Carpal Tunnel Syndrome (CTS) What is Carpel Tunnel Syndrome ? Carpal Tunnel Syndrome is a condition affecting the hand and wrist. The carpal tunnel is a space in the wrist surrounded by wrist bones and by a rigid ligament that links the bones together (see Figure 1). Figure-01 Through this small tunnel pass the flexing tendons of the fingers and thumb as well as the median nerve (see Figure 2). These tendons attach muscles to bones in the hand and transfer the movement of the fingers from muscles to bones. The median nerve carries signals from the brain to control the actions of the fingers and hand. It also carries information about temperature, pain and touch from the hand to the brain, and controls the sweating of the hand. The thumb, index, middle and ring fingers are under the control of the median nerve (see Figure 2).
