Ulnar nerve entrapment is a condition where the ulnar nerve becomes physically trapped or pinched, resulting in pain, numbness, or weakness.

The nerve is particularly vulnerable to injury when there has been a disruption in the normal anatomy.

The most common site of ulnar nerve entrapment is at the elbow, followed by the wrist. Chronic compression or repetitive trauma can cause persistent problems.

How is ulnar nerve compression treated?

Sometimes the symptoms settle on their own, with analgesia and modification of activity – avoidance of repetitive elbow movements and direct pressure over the inside of the elbow. When this does not occur, surgery to release the trapped nerve may be indicated.

Ulnar nerve compression surgery

This operation is performed frequently, and is known as an ulnar neurolysis. It involves making a small incision, or cut, over the inside of the elbow.

Using magnification, your surgeon will carefully divide the band of tissue which is constricting the nerve. Sometimes there is significant scar tissue around the nerve, and this is also divided.
