Onychomadesis is a spontaneous loss of nail.[1] It typically occurs in one nail when due to trauma, or in multiple nails following a viral illness or some medicines.[1] The nail generally totally detaches from the base with a new nail appearing at the same time.[2]

It is caused by the temporary arrest of the function of the nail matrix.[3] The condition resolves without any specific treatment.[1]



It is a periodic idiopathic shedding of the nails beginning at the proximal end, caused by the temporary arrest of the function of the nail matrix.[1]


The condition generally resolves without complication.[1]
