Carpal tunnel syndrome (CTS) is a condition that occurs when the median nerve is squeezed within its passage between the wrist bones and the transverse carpal ligament as it moves toward the hand. The median nerve provides sensation to half of the palm on the thumb side of your hand, the thumb, the first two fingers and half of the third, as well as the tips and the top half of the back of the same fingers. The nerve also supplies the muscles on the front of the forearm, wrist, and thumb. These muscles work to bend the wrist, turn the palm down, and move the thumb.
