Carpal tunnel syndrome wiki

It forms the passageway that transmits the median nerve and the tendons of the extrinsic flexor muscles of the hand from the forearm to the hand. The condition often require surgical division of the retinaculum to relieve the pressure upon the nerve. The carpal bones that make up the wrist form an arch which is convex on the dorsal side of the hand and concave on the palmar side. The groove on the palmar side, the sulcus carpi , is covered by the flexor retinaculum , a rigid band of fibrous tissue , thus forming the carpal tunnel. On the side of the radius , the flexor retinaculum is attached to the scaphoid bone , more precisely its tubercle , as well as the ridge of trapezium. On the ulnar side, it is attached to the pisiform and hook of hamate. The narrowest section of the tunnel is located a centimetre beyond the mid-line of the distal row of carpal bones where the sectional area is limited to 1. The tendons of the flexor digitorum superficialis and profundus pass through a common ulnar sheath, while the tendon of the flexor pollicis longus passes through a separate radial sheath. The mesotendon shared by these tendons is attached to the radial and palmar walls of the carpal tunnel. Ten structures pass through the carpal tunnel, most of them flexor tendons [2] not the muscles themselves :. The flexor carpi radialis one tendon is often incorrectly stated to travel within the carpal tunnel. More precisely, it travels within the fibers of the flexor retinaculum which forms the roof of the carpal tunnel, rather than running inside the tunnel itself. Movements in the wrist affect the shape and width of the carpal tunnel. The width decreases considerably during the normal range of motion in the wrist; and because the carpal bones move in relation to each other with every motion of the hand, the bony walls of the tunnel are not rigid.

When the symptoms and signs point to atrophy and muscle weakness more than numbness, consider neurodegenerative disorders such as Amyotrophic Lateral Sclerosis or Charcot-Marie Tooth. ISBN Compression of the median nerve at the carpal tunnel [1].

Carpal tunnel syndrome CTS is the collection of symptoms and signs associated with nerve compression of the median nerve at the carpal tunnel. As with most structural issues, it occurs in both hands, and the strongest risk factor is genetics. Other conditions can cause CTS such as wrist fracture or rheumatoid arthritis. After fracture, swelling, bleeding, and deformity compress the median nerve. With rheumatoid arthritis, the enlarged synovial lining of the tendons causes compression. The main symptoms are numbness and tingling in the thumb, index finger, middle finger and the thumb side of the ring finger.

Carpal tunnel syndrome is one of the most common hand conditions. It is caused by pressure on the median nerve in the carpal tunnel of the wrist. The carpal tunnel is a narrow passageway surrounded by bones and ligaments on the palm side of the hand. When the median nerve is compressed, symptoms can include numbness, tingling and weakness in the thumb and fingers. Wrist anatomy, health conditions and possibly repetitive hand motions can contribute to carpal tunnel syndrome. Tingling and numbness. Tingling and numbness may occur in the fingers or hand. Usually the thumb, index, middle and ring fingers are affected, but not the little finger. You might have a feeling like an electric shock in these fingers. These symptoms often occur while holding a steering wheel, phone or newspaper, or they may wake you from sleep.

Carpal tunnel syndrome occurs when there is a pinch or pressure on the median nerve located between the palm of the hand and the forearm. This can cause inflammation, pain, numbness, and tingling, as well as a feeling of pressure in the fingers, wrist, and arm. There are numerous reasons why someone would develop this syndrome, such as underlying health conditions, overuse of the wrist, injury to the area, or the anatomy of your wrist. By diagnosing and treating the syndrome, a person can reduce the symptoms.
