What happens if thoracodorsal nerve is injured?

What happens if thoracodorsal nerve is injured?

An intact thoracodorsal nerve may also cause atrophy of the muscle, which can lead to shoulder and arm weakness that hampers numerous common movements, including standing up from a chair.

What is prefixed brachial plexus?

Hypothesis: A prefixed brachial plexus has been described as having a contribution to the plexus from C4 without a significant contribution from T1, while a postfixed brachial plexus has been described as having a T2 contribution without a significant contribution from C5.

What does the intercostal brachial nerve do?

The intercostobrachial nerve (ICBN) is a cutaneous nerve that provides sensation to the lateral chest, medial aspect of the upper arm, and the axilla.

What are thoracoabdominal nerves?

The thoracoabdominal nerves are derived from T7-T11 and form the inferior intercostal nerves. These nerves run along the internal obliques and the transversalis muscles. They then enter subcutaneous tissue to become the anterior cutaneous branches of the skin in the anterior abdominal wall.

Does thoracodorsal nerve innervate teres major?

The dorsal divisions of T6 to T12 provide the sensory innervation of the skin of the latissimus dorsi muscle. In about 13% of the population, thoracodorsal nerve innervates the teres major muscle.

How do you check for thoracodorsal nerve?

The thoracodorsal nerve may be identified as posterior and lateral to the lateral thoracic vein, two centimeters from the confluence of the lateral thoracic vein and the axillary vein. [2][3][4] The lateral thoracic vein is lateral to the lateral border of the pectoralis muscle.

How brachial plexus is formed?

The brachial plexus is formed by the anterior primary rami of C5 through T1 and provides sensory and motor innervation of the upper extremity. The brachial plexus is divided, proximally to distally into rami/roots, trunks, divisions, cords, and terminal branches.

What causes Klumpke’s palsy?

Klumpke paralysis is caused by an injury to the nerves of the brachial plexus that which may result during birth due to a a difficult delivery. This injury can cause a stretch injury (neuropraxia), scarring, or tearing of the brachial plexus nerves.

What causes long thoracic nerve damage?

Causes. Long thoracic nerve is more prone to injury due to its excessive length. Usually, injury to this nerve occurs due to trauma, direct blow to the rib area, over stretching or strenuous repetitive movements of the arms, and sustained bearing of excessive weight over the shoulder.

How is intercostal neuralgia treated?


  1. Intercostal nerve blocks: Injections of either a local anesthetic or a corticosteroid given around the affected intercostal nerves.
  2. Nonsteroidal anti-inflammatory drugs (NSAIDs): NSAID pain relievers, such as Advil (ibuprofen), and Aleve (naproxen) can help reduce inflammation and pain.

What is thoracoabdominal breathing?

breathing (T APB) characterized by the asynchrony of. the rib cage (RC) and the abdominal (AB) displace- ments as well as a diminished contribution of either. compartment to tidal volume (VT).
