Overview
Onychogryposis is a thickening and increase in curvature of the nail. An affected nail may have many grooves and ridges, is usually brownish in color, and grows more quickly on one side than on the other.

Associated Conditions

- Chronic chemical damage
- Lichen ruber

Causes
Common Causes
It is usually the result of injury to the matrix, sometimes coupled with a long term fungal infection, which causes the nail to grow more thickly. It may be partially hereditary and is caused by neglect. It is most commonly seen in the great toe but may be seen in other toes as well as the fingernails. Unusual thickness is also associated with circulation problems.
Causes in Alphabetical Order
Natural History, Complications and Prognosis
The thick curved nail is difficult to cut, and often remains untrimmed, exacerbating the problem. Long, untreated nails due to onychogryphosis are an often a hidden cause of disability among the elderly.
