title: BIOMATERIAL IMPLANTS IN BONE FRACTURES PRODUCED IN RATS FIBULAS.
abstract: To evaluate the importance of collagen and hydroxyapatite in the regeneration of fractures experimentally induced in the fibulas of rats.
  
  
  METHODS
  15 rats were used. These were subjected to surgery to remove a fragment from the fibula. This site then received a graft consisting of a silicone tubes filled with hydroxyapatite and collagen.
  
  
  RESULTS
  Little bone neoformation occurred inside the tubes filled with the biomaterials. There was more neoformation in the tubes with collagen.
  
  
  CONCLUSIONS
  The biomaterials used demonstrated biocompatibility and osteoconductive capacity that was capable of stimulating osteogenesis, even in bones with secondary mechanical and morphological functions such as the fibula of rats.
