateral Horner's syndrome, shoulder/arm pain and weakness of the intrinsic hand muscles occurs, the presentation is called the Pancoast syndrome. This syndrome is due to involvement of brachial plexus roots and that of sympathetic fibers as they exit the cord at T1 and ascend to the superior cervical ganglion. [11] [10]
