TL;DR: The hook nail deformity is a relatively common complication after fingertip amputation and can be corrected or prevented with a carefully performed surgical procedure.
Abstract: The hook nail deformity is a relatively common complication after fingertip amputation. It can be corrected or prevented with a carefully performed surgical procedure. The nail plate is removed. The redundant nail bed that is folded over the tip of the terminal phalanx is carefully removed with an additional 2 mm that is supported by the terminal phalanx so that wound healing will not draw the nail bed over the tip of the phalanx again. The fingertip is then resurfaced by a V-Y advancement flap, with precautions taken to avoid all tension in the flap.

TL;DR: The hook-nail deformity is a relatively common problem after fingertip amputations and can be quite disabling but can be corrected by a carefully planned operation.
Abstract: The hook-nail deformity is a relatively common problem after fingertip amputations. It is usually ignored but can be quite disabling. This deformity can be corrected by a carefully planned operation. Most of the curved nail plate is removed, the pulp is reflected from the distal phalanx out to a normal contour, and then the full thickness of the nail bed is elevated off the distal phalanx and splinted by multiple small Kirschner pins in a straight position. The defect created is covered with a cross finger flap.

TL;DR: Although not a panacea for all distal fingertip amputations, the antegrade-flow homodigital neurovascular pedicle flap offers a good ratio of advantages to disadvantages.
Abstract: Fingertip amputations through the distal 50% of the nail matrix usually create a finger that is best served by maintaining length. When the amputation is more proximal than this, revision with ablation of the small residual nail unit may provide greater overall patient satisfaction. When amputations in the distal 50% of the nail matrix are transverse or short oblique in orientation, a flap of some kind is needed to restore the contact surface of the pulp. Many alternative reconstructive strategies are possible but have inherent limitations that detract from the quality of the final result. Inadequate padding, lack of sensibility, excessive tension, hook nail deformity, poor durability, and donor site morbidity are but some of the considerations. Although not a panacea for all distal fingertip amputations, the antegrade-flow homodigital neurovascular pedicle flap offers a good ratio of advantages to disadvantages. As with all flaps, knowledge and execution of the details largely determine the outcome.

TL;DR: The transfer of direct-flow island flaps, from the same finger, causes minimal morbidity on the donor site and appears to be a safe method, providing satisfactory functional and aesthetic results in the reconstruction of pulp defects.

TL;DR: Patients presenting 18 hook-nail deformities have been treated by the advancement of a homodigital island flap with results considered good or excellent in seven cases, fair in seven and poor in four.
Abstract: Sixteen patients presenting 18 hook-nail deformities have been treated by the advancement of a homodigital island flap. With an average follow-up of 31 months; Results were considered good or excellent in seven cases, fair in seven and poor in four. Six cases, although improved, had a marked recurrence of the deformity, six had a partial recurrence and six had almost no recurrence. Patient satisfaction was limited as the finger still had a short nail and a square shape.
