[Reconstruction and Replacement of the grip function in the maimed hand (author's transl)]

The minimum requirement for a functional hand is the presence of one or more fingers to which a sensitive, mobile thumb separated from them by a deep cleft can be opposed. Of the reconstructive techniques available for the hand, those for the thumb are the most numerous, and they are usually applied at a secondary operation. Reconstruction can only be performed at primary surgery if the state of the hand and the resources available in terms of surgical facilities and personnel are ideal, which is of the bony structure as possible, to be used as a base for reconstruction later.
