Injury of axillary nerve

From WikiMD's Wellness Encyclopedia

Injury of Axillary Nerve is a medical condition that involves damage to the axillary nerve, a nerve in the human body that controls the deltoid muscles and skin sensation in the shoulder. It is often caused by shoulder dislocation or fractures of the humerus.

Causes[edit | edit source]

The axillary nerve can be injured due to various reasons. The most common causes include:

  • Shoulder dislocation: This is the most common cause of axillary nerve injury. The nerve can be damaged when the shoulder is dislocated, causing numbness and weakness in the shoulder.
  • Fracture of the humerus: The axillary nerve runs close to the humerus, so a fracture can easily damage the nerve.
  • Compression: The axillary nerve can be compressed by tumors, cysts, or other structures in the shoulder.

Symptoms[edit | edit source]

The symptoms of axillary nerve injury can vary depending on the severity of the injury. Common symptoms include:

  • Weakness or paralysis of the deltoid muscles
  • Loss of sensation in the shoulder
  • Pain or discomfort in the shoulder

Diagnosis[edit | edit source]

Diagnosis of axillary nerve injury is usually made based on the patient's symptoms and a physical examination. Additional tests such as electromyography (EMG) and nerve conduction studies may be used to confirm the diagnosis.

Treatment[edit | edit source]

Treatment for axillary nerve injury depends on the cause and severity of the injury. Options may include:

  • Physical therapy: This can help to strengthen the muscles and improve range of motion in the shoulder.
  • Surgery: In some cases, surgery may be needed to repair the damaged nerve or to remove any structures that are compressing the nerve.
  • Medication: Pain medication can be used to manage pain associated with the injury.

Prognosis[edit | edit source]

The prognosis for axillary nerve injury depends on the severity of the injury and the treatment received. With appropriate treatment, most people can make a full recovery.
