We report a set of 16 children carriers of 23 central aplasia of the hand, it was about 14 hands in lobster pincer and 9 hands in folk. In any case, the gene was merely aesthetic, the hand's function was complete. A child has been operated, and benefitted a closing of the median crack defect, he had a free thumb. For the other cases, abstention has been decided indeed to close this cracks deprive these hands of a first corner the alone present
