Carpus is a word derived from the Greek word karpos, which means "wrist." The wrist is surrounded by a band of fibrous tissue that normally functions as a support for the joint. The tight space between this fibrous band and the wrist bone is called the carpal tunnel. The median nerve passes through the carpal tunnel to receive sensations from the thumb, index, and middle fingers of the hand. Any condition that causes swelling or a change in position of the tissue within the carpal tunnel can squeeze and irritate the median nerve. Irritation of the median nerve in this manner causes tingling and numbness of the thumb, index, and the middle fingers - a condition known as "carpal tunnel syndrome." This term was first used in 1939, but the scientists had started to investigate the problem only in the 1960s when a number of serious researches dedicated to this disease were held. Problems that can occur in carpal tunnel syndrome include: * Pain
Shiel (2010) writes that for most patients, the cause of their carpal tunnel syndrome is unknown, but there are several conditions that can cause the syndrome – obesity, pregnancy, arthritis, diabetes and trauma. Tendon inflammation resulting from repetitive work, such as uninterrupted typing, can also cause carpal tunnel symptoms. Carpal tunnel syndrome from repetitive maneuvers has been referred to as one of the repetitive stress injuries. Some rare diseases can cause deposition of abnormal substances in and around the carpal tunnel, leading to nerve irritation. These diseases include amyloidosis, sarcoidosis,multiple myeloma, and leukemia. What are the main carpal tunnel syndrome symptoms?
People with carpal tunnel syndrome initially feel numbness and tingling of the hand in the distribution of the median nerve (the thumb, index, middle, and part of the fourth fingers). These sensations are often more pronounced at night and can awaken...
