Radiographic Healing and Remodelling of Cortical and Cancellous Bone Grafts after Rigid Plate Fixation

Abstract
Cortical and cancellous interposition grafts, with rigid plate fixation, in the tibiofibular bones of 130 rabbits were followed radiographically for 1 yr. The cancellous grafts healed earlier, but by 12 wk both graft types were incorporated, the distal host-graft interface being the last to heal. Progressive cancellous transformation in the graft and host bone led to an increased overall bone diameter, a widened medullary canal and a thinned porotic wall.
