[Nail recession emergency treatment: a new technique for the repair of fingertip amputations].
BACKGROUND
In spite of the recent advances made in microsurgery, the reconstruction of oblique fingertip amputations remains problematical. In cases where reimplantation is technically impossible, the surgeon can utilize a number of different flaps to preserve digital length.


METHODS
In certain cases, instead of local flap repair using an advancement flap, the nail complex can be recessed so that after bone shortening of the distal phalanx the free edge of the nail can be stitched to the skin without resulting tension. Two longitudinal incisions are made, and a flap including the nail complex is obtained from the distal phalanx. The dissection is made as far as the base of the middle phalanx, and is superficial so that it does not affect the distal branches of the middle phalangeal arteries. This technique was used consecutively in three cases of oblique fingertip amputations.


RESULTS
The average shortening required was 10 mm. In all three cases, the nail was preserved, and pulp sensitivity was excellent (mean static two-point discrimination of 5 mm, Semmes-Weinstein monofilaments of 2.83-3.61). The mean period before return to work was 5 weeks. No proximal interphalangeal joint stiffness was noted. However, all the patients complained of pain upon exposure to cold.


CONCLUSIONS
This technique is simple to use, and combines the advantages of bone shortening with the esthetic aspect of preserving the nail complex. No palmar dissection is necessary, and the standard risks associated with advancement flap techniques are thus avoided. Although this reconstruction method results in a shorter finger, good functioning and good immediate sensitivity are maintained.
