ResumoA pilot study was conducted to investigate the osteogenic potential of autogenous cancellous-marrow grafts in irradiated tissue. Three young adult mongrel dogs with large mandibles were used in this preliminary experiment. Each dog mandible received 500 rads of cobalt irradiation twice a week for 5 weeks. Discontinuity defects were created in the mandible and reconstructed immediately with a cancellous-marrow graft. Bony union occurred in all the mandibles. The quantity of new bone formed in the surgical defect varied. The graft sites showed a histologic picture generally similar to the nonsurgical side.
