Osteal integration of porous implants from titanium nickelide.
The microstructure of preparations from porous titanium nickelide was studied 4.5 months and 1.5 years after operations on the anterior compartments of the spine. Organic tissues of different morphology, compactness, and thickness occupied 100% of analyzed surface 1.5 years after implantation, while after 4.5 months the pores were filled by 60%. The content of calcium and phosphorus elements in surface pores after 1.5 years was close to their concentrations in human bones.
