During open carpal tunnel release surgery, the transverse carpal ligament is cut. This releases pressure on the median nerve and relieves the symptoms of carpal tunnel syndrome.
An incision is made at the base of the palm of the hand. This allows the doctor to see the transverse carpal ligament. After the ligament is cut, the skin is closed with stitches. The gap where the ligament was cut is left alone. Over time, it fills up with scar tissue.
Most people who have this surgery don't need to stay in the hospital. It is usually done with local anesthetic, and you can go home on the same day.
Open carpal tunnel surgery is considered when:
Most people who have surgery for carpal tunnel syndrome have fewer or no symptoms of pain and numbness in their hand after surgery.
In rare cases, the symptoms of pain and numbness may come back. (This is the most common complication.) Or you may have short-term loss of strength when you pinch or grip an object. This is because the transverse carpal ligament was cut.
If the thumb muscles have been severely weakened or wasted away, your hand strength and function may be limited even after surgery.
Both endoscopic and open carpal tunnel release have benefits and risks. Studies don't show that one procedure is better than the other in the long term.
