Onycholysis Nails

 

Onycholysis is the painless separation of the nail from the nail bed. This is a common problem. It can be a sign of skin disease, an infection or the result of injury, but most cases are seen in women with long fingernails.

Discoloration underneath the nail may occur as a result of secondary infection.
Spontaneous separation of the nail plate starts at the distal free margin and progresses proximally. Less often, nail plate separation may begin at the proximal nail (base) and extend to the free edge. The nail plate is separated from underlying and/or lateral supporting structures.

Nail plate separation can be confined to the nail's lateral borders (rare).
