There arachnodactyly rare, mainly girls. The bones of the limbs, especially the hands and feet, elongated (reminiscent of the hand and foot monkeys), sometimes narrowed; phalanxes of fingers elongated and fancifully curved resemble the legs of a spider (Fig). Often there are other malformations: exostosis heel bone, dislocation of the hip dislocation or subluxation of the lens. The growth of children for the most part below normal; chest narrowed and extended; power is reduced. Child development slowed down, sometimes there mental disabilities. Children with arachnodactyly generally unstable to infections, many of them perish in the early years of different diseases.
