Axillary nerve dysfunction is a form of peripheral neuropathy. It occurs when there is damage to the axillary nerve. This is the nerve that helps control the deltoid muscles of the shoulder and the skin around it. A problem with just one nerve, such as the axillary nerve, is called mononeuropathy.
What happens when axillary nerve is damaged?
Axillary nerve dysfunction is nerve damage that can lead to a loss of movement or sensation in the shoulder. Conditions associated with axillary nerve dysfunction include fracture of the humerus (upper arm bone), pressure from casts or splints, and improper use of crutches.
Where is the axillary nerve in the deltoid?
The axillary nerve is found inferior to the capsule of the shoulder joint, and it sends a small branch to this joint. The axillary nerve then winds medial to the surgical neck of the humerus, and is typically in contact with this part of the bone.
What muscles does the axillary nerve?
Axillary nerve (ventral rami of C5 & C6) arises from the posterior cord of brachial plexus giving muscular branches to teres minor & deltoid. It also supplies the shoulder joint and the skin over it [1].
What type of nerve is axillary nerve?
circumflex nerve The axillary nerve or the circumflex nerve is a nerve of the human body, that originates from the brachial plexus (upper trunk, posterior division, posterior cord) at the level of the axilla (armpit) and carries nerve fibers from C5 and C6. …

How do you release an axillary nerve?
What are the symptoms of axillary nerve damage?
What are the symptoms of axillary nerve dysfunction?
- feel numbness or tingling in the shoulder region.
- have weakness in the shoulders.
- have problems with normal physical activities, such as lifting your arms above your head.
- have difficulty lifting objects.
How long does it take axillary nerve to heal?
Full recovery occurs 85% to 100% of the time with conservative management within 6 to 12 months. Muscle weakness due to the axillary nerve lesion may recover spontaneously as the tissues from the shoulder dislocation heal.
Can an axillary nerve be repaired?
In many cases, axillary nerve injury will heal on its own. This may take several months. During that time it is important to do physical therapy to maintain flexibility across the shoulder joint. If after several months, the weakness does not improve, then surgery to treat the nerve injury is indicated.
What is the function of the axillary nerve?
The axillary nerve’s primary purpose is to supply nerve function to the shoulder joint and three muscles in the arm, but it also innervates some skin in that region, as well.
How do you test the axillary nerve?
Where is a deltoid nerve located?
shoulder Deltoid – situated at the superior aspect of the shoulder. It performs abduction of the upper limb at the glenohumeral joint and is innervated by the anterior terminal branch of the axillary nerve.
What is the axillary?
The axilla is an anatomical region under the shoulder joint where the arm connects to the shoulder. It contains a variety of neurovascular structures, including the axillary artery, axillary vein, brachial plexus, and lymph nodes.
What promotes nerve regeneration?
Summary: Researchers have shown that treatment using gene therapy leads to a faster recovery after nerve damage. By combining a surgical repair procedure with gene therapy, the survival of nerve cells and regeneration of nerve fibers over a long distance was stimulated.
Can shoulder nerve damage be repaired?
There’s a misconception that nerves can’t regrow. They can. But the key to success in treating these injuries is speed. Surgical techniques to transfer nerves from other parts of the body to heal torn ones in the plexus have a window of only a few months to work, and recovery takes months to years.
How do you fix shoulder nerve entrapment?
Managing a pinched nerve in the shoulder
- Apply cloth-covered ice packs to the neck and shoulder blade area over a period of up to 48 hours after the pain began. …
- Sleep with a pillow designed to support the neck. …
- Take anti-inflammatory or pain-relieving medications.
How do you test for shoulder nerve damage?
EMG: An electromyogram often is considered when there is possible nerve damage as a root to your shoulder pain and shoulder weakness. The test that uses electrical activity detects the muscles response to a stimulus.
Will shoulder MRI show nerve damage?
MRIs show the presence of any masses (tumors, cysts) and condition of the soft tissues (labrum, rotator cuff, muscle atrophy). An MRI can even show the nerve pathway and any areas of restriction.
What does nerve damage in shoulder feel like?
A pinched nerve may also leave you with a feeling of “pins and needles” in your shoulder. The joint may also feel numb or weak when you try to lift something. In some cases, symptoms extend from the shoulder down the arm to the hand.
Where does the axillary nerve terminate?
In the posterior scapular region, the axillary nerve terminates by dividing into two branches: – Posterior terminal branch – Provides motor innervation to the teres minor muscle, and innervates the skin over the inferior part of the deltoid.
Can you get paralyzed from a pinched nerve?
Lumbar radiculopathy is pressure on one of the nerve roots in your lower back. It can cause hip pain and sciatica, or shooting pain in your leg. Incontinence, sexual dysfunction, or paralysis can also occur in severe cases.
Is nerve injury permanent?
In many instances, nerve damage cannot be cured entirely. But there are various treatments that can reduce your symptoms. Because nerve damage is often progressive, it is important to consult with a doctor when you first notice symptoms. That way you can reduce the likelihood of permanent damage.
What is the root value of axillary nerve?
Origin and root value : Axillary nerve is a branch of posterior cord of brachial plexus. Its root value is C5,C6 segments of spinal cord.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
