[Reconstruction of distal loss of substance in the nail-bed by a de-epithelialized flap from the digital pulp].

Twelve patients, presenting with traumatic avulsion of the distal nail bed, repaired by a de-epithelialized palmar advancement flap, were reviewed with an average follow-up of 23 months. Subjective results were considered excellent in two cases, good in seven, fair in two and poor in one patient. Nail adherence with the de-epithelialized flap was observed over almost 90% of the new nail bed. Nail dystrophy was observed in three patients, but was severe in only one. Two patients had slight curvature of their nail, while one had a severe hook-nail deformity. Mobility in the finger was always complete, and only one patient had a slightly decreased two-point discrimination on the flap.
