What is an ulnar nerve decompression at the elbow?
The Ulnar nerve is a nerve which supplies feeling and strength to a portion of the hand and forearm. It may become compressed or trapped as it passes past the elbow. Ulnar nerve decompression at the elbow is performed to free up the nerve. It involves a small cut around the elbow, to free up the compressed nerve.
This procedure will require an anaesthetic.
