Carpal Tunnel Syndrome - Causes

The Carpal Tunnel Syndrome causes are difficult to be determined as it is difficult to say that the primary cause of Carpal Tunnel Syndrome is whether due to work conditions or due to underlying medical problems.

Carpal tunnel syndrome can be found mostly in adult as most of the adult are working. CTS, then, is very likely to be associated with the work place whether or not it is actually caused by the work itself. Indeed, cases of work-related CTS are more. As for some studies, more than half of the Carpal Tunnal Syndrome cases are due to workplace factors and others which are few CTS cases are actually caused by the job conditions.

In a study, obesity, diabetes, hypothyroidism, and arthritis occurred in the majority of people who are having work-associated Carpal Tunnal Syndrome. Such conditions are main causes of carpal tunnel disorder.

In many cases of Carpal Tunnel Syndrome occur from a combination of factors, like predisposing medical condition exacerbated by work stress and psychological and social stressors. In many Carpal Tunnal Syndrome cases the cause of the disorder cannot be discovered.

Types of Causes of Carpal Tunnel Syndrome:

Work-Associated:

The main Carpal Tunnal Syndrome causes is the repetitive motion at workplace, which is increasing a lot. These cases contribute to half of the work associated illness and the Carpal Tunnel Syndrome.

They account for nearly half of all reported work-related illness, and Carpal Tunnal Syndrome is estimated to account for over 41% of the disorders caused due to repetitive motion. The key risk factors in the workplace that causes the Carpal Tunnel Syndrome.

  • Repetition
  • High force
  • Awkward joint posture
  • Direct pressure
  • Vibration, and
  • Prolonged constrained posture.

The main cause of the Carpal Tunnel Syndrome is the incorrect posture, especially in computer users and people working on other type of keyboard (Ergonomic Keyboard).

The rolling of the shoulders forward, rounding the lower back and thrusting the chin forward, shortens the neck and the muscles of the shoulder, there by compressing the nerves in the neck which ultimately have an effect on the wrist, fingers and the hand. But it is difficult to know the relation between the repetitive wrist, wrist and the Carpal Tunnel Syndrome.

The psychological factors like the deadlines, interpersonal factors and the job design at the workplace can also contribute for the inflammation of the carpal tunnel. These conditions are also main causes of the Carpal tunnal syndrome at the workplace.

Medical Problems:

The medical problems such as fracture or dislocation of bone can narrow the carpal tunnel, which in turn exerts pressure on the median nerve. Some other medical problems, like the rheumatoid arthritis, diabetes, and hypothyroidism, can also cause the inflammation in the carpal tunnel, which exerts pressure on the median nerve.

All these diseases are autoimmune diseases, which means that the body's own tissue are abnormally attacked by the body's immune system. Some experts believe that the initial stage of number of these diseases may be carpal tunnal syndrome.

A long-term hemodialysis and diseases such as multiple myeloma, Waldenstrom's macroglobulinemia, and non-Hodgkin's lymphoma, which cause a build-up of a waxy starchlike protein called amyloid in the bone and joint tissues can also cause Carpal Tunnel Syndrome.

Acromegaly, a disease that causes abnormally long bones, is a cause of CTS. In few cases it is suspected that a virus known as "human parvovirus " is developing CTS in both hands. The medications, which are administered to some of the cancer patients such as the interleukin-2, which effects the immune system can even, cause Carpal Tunnel Syndrome and even the anticlotting drugs such as warfarin can, cause CTS.

Hormonal Problems:

The preservation of fluid during pregnancy or hormonal changes associated with menopause can cause swelling and symptoms of carpal tunnel syndrome.

Genetically Inherited Problems:

The higher risk of the Carpal tunnel syndrome is reported in family having a history of this problem, which indicates that it is genetically inherited. Some researchers are particularly interested in abnormalities in certain genes that regulate myelin, a fatty substance that serves as insulation for nerve fibers. Some people may be born with abnormalities of the carpal bones.
