The human wrist is surrounded by a band of fibrous tissue and its primary function is to lend support for the joint.
The carpal tunnel is the space between this fibrous band and the wrist bone and the median nerve passes through a tunnel at the base of the wrist.
Carpal tunnel syndrome (CTS) is caused by compression of the median nerve at this point.
Symptoms of CTS include numbness and tingling of the hand around the thumb, index, middle, and ring fingers.
Other symptoms include burning sensation, reduced grip strength, muscle atrophy, and radiating pain from the hand to the forearm.
CTS is caused by conditions like diabetes, pregnancy, hypertension, fracture, or trauma to the wrist. Sometimes repeated motion of the wrist can lead to symptoms of CTS.
