Surgery on congenital hand anomalies can be challenging in severe malformations. Surgeons should take profit of all available anatomical parts to improve the function and aesthetics of the hand.

A careful analysis of each deformity is mandatory to choose the best parts of two digits in order to reconstruct a better finger or thumb.

Speakers will share their experiences on pedicled transfers of segments of fingers. Some examples will illustrate how we can really “push the limits”.
