Carpal tunnel syndrome is a common condition that causes pain, numbness, and tingling in the hand and arm. Carpal tunnel syndrome occurs when the tunnel becomes narrowed or when tissues surrounding the flexor tendons swell, putting pressure on the median nerve.
If pressure on the median nerve continues, it can lead to nerve damage and worsening symptoms. To prevent permanent damage and when symptoms are severe or do not improve, surgery may be needed to make more room for the nerve. The goal of surgery is to increase the size of the tunnel in order to decrease pressure on the nerves and tendons that pass through the tunnel. This procedure is rarely revised, but we know that the risk of recurrence is 2-3%.
Revision surgery may be performed when carpal tunnel symptoms recur after a symptom-free period.
I have recently read an article about risk factors for revision surgery after carpal tunnel decompression. I think the picture below describes it very well. Enjoy
