On-Top-Plasty for Atypical Thumb Duplication: A Case Report With 10 Year Follow-up.

ABSTRACT:

Background

A very uncommon pattern of thumb duplication consists of an ulnar-side floating thumb and a radial-side distally hypoplastic thumb.

Methods

We report the case of a 15-month-old child with this type of thumb duplication on his right hand treated with an on-top-plasty technique. The ulnar-side segment was pedicled and transferred to the lateral thumb, which was distally resected.

Results

A well-aligned and widely mobile thumb with a wide first web and an excellent cosmetic appearance was exhibited 10 years after surgery.

Conclusions

On-top-plasty technique might be amenable to reconstruct certain atypical thumb duplications.
