Carpal Tunnelis a small canal made of bones and ligaments located under the skin on the top of wrist, connecting the tendons and nerves to the hand. Carpal Tunnel Syndrome is a disorder in which the canal is compressed due to various reasons, subsequently pinching the median nerve and causing pain, tingling/numbness, and paresthesia in the palm and fingers of the afflicted hand
Most common cause of Carpal Tunnel Syndrome is compression of carpal tunnel due to thickening of enveloping ligament. Others include fracture or dislocation in areas near carpal tunnel, or from previous injuries near carpal tunnel; edema from infection, inflammation, or injuries; increase of aponeurosis; and compression caused by tumors within the carpal tunnel.
The incidence rate is higher in women, obese, older, and diabetics. The condition may temporarily afflict women during pregnancy. Though both genders are prone to the condition, those of ages 40~60 are more likely to be affected, especially middle-aged women.
