The carpal tunnel runs from the base of the hand through the wrist. Compression of the median nerve, which passes through the carpel tunnel, may cause symptoms that range from tingling in the fingers to pain radiating up the arm.
Fractures of the hand can occur in either the small bones of the fingers (phalanges) or the long bones (metacarpals). They can result from a twisting injury, a fall, a crush injury, or direct contact in sports.
Nerves are fragile and can be damaged by pressure, stretching, or cutting. Injury to a nerve can stop signals to and from the brain, causing muscles not to work properly, and a loss of feeling in the injured area.
