Osteoporosis in the hand or foot [Described 1900. After Paul Hermann Martin Sudeck (1866-1938), German surgeon.]
A disorder of the sympathetic nervous system, which involves the network of nerves located along the spinal cord. These nerves control certain functions including those associated with the working of the blood vessels and sweat glands. Sudeck atrophy is also called posttraumatic osteoporosis, which is part of reflex sympathetic dystrophy. The disorder most commonly affects women older than 50, but may affect anyone. Sudeck atrophy often occurs following an injury (such as a forearm fracture) or heart attack or stroke, but in many cases, the cause is unknown. The symptoms include swelling and severe pain that may be experienced as a burning sensation usually in the hand or foot, but also possibly in the knee, hip, shoulder, or other area of the body. The skin in the affected area may become thin or shiny, and there may be a localized increase in perspiring and hair growth. As Sudeck atrophy progresses, the pain may be accompanied by weakness and wasting, or dystrophy, in the affected region. There may also be contracture, which is when the muscle becomes shortened and immobilized.
Enlargement and reduced functionality of a hand or foot following a fracture or another injury. The approach to treatment involves raising the affected hand or foot, mild exercises, and the application of heat. Typically, complete recuperation occurs within approximately four months.
