Signs and symptoms
The nail plate has volar concavity and a longitudinal hypercurvature. The patient may report discomfort, aesthetic impairment, and functional disability.[2]
Causes
Hook nail is caused by trauma to the hyponychium.[2] Hook nail is often seen after a fingertip amputation.[3]
Prevention
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
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]
