Due to its long, relatively superficial course, the long thoracic nerve is susceptible to injury, either through direct trauma or stretch. [7] Mechanisms of injury include: nerve lesions. [3] various sports injuries, typically occurring from a blow to the ribs underneath an outstretched arm. surgery for shoulder and thorax. [8]
This is typically due to damage (i.e. lesions) of the long thoracic nerve. [1] [7] This nerve supplies the serratus anterior, which is located on the side of the thorax and acts to pull the scapula forward. Serratus anterior palsy is a dysfunction that is characteristic of traumatic, non-traumatic, and idiopathic injury to the long thoracic ...

The neurogenic type is the most common and presents with pain, weakness, paraesthesia, and occasionally loss of muscle at the base of the thumb. [1] [2] The venous type results in swelling, pain, and possibly a bluish coloration of the arm. [2] The arterial type results in pain, coldness, and pallor of the arm. [2]
[1] [2] Spinal nerve injury does not cause neck, mid back pain or low back pain, and for this reason, evidence has not shown EMG or NCS to be helpful in diagnosing causes of axial lumbar pain, thoracic pain, or cervical spine pain. [3] [4] [5] [1]
The long thoracic nerve that supplies the serratus anterior muscle is vulnerable during certain types of surgery (for example, during lymph node clearance from the axilla for breast cancer). Damage to this nerve is the most common cause of winged scapula. [6]
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve, though this may also refer to nerve root compression (by a herniated disc, for example).
The most significant impact of magnetic resonance neurography is on the evaluation of the large proximal nerve elements such as the brachial plexus (the nerves between the cervical spine and the underarm that innervate shoulder, arm and hand), [9] the lumbosacral plexus (nerves between the lumbosacral spine and legs), the sciatic nerve in the pelvis, [10] as well as other nerves such as the ...
