Book excerpt: Excerpt from A New Method of Direct Fixation of the Fragments in Compound and Ununited Fractures Riedinger1 made experiments on animals in reference to the fate of ivory nails and fragments Of bone and other material implanted into living bone. Wood, rubber, etc., produced in every instance suppuration, and was invariably eliminated. Ivory and fragments of bone, even if taken from another species of animals, produced no such result, and were gradually reduced in size, and finally disappeared. He made the observation that the speed with which the material disappeared by absorption depended on the vascularity of the bone. In one experiment a fragment of bone which was driven into a perforation Of the shaft of a long bone did not undergo absorption except that part which projected into the medullary cavity. He ascertained, also, by his experiments that ivory or bone pegs driven into the shaft of a long bone brought about elongation of the bone. Two ivory pegs inserted into the left tibia of a dog increased the length of the bone 4 mm. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
