TRANSPLANTATION OF EPIPHYSIAL CARTILAGE

Abstract

1. An experimental technique for the transplantation of epiphysial cartilage in the rabbit is described. 2. Autogenous transposition of the distal epiphysial cartilage of the ulna was followed by normal growth in five of eighteen animals. 3. Homogenous transplantation was unsuccessful in all the animals studied. 4. Homogenous grafting gives rise to an immunity reaction confined to the reserve Zone of the cartilage. 5. It is suggested that the difference between the fate of homogenous grafts of epiphysial and non-epiphysial cartilage lies in the vascularity of the former.
