Functional and aesthetic results of immediate reconstruction of traumatic thumb defects by toe-to-thumb transplantation.

Traumatic thumb defects significantly affect the function and appearance of the hand; thus, thumb reconstruction is very important in clinical practice. In our report, three reconstruction strategies of toe-to-thumb transplantation, based on the amputation level of the thumb, were used for immediate thumb reconstruction in 27 patients with traumatic thumb defects. All procedures were performed successfully. Patients were satisfied with the function and appearance of the reconstructed thumb. These results indicate that if the reconstruction method is properly selected based on the amputation level of the thumb, toe-to-thumb transplantation is feasible for the immediate reconstruction of the thumb.
