Carpal tunnel syndrome is a condition of the hands and fingers that occurs when the median nerve becomes compressed at the wrist. The median nerve extends from the forearm to the palm of the hand and controls feeling in all fingers except the little finger, as well as the palm side of the thumb. The median nerve also controls muscles in the hand that enable movement in the fingers and thumb.
The carpal tunnel is a slender passageway at the base of the hand that is comprised of bones and ligament. Within the carpal tunnel is where the median nerve is located, along with tendons. Swelling caused by aggravated tendons, or other inflammation within the tunnel, can cause the median nerve to compress and carpal tunnel to occur.
There are a few different outstanding factors that can lead to carpal tunnel syndrome. Some people have a hereditary predisposition in which their carpal tunnel is smaller than the average person’s, putting them more at risk for the condition. Trauma to the hand or wrist, such as a break or fracture, can cause swelling and contribute to carpal tunnel as well.
According to the National Institute of Neurological Disorders and Stroke, some other factors that can contribute to developing carpal tunnel syndrome include:
According to Womenshealth.gov, part of the U.S. Department of Health and Human Services, women are three times more at risk to develop carpal tunnel syndrome than men. This may be due to the fact that women in general have a much more narrow carpal tunnel than men, which creates a more constricted area for nerves and tendons to pass through. Another possible factor is that women undergo extreme hormonal changes throughout pregnancy and menopause that make them more likely to develop carpal tunnel.
A few different approaches can be taken to help prevent developing carpal tunnel syndrome.
Carpal tunnel syndrome has become increasingly more common in the United States. According to the Centers for Disease Control and Prevention, about 3.1% of employed adults aged 18 to 64 had carpal tunnel syndrome in 2010, and the percentage increased with each age group.
