      The repair process using Phemister-Charnley bone-grafting in 3-week-old radial fractures of dogs and the contribution of the graft to the process have been experimentally studied. The dogs were sacrificed from 3 days to 12 weeks after bone-grafting; the results were evaluated histologically, histochemically, by the oxytetracycline (OTC) fluorescence method, and by microradiography. Marginally the graft was invaded at an early stage by granulation tissue and new bone, mainly from the periosteum. The trabeculae of the cancellous bone-graft preserved their osteocyte nuclei in places for 4 weeks, although areas without nuclei were found. Six weeks after grafting, bony union between the fragments was verified by all methods. Remodelling occurred in accordance with the functional demand. In this study Phemister-Charnley bone-grafting seemed to activate repair, particularly in the early stage.
