Carpal tunnel syndrome is a condition that causes numbness, tingling and other symptoms in the hand and arm. Carpal tunnel syndrome is caused by a compressed nerve in the carpal tunnel, a narrow passageway on the palm side of your wrist. The anatomy of your wrist, health problems and, possibly, repetitive hand motions can contribute to carpal tunnel syndrome.
Carpal tunnel syndrome symptoms usually start gradually. The first symptoms often include numbness or tingling in your thumb, index and middle fingers that comes and goes. Carpal tunnel syndrome also may cause discomfort in your wrist and the palm of your hand.
During carpal tunnel release, a surgeon makes an incision in the palm of your hand over the carpal tunnel ligament and cuts through the ligament to relieve pressure on the median nerve. The surgery may be done by making one incision on the palm side of the wrist or by making several small incisions.
