Axillary nerve palsy

Axillary Nerve Palsy

Axillary nerve palsy (/æksɪˌlɛri nɜːrv pɔːlzi/), also known as circumflex nerve palsy, is a medical condition characterized by damage to the axillary nerve, leading to a loss of movement or sensation in the shoulder area.

Etymology

The term "axillary" is derived from the Latin word "axilla", meaning "armpit", while "palsy" comes from the Old French "paralisie", meaning "paralysis".

Symptoms

The primary symptoms of axillary nerve palsy include:

• Weakness or inability to lift the arm
• Numbness or decreased sensation in the shoulder area
• Muscle atrophy in severe or prolonged cases

Causes

Axillary nerve palsy is most commonly caused by shoulder dislocation or fractures of the humerus. It can also occur as a result of direct trauma to the axillary nerve, or due to nerve compression from prolonged use of crutches or other devices.

Diagnosis

Diagnosis of axillary nerve palsy typically involves a physical examination, patient history, and may include imaging tests such as an MRI or nerve conduction study.

Treatment

Treatment for axillary nerve palsy often involves physical therapy to restore strength and mobility to the shoulder. In some cases, surgery may be required to repair the damaged nerve.
