An ingrown nail, also known as onychocryptosis (from Greek: ὄνυξ (onyx) 'nail' and κρυπτός (kryptos) 'hidden') is a common form of nail disease.It is an often painful condition in which the nail grows so that it cuts into one or both sides of the paronychium or nail bed.
[citation needed] Some physicians will not perform a complete nail avulsion (removal) except under extreme circumstances. In most cases, these physicians will remove both sides of a toenail (even if one side is not currently ingrown) and coat the nail matrix on both sides with a chemical or acid (usually phenol) to prevent re-growth.
The cause is poorly understood due to a lack of research, but genome-wide scans indicate that it is a heritable trait, and could be autosomal dominant. [1] However, the wide variance in the size and structure of the accessory nail indicates that the trait may not follow a Mendelian pattern of inheritance, and may instead be a complex trait affected by multiple genes with minor genetic effects.
Lindsay’s nails cause the color of the nail bed to look half white and half red or brown, whereas Terry’s nails cause the nail bed to look mostly white or washed-out, per Cleveland Clinic ...
The nail wall (vallum unguis) is the cutaneous fold overlapping the sides and proximal end of the nail. The lateral margin (margo lateralis) lies beneath the nail wall on the sides of the nail, and the nail groove or fold (sulcus matricis unguis) are the cutaneous slits into which the lateral margins are embedded.

The hyponychium (IPA: / ˌ h aɪ p oʊ ˈ n ɪ k i ə m /) [1] [2] is the area of epithelium, particularly the thickened portion, underlying the free edge of the nail plate on the nail. Its proximal border is immediately distal to distal limit of nail bed—a.k.a. the onychodermal band (the line along the interface of the nail bed and the nail ...
Beau's lines are deep grooved lines that run from side to side on the fingernail or the toenail. [1] They may look like indentations or ridges in the nail plate. [2]: 657 This condition of the nail was named by a French physician, Joseph Honoré Simon Beau (1806–1865), who first described it in 1846.
The lunula (pl.: lunulae; from Latin 'little moon') is the crescent-shaped whitish area of the bed of a fingernail or toenail.. In humans, it appears by week 14 [1] of gestation, and has a primary structural role in defining the free edge of the distal nail plate (the part of the nail that grows outward).
