Beaus Lines Nails
The most common causes are local injury or exposure to severe cold both of which decrease the blood flow to the nail matrix.
Beaus lines nails. Beaus lines are horizontal or transverse depressions in the nail they can be seen in the fingernails thumbs toenails or all nails that may be confused with nail ridging. Additional interventions aside from the tinture of time are not required for treatment of beaus lines. Beaus lines are horizontal going across the nail and should not be confused with vertical ridges going from the bottom of the nail out to the fingertip.
The indentations can appear when growth at the area under the cuticle is interrupted by injury or severe illness. The beaus lines themselves represent a transient modification in the nail plate morphology and should grow out with continued production of nail plate. Conditions associated with beaus lines include uncontrolled diabetes and peripheral vascular disease as well as illnesses associated with a high fever such as scarlet fever measles mumps and pneumonia.
They result from a sudden interruption of nail keratin synthesis and grow distally with the nail plate. Most of the time however they look like a line across the nail. They usually develop when nail plate growth which begins in the nail matrix located under the cuticle is temporarily disrupted.
Beaus lines are a result of a variety of conditions ranging from minor to severe. This phenomenon was originally described in 1846 by the french physician joseph honore simon beau. You may be referring to beaus lines which are grooves that run horizontally across the nail plate.
First described by 19th century french physician joseph honore simon beau beaus lines are often described as depressions or grooves in the fingernails or toenails. Beaus lines are indentations that run across the nails. As the nail grows the beaus lines can disappear.
Beaus lines first described by french physician joseph honore simon beau in 1846 are horizontal grooved lines on a fingernail or toenail that run parallel to the lunula the half moon shaped whitish area that appears at the bed or proximal area of a nail. Beaus lines are horizontal transverse depressions in the nail plate that run parallel to the shape of the white moon shaped portion of the nail bed lunula seen at the nails origin. Beaus lines should also be distinguished from muehrckes lines of the fingernails.
These vertical lines are usually a natural consequence of aging and are harmless.
