Clinical Effects of Distal Phalanges and Nail Bed Fusion in Type III Thumb Duplication.

ABSTRACT:

Background

This study aimed to investigate the clinical effects of bone fusion distal to the phalangeal epiphyseal plate in treating asymmetrical type III thumb polydactyly, focusing on growth and scar healing.

Methods

In patients with asymmetrical type III thumb syndactyly, the proximal phalanx of the accessory finger, distal epiphyseal plate, and some soft tissue were excised to create a pedicled tissue flap. This flap, containing part of the nail and bone distal to the epiphyseal plate, was subsequently attached to the distal segment of the main finger. The therapeutic effect was evaluated during follow-up.
