Neuropathy - axillary nerve
Axillary nerve dysfunction is nerve damage that leads to a loss of movement or sensation in the shoulder.
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 and the skin around it. A problem with just one nerve, such as the axillary nerve, is called mononeuropathy.
The usual causes are:
Entrapment creates pressure on the nerve where it passes through a narrow structure.
The damage may destroy the myelin sheath that covers the nerve, or part of the nerve cell (the axon). Damage of either type reduces or prevents the movement of impulses through the nerve.
Conditions that can lead to axillary nerve dysfunction include:
In some cases, no cause can be found.
