Abstract
Purpose
To evaluate nail appearance after nail fusion plasty to treat thumb duplication.
Methods
A modified form of nail fusion plasty was performed on 17 reconstructed thumbs of
16 children with thumb duplications, commencing in January 2010. We assessed nail
width and nail, lunular, and nail fold deformities using the Wang-Gao scoring system.
All 17 thumbs were evaluated over an average of 32 months (range, 12–48 months) of
follow-up.
Results
One patient with bilateral thumb deformities was excluded. The width ratios of 15
reconstructed nails (compared with those of the contralateral thumbs) were 82–118%
(average, 97%). Nine thumbs exhibited nail ridges or gaps; the average ridge/gap score
was 1.23 (maximum, 2). Six thumbs exhibited lunular deformities; the average score
was 1.58 (maximum, 2). Another six thumbs evidenced nail fold deformities; the average
score was 1.64 (maximum, 2). Only one thumb exhibited nail dehiscence. Two thumbs
had no nail deformity. The final assessments were excellent in 14 cases, good in 2
cases, and fair in 1 case.
Conclusions
We could not significantly reduce the deformity rate of the nail plate, nail fold,
or lunula using our new technique, but the deformities were much less marked than
previously. Nail fusion plasty usefully enlarges the nail and pulp in patients with
hypoplastically duplicated thumbs.
