Abstract:
Objective:In this study, a new surgical technique was developed to reconstruct the lateral nail fold in the duplicated thumbs with a common nail and postoperative outcomes were evaluated.
Methods:From December 2012 to October 2015, sixteen duplicated thumbs with a common nail were treated in our hospital using a flap from resected finger pulp which did not include the nail and phalanx. Unilateral inverting suture was performed between the flap and nail bed to reconstruct the lateral nail fold and nail groove. Postoperative outcomes were evaluated by Wang-Gao scoring system (total 12).
Results:The follow-up period ranged from 10 to 45 months. The reconstructed nails were smooth and had a natural lunula, and the nail width was about 80%-100% of their normal sides. There was a right angle between the nail epithelium and lateral nail fold in four cases, and an acute angle in two cases. The reconstructed nails were asymmetrical in these thumbs. One patient showed a hypertrophy in the lateral nail fold. The reconstructed nails were evaluated by Wang-Gao scoring system: 10 in 2 cases, 11 in 4 and 12 in 10. All the cases had excellent results.
Conclusions:The nail width usually is more than 80% of the normal sides in the radial polydactyly with a common nail. The surgical technique can reconstruct a natural lateral nail fold and nail groove, and avoid the nail deformity caused by the Bilhaut-Cloquet procedure.
