This is an experimental study on the potential of revascularized periosteal allografts for repair of bony defects. Beijing long‐eared white rabbits were used as donors and immunologically incompatible Chinchilla rabbits were used as recipients. The periosteum was stripped off from the femurs of the 6 donor rabbits and transplanted to bony defects of 1.2 cm over the radius of the 12 recipients using microsurgical anastomoses of the blood vessels. In the control group of 8 rabbits the same radial bony defects were produced without the transplantation of periosteal grafts. Immunosuppressants were administered after surgery. The animals were observed for 4 months using a series of radiography, histomorphology, fluochrome labelling and electron microscopy. Results revealed no bony healing of the defects in the control group, but 9 of the 12 defects healed in the experimental group. The results indicated revascularized periosteal allografts were able to form new bone and heal the 1.2 cm radial bone defect in rabbits. © 1994 Wiley‐Liss, Inc.
