Abstract

|
Brachyonychia or racquet nail is a condition that the width of the nail plate is greater than the length. It may occur in isolation or in association with shortening of the terminal phalanx. Racquet nail is usually inherited as an autosomal dominant trait due to premature obliteration of the epiphyseal line. All the fingers may rarely be involved. We describe one family of brachyonychia showing typical autosomal dominant pattern of inheritance, in which the father had short nails on almost all fingers and his 14-year-old son showed bilateral racquet thumb.
