The free margin (margo liber) or distal edge is the anterior margin of the nail plate corresponds to the abrasive or cutting edge of the nail. [3] The hyponychium (informally known as the "quick") [6] is the epithelium located beneath the nail plate at the junction between the free edge and the skin of the fingertip. It forms a seal that ...
Beau's lines should also be distinguished from Mees' lines of the fingernails, which are areas of discoloration in the nail plate. As the nail grows out, the ridge in the nail can be seen to move upwards until it reaches the fingertip. When it reaches this point the fingertips can become sore for a few days as the nail bed is exposed by the ...
Parakeratosis pustulosa is most commonly seen in children as an eczematoid eruption near the free margin of the nail that extends to the dorsal nail fold. Under the free margin of the nail, hyperkeratosis causes the nail plate to pull up and results in a deformity that resembles a gaping toecap separated from the sole at the seam. Pitting and ...
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).
Muehrcke's lines were described by American physician Robert C. Muehrcke (1921–2003) in 1956. In a study published in BMJ, he examined patients with known chronic hypoalbuminemia and healthy volunteers, finding that the appearance of multiple transverse white lines was a highly specific marker for low serum albumin (no subject with the sign had SA over 2.2 g/dL), was associated with severity ...
Some publications propose shortening the nail bed to the end of the bony support if it continues past the limit of the severed distal phalanx in order to prevent deformity. [4] Treatments intended to preserve length, such as replantation or flap reconstruction, should be used if the damage to the bone and soft tissue beneath the nail bed is too ...

The blood puts pressure to the nailbed causing pain which can be throbbing in quality and disappears when the pressure on the nail bed is relieved. [2] Subungual hematomas typically heal without incident, though infection may occur. The pressure of the blood blister may cause separation of nail plate from the nail bed (onycholysis), but the ...
