Carpal tunnel syndrome is a common condition characterized by hand symptoms (pain, sensitivity disorders and decreased strength). It results from compression of the median nerve in the wrist and is favoured by the repetition of certain movements or postures of the hand as well as by certain diseases.
WHAT IS CARPAL TUNNEL SYNDROME?
Carpal tunnel syndrome refers to disorders related to compression of the median nerve as it passes through the carpal tunnel at the wrist.
The median nerve is a nerve that is both sensitive and motor. It controls the sensitivity of part of the hand and arm, and allows movements with the hand and wrist. It descends into the forearm, passes through the carpal tunnel at the wrist, and is distributed in the first four fingers: the thumb, index finger, middle finger (or middle) and part of the ring finger.
If the nerve is compressed, the nerve impulse scans hardly pass and the symptoms appear: tingling, impaired sensitivity and decreased strength.
The carpal tunnel is a tunnel located on the anterior side of the wrist. It is limited backwards and on the sides by the wrist bones (carp) and forward by the annular ligament of the carp. It contains the nine tendons of the flexor muscles of the fingers and the median nerve.
