Racquet nails usually occur on one or both thumbs, but may appear on all fingers and toes. It may be genetic, inherited as an autosomal-dominant trait,[2]: 786 or acquired. Genetic disorders associated with racquet nail include Larsen syndrome, Brooke–Spiegler syndrome, Rubinstein–Taybi syndrome, Hajdu–Cheney syndrome, cartilage–hair hypoplasia, pycnodysostosis, acrodysostosis, and brachydactyly type D.[4]
Acquired racquet nail is associated with acroosteolysis and psoriatic arthropathy.[4] Acquired racquet nail may also be diagnostic of bone resorption in hyperparathyroidism.[5]
Racquet nail often presents with other nail conditions such as onycholysis, koilonychia, pachyonychia, Muehrcke's lines, leuconychia, and half-and-half nails.[5] Cosmetic surgery can be used to improve the appearance of the nails.[4]
