Ten callus distraction-lengthening procedures were performed in 10 distal phalanges to correct contracted nail deformities. The average age of the patients was 28.8 (14∼41) years. A 1-week resting period was allowed, followed by gradual lengthening at a rate of 0.125 mm/day. The average lengthening achieved was 9.8 mm (86.3%; 43%∼218%). The healing indices were 68.6 days/cm. Additional minor procedures for the paronychium, nail bed, and hyponichium were performed in 6 cases. All patients were satisfied with the reformed nail, which overcame the disfigurements resulting from a deficiency of the bone and soft tissue. Distraction lengthening along with the microvascular free toenail transfer is recommended for nail reconstructions due to its simultaneous gain of bone and soft tissue.
