Mononeuropathy is damage to a single nerve or nerve group, which results in loss of movement, sensation, or other function of that nerve.

Neuropathy; Isolated mononeuritis

Mononeuropathy is a type of damage to nerves outside the brain and spinal cord (peripheral neuropathy).

Mononeuropathy is most often caused by injury, although body-wide (systemic) disorders may cause isolated nerve damage.

Long-term pressure on a nerve due to swelling or injury can result in mononeuropathy. The covering of the nerve (myelin sheath) or part of the nerve cell (the axon) may be damaged. This damage slows or prevents signals from traveling through the damaged nerves.

Mononeuropathy may involve any part of the body. Some of the common forms of mononeuropathy include:

• Axillary nerve dysfunction
• Common peroneal nerve dysfunction
• Carpal tunnel syndrome
• Cranial mononeuropathy III; compression type
• Cranial mononeuropathy III; diabetic type
• Cranial mononeuropathy VI
• Cranial mononeuropathy VII
• Femoral nerve dysfunction
• Radial nerve dysfunction
• Sciatic nerve dysfunction
• Ulnar nerve dysfunction
