What are the causes of the Carpal Tunnel Syndrome?
Occupational pathogenesis seems to be the most frequent cause for development of the Carpal Tunnel Syndrome. There seems to be an association between repetitive work activities, both in the presence (greater risk) or absence of great force. It has been proved that prolonged and/or repeated bending-extension movements (and bending of the fingers, to a lesser extent) cause increase in pressure inside the carpal tunnel, and repeated stretching of the nerves and tendons inside the carpal tunnel can lead to inflammation which reduces the size of the tunnel, thus leading to pinching of the median nerve. Systemic diseases can also be associated with the Carpal Tunnel Syndrome (for example diabetes mellitus, rheumatoid arthritis, myxedema, amyloidosis), apart from physiological conditions (such as pregnancy, use of oral contraceptives, menopause), trauma (repeated fractures of the wrist with articular deformities), arthritis and deforming arthrosis.
