Abstract
Hook-nail deformity is frequently seen after a fingertip amputation, whether or not flap reconstruction has been done. It is more frequent if the bony support is missing. The deformity results in esthetic and functional impairment which can lead to complete finger amputation. Correction is surgical, but is difficult and surgical series are small. Soft-tissue flap augmentation is simple, but does not add a bony support. Bone augmentation using local flaps is limited by the small size of the distal phalanx remnant. Toe transfer is more logical but, as it is a highly demanding technique, only a few cases have been published. The present study sought to review all the published techniques and their results, to help the reader choose the one best suited to their patient.
