Overview
Guyon’s canal is the passage through which the ulnar nerve crosses the wrist. Where the nerve is compressed within it, the result is pain or weakness in the hand.
Release divides the tissue or structures squeezing the nerve, which relieves the compression and improves hand function.
Risks and considerations
Releasing the ulnar nerve at the wrist carries the general risks of surgery and some specific to the nerve. As with any nerve decompression, surgery relieves the pressure but cannot reverse damage already done, so where numbness or weakness in the hand has been long-standing, recovery may be slow, partial or incomplete, and symptoms can persist or recur. Scar tenderness is common early on. Less common risks include injury to the nerve or its branches and to nearby vessels. What is realistic for a given degree of nerve involvement, and any underlying cause that needs treating as well, is discussed at the consultation.
How we quote
A quotation follows consultation, because what it costs depends on what the operation actually involves for you — the technique, the time in theatre, and whether anything is being addressed at the same time. We do not publish price lists and we do not quote before examining you.
