Onychogryphosis or Ram's Horn Nails

Onychogryphosis or Ram's Horn Nails is a medical condition in which there is overgrowth or hypertrophy of the nails resulting in long, curved nails which resemble a claw or a ram's horn. The nails become thickened and deformed with discoloration of the nails with them appearing yellowish in color. The main cause is damage to the cells as a result of wearing ill-fitting or tight shoes, trauma or injury to the nail, infection of the nail, decreased blood supply to the nail; all these can cause Onychogryphosis or Ram's Horn Nails. Onychogryphosis can also occur from lack of hygiene and neglect of the nails, such as not trimming the nails regularly. The toenails are more commonly affected than the fingernails. Elderly people more commonly have this condition as the blood supply to the nails diminishes with age.

Very rarely, severe congenital Onychogryphosis or Ram's Horn Nails in all the twenty nail beds can occur. Congenital onychogryphosis of the fifth toe is quite common and is asymptomatic, so the patient rarely seeks treatment for it and is in fact not even aware of the problem.
