The Hand

Applying a heat treatment or cold treatment is a common method for treating injuries, stiffness, swelling and pain.

When the skin comes in contact with something hot, it may be damaged, with death of cells in the skin. The severity of the injury depends on the intensity of the heat and the length of time that it is in contact with either heat or certain chemicals.

A jammed finger is common in sports but may also occur during regular daily activities. Even if the injured finger looks normal and can move normally, it may require medical treatment.

A “jersey finger” refers to a rupture of the flexor tendon, which is the tendon that bends the fingertip down. Its name comes from football athletes who have gripped the jersey of an opposing player who is trying to get away.

Kienbock’s disease is also known as avascular necrosis (AVN) of the lunate. The lunate is one of the eight small bones in the wrist. In this condition, the lunate bone loses its blood supply, leading to death of the bone.

In a joint replacement, the abnormal structures of the joint are removed and replaced. These structures are bone, cartilage, and synovium.

A mallet finger is a deformity of the finger. It occurs when the tendon that straightens the finger (the extensor tendon) is damaged at the fingertip.

Hand bones are called metacarpals. The finger bones are called phalanges. The metacarpophalangeal joint (MCP joint), or knuckle, is where the finger bones meet the hand bones. At the MCP joint, the fingers can move in multiple directions.

A nail bed injury can be very painful and prevent you from using your fingers; however, these injuries are treatable.

Nerve repair is required after a nerve is injured in such a way that it will not recover on its own. Nerves are bundles of fibers that carry messages between the brain and the rest of the body.
