This gryphosis can be mistaken for a fungal infection of the nail and treated with expensive drugs inappropriately.

Onychogryphosis a disorder that is characterized by the hypertrophy and excessive curving of the nails, also known as hypertrophy that may produce nails resembling claws or a ram's horn, possibly caused by trauma or peripheral vascular disorders, but most often secondary to neglect and failure to cut the nails for extended periods of time and is most commonly seen in the elderly.

Onychogryphosis may rarely occur as a development abnormality but is usually acquired, its irregular surface is marked by transverse striations, sometimes this nail is oyster like. Appears in cases of self-neglect and is often seen in tramps and senile dementia. Idiopathic forms are acquired and hereditary.

Onychogryphosis is often caused by trauma or repetitive micro trauma to the nail or matrix,” says Dr. Robbins. In toenails, this can be caused by something as common as ill-fitting shoes, she says. In extraordinary cases, such as the fingernails pictured on page 94, damage to the ulnar and median nerves is the initial cause. Those nerves supply impulses to the fingers and without the proper nerve supply, the nails worsen, especially with extended neglect.

    Nail thickening.

  • Nail curving.


Onychogryphosis is usually detected by physical observation. The sight of a thickened, claw-shaped curved nail is generally enough for a medical professional to diagnose the condition.
