Abstract

To assess the role of collagen and hydroxyapatite in the healing of experimentally generated fractures in rat fibulas. 15 rats were utilised as the method. Surgery was performed on these to reposition a fragment from the fibula. A silicone tube graft containing hydroxyapatite and collagen was then applied to this location. Results: Almost no new bone growth Third-year medical student at Brazil's Judie School of Medicine. A fourth-year medical student at Brazil's india School of Medicine. PhD. Adjunct Professor at the Judie School of Medicine in Jundia, SP, Brazil in the Department of Morphology and Basic Pathology, Discipline of Anatomy. Work created in the Morphology and Basic Pathology Department at the undia School of Medicine in Jundia. Occurred inside the biomaterial-filled tubes. In the tubes containing colla- gen, there was greater neoformation. Conclusion: Even in bones with secondary mechanical and morphological functions, like the rat fibula, the biomaterials used demonstrated biocompatibility and osteoconductive capacity that was able to stimulate ontogenesis.
