(Greek: claw, nail; fingernails, toenails)
While acronyxes, or ingrown nails, can occur in the nails of the hands and feet, they usually exist most commonly with the toenails.
A more accurate description of an acronyx is that there is too much skin around the nail ("overgrown toeskin"), and so the nail itself is seldom the problem.
The most common place for acronyxes is in the big toe, however ingrowth can actually occur on any nail.
The length and width of fingernails were measured in patients with Marfan syndrome and in individuals without the syndrome
Marfan syndrome is a rare hereditary disorder of connective tissue. Affected people are tall, with long, thin limbs and spiderlike fingers (arachnodactyly).
The lens of the eye is dislocated, and many have glaucoma or detached retina. Heart muscle abnormalities and various malfunctions and malformations also occur; and rupture of the aorta is the most common cause of death.
Severity varies; affected individuals may die young or live essentially normal lives. The underlying abnormality cannot be cured, but some of the defects can be surgically corrected.
The condition occurs most frequently in the great toe, and is often caused by pressure from tight-fitting shoes.
Another common cause is improper cutting of the toenails, which should be cut straight across or with curved toenail scissors so that the sides are a little longer than the middle.
2. The perionychium or the tissue surrounding the nail, whether it be a fingernail or a toenail, including the tissue bordering the root and sides of the nail.
2. Abnormal softness of the fingernails and/or toenails.
A claw is a pointed curved nail on the end of each toe in birds, some reptiles, and some mammals.
2. Dystrophy of the nails in which they are abnormally thin and concave from side to side, with the edges turned up; it is sometimes seen in iron deficiency anemia.
2. An abnormal whiteness of the nails.
It has a variety of causes; including, total (leukonychia totalis) or only in spots (leukonychia punctata) or streaks (leukonychia striata).
