Objectives/Interrogation: A retrospective review was made to classify the type of nail deformity and its aesthetic evaluation in radial polydactyly which was treated by the Bilhaut-Cloquet procedure (BCP).

Methods: From January 2005 to December 2015, the BCP was performed in 129 thumbs of 125 patients with radial polydactyly. 88 thumbs of 84 patients received more than 6 months of follow-up and were included in this study. The operation age was 7 to 216 months with an average of 31.4. There were 51 males and 33 females. Uilateral radial polydactyly was in 80 patients (left: 31, right: 49), bilateral in 4. According to the Wassel classification, there were 3 cases of type I, 20 of type II, 12 of type III, 33 of type IV, 6 of type VI, and 10 of type VII. The reconstructed nail were evaluated by Wang-Gao scoring system.

Results and Conclusions: The average follow-up period was 34.4 months (6-128 months). The occurrence of different nail deformities were as follows: abnormal nail flatness were found in 51 thumbs (57.95%), lunula malposition in 27 (30.68%), malposition of the nail fold in 22 (25.0%), abnormal nail width in 16 (18.18%), dehiscence of nail or growth failure in 7 (7.95%). According to Wang-Gao score (total 12), the score was 2-12 (average 9.18). Excellent results were in 58 thumbs (65.91%), good in 23 (26.14%), fair in 5 (5.68%) and poor in 2 (2.27%).

When the BCP were used, the improvement of the thumb volume and nail width was clear. The nail deformity varied in different types and its incidence was high and. But it was mild and acceptable. Including more than 3 types of nail malformations in one thumb was the main cause of dissatisfaction among patients or family members, but the incidence was not high. Therefore, BCP is still a good choice for the patients with hypoplastic duplicated thumbs.
