Nerve damage in the elbow, often referring to damage of the ulnar nerve, occurs when the nerve is compressed, stretched, or irritated as it passes around the elbow. This can lead to various symptoms affecting the wrist and hand.
Understanding Ulnar Nerve Damage
The ulnar nerve is particularly vulnerable at the elbow because it is located close to the surface of the skin as it passes the elbow. This makes it susceptible to injury from external pressure or entrapment.
Common Causes of Ulnar Nerve Damage at the Elbow:
- Prolonged pressure: Resting the elbow on hard surfaces for extended periods can compress the ulnar nerve.
- Entrapment: The nerve can become trapped by surrounding tissues, such as ligaments or muscles, as it travels around the elbow.
Effects of Ulnar Nerve Damage:
Ulnar nerve damage can impair the function and sensation of the wrist and hand. This manifests as:
- Impaired movement: Weakness or difficulty in moving the wrist and fingers.
- Impaired sensation: Numbness, tingling, or pain, often experienced in the little finger and part of the ring finger.

Practical Insights
