OverviewConditions associated with axillary nerve dysfunction include fracture of the humerus (upper arm bone), pressure from casts or splints, and improper use of crutches. Other causes include systemic disorders that cause neuritis (inflammation of nerves). If the cause of the axillary nerve dysfunction can be identified and successfully treated, there is a possibility of full recovery. The extent of disability varies. The worst problem most often is shoulder weakness.
