The term onychomadesis refers to complete separation of the nail from the proximal nail fold (matrix). It is usually due to some insult/injury to the nail matrix. Onychomadesis is, in a sense, a more severe form of Beau's lines. Specifically, when a Beau's line results in complete loss of continuity with the matrix, it is no longer a Beau's line but becomes onychomadesis.

Clinical

There is complete separation of the nail from the proximal nail fold (matrix) with persistent attachment to the nail bed and often, but not always, eventual shedding.

Causes (Modified from BJD 2015;172;592)

Treatment

No treatment is available once the separation has occurred. If there is an identifiable cause that can be eliminated, future separations may be prevented.
