Onychomadesis is a loss of nail.[1] It typically occurs in one nail when due to trauma, or in multiple nails due to systemic disease.[1] The nail generally totally detaches with a new nail then appearing.[2]
It is a periodic idiopathic shedding of the nails beginning at the proximal end, possibly caused by the temporary arrest of the function of the nail matrix.[3]: 784 [4]: 660 One cause in children is hand, foot, and mouth disease.[5]

Cause
Onychomadesis can also occur if the nail is damaged or suffers a loss of blood supply; for example, due to a bruise. The nailbed turns black, and the nail drops off shortly afterwards. It takes around 6 to 12 months to regrow.
Outcome
This generally resolves without complication.
