Healing of canine autogenous cancellous bone graft donor sites.

Autogenous cancellous bone was procured from the proximal ends of one humerus and the contralateral tibia of eight adult mixed-breed dogs. Greater weights of bone were consistently harvested from the humerus than from the tibia. Restoration of cancellous bone was more rapid and complete in the humerus than in the tibia. The tibia harvest site filled primarily with fibrous tissue rather than with cancellous bone.
