An injury to the axillary nerve normally occurs from a direct impact of some sort to the outer arm, though it can result from injuring a shoulder via dislocation or compression of the nerve. The axillary nerve comes from the posterior cord of the brachial plexus at the coracoid process and provides the motor function to the deltoid and teres ...
The nerve lies at first behind the axillary artery, [4] and in front of the subscapularis, [1] and passes downward to the lower border of that muscle.. It then winds from anterior to posterior around the neck of the humerus, in company with the posterior humeral circumflex artery, [2] through the quadrangular space (bounded above by the teres minor, below by the teres major, medially by the ...
Injury of axillary nerve (axillary neuropathy) is a condition that can be associated with a surgical neck of the humerus fracture. It can also be associated with a dislocated shoulder [ 1 ] or with traction injury to the nerve, which may be caused by over-aggressive stretching or blunt trauma that does not result in fracture or dislocation.

The three main mechanisms of a stinger include receiving direct blows, extension, and compression of the brachial plexus, with most of the brachial plexus injuries being an extension-compression mechanism. A stinger is an injury that is caused by restriction of the nerve supply to the upper extremity via the brachial plexus. The brachial plexus ...
The axillary nerve is injured in 37% making it the most commonly injured structure with this type of injury. [14] Other common, associated, nerve injuries include injury to the suprascapular nerve (29%) and the radial nerve (22%). [14] Axillary nerve damage results in a weakened or paralyzed deltoid muscle and as the deltoid
Axillary nerve dysfunction is any disorder caused by damage to the axillary nerve. [1] The axillary nerve is a branch of the brachial plexus that innervates the deltoid and teres minor muscles. This nerve can be injured or damaged in a variety of ways - penetrating injury such as knife or gunshot wounds, surgical trauma, stretch injury (common ...
Inferior lateral cutaneous nerve of arm - Near blue "axillary" area, but actually branches from radial nerve. Most modern sources distinguish the superior and inferior, but some still include a single "lateral brachial cutaneous nerve". ) Intercostobrachial nerve (brown) Medial cutaneous nerve of arm (yellow) - labeled as "medial brachial ...
The surgery will help with nerve regeneration, providing guidance to the nerve sprouts on where to attach on the proximal side of the injury. Damaged nerve axons can reattach themselves after surgery. [3] Treatment of axonotmesis also consists of: Physical therapy or Occupational Therapy. Physical or Occupational therapy aims include: Pain relief
