Axillary nerve dysfunction
Definition
Axillary nerve dysfunction is a loss of movement or sensation of the shoulder because of nerve damage.
Alternative Names
Neuropathy - axillary nerveCauses
Axillary nerve dysfunction is a form of peripheral neuropathy. It occurs when there is damage to the axillary nerve, which supplies the deltoid muscles of the shoulder. A problem with just one nerve group, such as the axillary nerve, is called mononeuropathy.
Direct injury to the shoulder and pressure on the nerve can lead to axillary nerve dysfunction.
Conditions associated with axillary nerve dysfunction include:
- Fracture of the upper arm bone
- Pressure from casts or splints
- Improper use of crutches
- Shoulder dislocation
- Body-wide disorders that cause nerve inflammation
In some cases, no cause can be identified.
