Carpal tunnel syndrome is a condition in which the median nerve in the carpal tunnel is compressed and causes numbness in the fingers. Carpal tunnel syndrome is caused by chronic injury to the median nerve in the wrist due to local fracture dislocation, ligament thickening, or swelling and enlargement of the tendons in the canal, resulting in a relative narrowing of the canal. Carpal tunnel syndrome, also known as delayed median nerve palsy, belongs to the “cumulative trauma disorder” and is common among office women aged 30 to 50 years old.
