The long-term fate of implants of anorganic bone, prepared by removal of organic fractions of heterogeneous bone, was studied histologically in dogs. After implantation in an orthotropic site the marrow-vascular spaces of anorganic bone were invaded by host osteogenic tissue. Subsequently, the anorganic material occupied space and was not remodeled significantiy during a one-year observation period. Cathode-irradiated, frozen homograft controls were replaced by host bone with the passage of time. The clinical use of anorganic bone does not seem indicated from these studies. (C.H.) |
