What is Carpal Tunnel Syndrome?
The carpal tunnel is a narrow passageway in the wrist made up of ligaments and bones.
The median nerve has to pass through this tightly spaced tunnel along with the tendons that connect the muscles of the forearm to the fingers. The median nerve is the main nerve for the wrist, hand, and fingers, and is the most common nerve effected in CTS.
CTS, is also known as median nerve entrapment because it occurs when swelling or irritation of the nerve or tendons in the carpal tunnel results in pressure on the median nerve. The median nerve controls sensations to the palm side of the thumb and fingers, as well as impulses to some small muscles in the hand that allow the fingers and thumb to move.
