Carpal tunnel syndrome involves the median nerve as it crosses the wrist. Here, it passes through a tunnel, formed by the ligaments of the wrist and tendons. Frequently, the ligaments will enlarge, or hypertrophy, for a variety of causes or for no known cause at all. These thickened ligaments will then compress and damage the median nerve. Symptoms appear usually

in the thumb, index and middle finger and the hand.
