DefinitionThis section has been translated automatically.
Hereditary, shortened, plump distal phalanx with shortened and widened nail plate and slight curvature of the distal nail edge. This results in a "tennis racket-like" appearance. In the majority of cases only one or both thumbs are affected. Racket nails of fingers 1-4 are rare. Coincidence with systemic scleroderma is described.

EtiopathogenesisThis section has been translated automatically.
Autosomal dominant inherited with varying expressiveness. Brachyonychia is also observed in onychophagia (nail biting). Ovenable, repeated severe cold traumas may be associated with secondary osteolysis and brachyonychia in appropriately predisposed individuals (tendency to Raynaud's symptoms or frostbite).
ManifestationThis section has been translated automatically.
Brachyonychia is the most common profile change of the nails. Women are 3 times more frequently affected than men.
Complication(s)This section has been translated automatically.
Reports of racket nails in hyperparathyroidism have been published.
