acronyx (s) (noun), acronyxes (pl)
An in-growing nail (on the hand or foot) or an in-grown fingernail or toenail: "An acronyx is a common form of toenail disease which is an often painful because the nail grows so that it cuts into one or both sides of the 'nail bed'."

"While acronyxes, or ingrown nails, can occur in the nails of the hand and feet, they usually exist most commonly with the toenails."

"A more accurate description is that an acronyx indicates that there is too much skin around the nail ("overgrown toeskin"), and so, the nail is seldom the problem."

"The most common place for acronyxes is in the big toe; however, ingrowth can actually occur on any nail."

acropathology (s) (noun), acropathologies (pl)
The study of diseases that affect the extremities; such as, the hands, fingers, feet, and toes: Because they are so frequently used, acropathology of the hands and fingers may require medical attention because they are susceptible to injury, including cuts, burns, bites, fractures, and even tendon injuries.
