| Popis: | Fabrication of a new ball-shaped titanium material for vertebral compression fracture treatment has been studied using micro-arc oxidation in an electrolyte containing hydroxyapatite (HAp). To prevent microstructural disturbance on the surface, ethanol was used as a co-solvent. The material thus obtained was found to have high porosity with many micropores, fixed HAp particles on the surface, and elasticity comparable to cancellous bone. Furthermore, it was demonstrated that the materials have osteoconductivity and the elasticity was kept under cycled stress. These indicate that they can be new bone filling materials for percutaneous vertebroplasty (PV). |
