The treatment of crossbones of the hand

Over a thirty-year period at Loma Linda University, we have seen eight patients with nine crossbones of the hand. These patients fall into the group of central deficiency with a cleft hand and central polydactyly. As will be noted in the paper, these two conditions may have a similar developmental relationship. Although the literature in the past specifies mainly one option - to remove the crossbone - we consider several different options that one should think about before removal of the crossbones.
