[1]: 660 The nail plate has volar concavity and a longitudinal hypercurvature.
The patient may report discomfort, aesthetic impairment, and functional disability.
[3] 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] 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.
