Thus, in humans, the nail of the index finger grows faster than that of the little finger; and fingernails grow up to four times faster than toenails. [ 10 ] In humans, fingernails grow at an average rate of approx. 3.5 mm (0.14 in) a month, whereas toenails grow about half as fast (approx. average 1.6 mm (0.063 in) a month). [ 11 ]
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.
Nail crumbling, and the lifting of the nail, could be signs of nail psoriasis. Nail psoriasis is a condition in itself, but it is also an independent risk factor for psoriatic arthritis .
Nail bracing is more conservative than surgery, but less widely used. Nail braces work by gently lifting the sides of the toenail and eventually retraining the nail to grow to a flatter shape over time. The total time needed for the nail to be reshaped is one full nail growth or about 18 months. [12]
But infections and other health conditions that can cause yellow nails tend to cause other noticeable symptoms, like pain, nail thinning or thickening, and lifting of the nail, the experts say.
[9] [10] The most reliable and applicable site for CRT testing is the finger pulp (not at the fingernail), and the cut-off value for the normal CRT should be 3 seconds, not 2 seconds. [ 2 ] To assess shock , central CRT, which is done by assessing capillary refill time at the sternum, rather than finger CRT, is more useful.
Onycholysis is a common medical condition characterized by the painless detachment of the nail from the nail bed, usually starting at the tip and/or sides. [1] On the hands, it occurs particularly on the ring finger but can occur on any of the fingernails. It may also happen to toenails. Onycholysis can occur in many conditions, including ...
Three phalanges are present on each finger and toe, with the exception of the thumb and big toe, which possess only two. The middle and far phalanges of the fourth and [citation needed] fifth toes are often fused together (symphalangism). [1] [2] The phalanges of the hand are commonly known as the finger bones. The phalanges of the foot differ ...
