Hook nail is a bowing of the nail bed due to a lack of support from the short bony phalanx (fingertip).[1]: 660
Signs and symptoms[edit]
The nail plate has volar concavity and a longitudinal hypercurvature. The patient may report discomfort, aesthetic impairment, and functional disability.[2]
Causes[edit]
Hook nail is caused by trauma to the hyponychium.[2] Hook nail is often seen after a fingertip amputation.[3]
Prevention[edit]
Some publications propose shortening the nail bed to the end of the bony support if it continues past the limit of the severed distal phalanx in order to prevent deformity.[4] Treatments intended to preserve length, such as replantation or flap reconstruction, should be used if the damage to the bone and soft tissue beneath the nail bed is too great.[5][6]
Treatment[edit]
Surgical options for hook-nail deformity include nail excision or finger shortening; alternatively, soft tissue reconstruction, bone grafting, nail recession, or partial toe transfer may be used to try to add some support to the nail bed.[3]
