What is carpal tunnel syndrome?
Running from your neck down your arm and into your hand is the median nerve, which controls feeling and movement in your thumb and the first 3 fingers of your hand. On its way to your fingers and thumb, your median nerve, and 9 tendons, pass through a small space in your wrist called the carpal tunnel.
Below the carpal tunnel are the small bones of your wrist and above is a thick ligament (the carpal ligament). If your median nerve gets squeezed between the bones and the carpal ligament, it can cause pain, numbness, tingling and weakness in your fingers.
What causes it?
Compression of your carpal tunnel nerve can be caused by swelling (especially of the flexor tendons) due to repetitive movements. Other causes include conditions that reduce blood flow to your hands like obesity, rheumatoid arthritis, gout and diabetes.
A past injury to your wrist can also contribute to carpal tunnel syndrome.
What is carpal tunnel surgery?
Carpal tunnel surgery relieves the symptoms by cutting the ligament that’s pressing on the nerve. There are 2 ways of doing this:
- Keyhole carpal tunnel release surgery – your surgeon makes 1 or 2 small incisions and uses a thin, flexible tube with a light on the tip to see the area, and then guide a scalpel to cut the ligament. This is also known as endoscopic carpal tunnel surgery.
- Open carpal tunnel release surgery – your surgeon uses a larger incision to see the area directly and cut the ligament.
