An asymptomatic defect of the thumb or great toe in which the distal phalanx and therefore nail as well is shorter and wider than normal, which is accompanied by a loss of the normal curvature; racquet nails may occur as an autosomal dominant ‘condition’ or in tertiary hypoparathyroidism due to erosion of the underlying bone
