Abstract
The fingernail is damaged and deformed by various causes such as crushing, laceration, avulsion injury, infection, tumor and personal habit. The growth disturbance of nail plate may be caused by systemic diseases or trauma without a direct injury of the fingernail and is usually found in accident. We experienced abnormal growth of nail plate in four patients with previous fractures of metacarpal bone. At about 8 weeks after trauma, a swelling and tenderness on the eponychium and a growth disturbance of affected nail plates occurred. All affected fingernails were treated with the nail extraction. The authors report four cases of growth disturbance of nail plates which obtained the satisfactory results by using the nail extraction.
