We radiologically studied fibular regeneration derived from the periosteum which had been left after removal of the fibula for bone grafting in 10 patients with bone tumors or tumourous conditions. In 7 patients all aged less than 19 years, continuous membranous ossification appeared within a few months after surgery, and then gradually thickened. Marrow cavity was observed between 3 to 17 months. Although pseudoarthrosis occurred in one case, 5 patients showed complete regeneration of the fibula. In the remaining 3 patients who were aged more than 20 years. Fibular regeneration did not occur. These results indicate that wide removal of the fibula for bone grafts should not be done after the age of 20 years because of the decrease in their ability to form bone from the periosteum.
