A procedure in which an arm or a leg is made longer. Its bone is divided in two and new bone forms in the gap between the ends.
An orthopaedic procedure in which the length of a limb, usually a leg, is increased. The bone is surgically divided and slowly stretched in a special frame. The operation is usually done on people with unequal leg lengths as a result of injury, or from paralysis in childhood. Exceptionally, it may be done in both legs to help people of short stature.
