Bioceramics in Orthopedic Surgery

Abstract

Orthopedic surgery and traumatology is highly dependent on medical implants. Materials used in vivo must fulfill criteria as biocompatibility, ability to withstand mechanical load as well as chemical processes in organism. There is constant investigation of new materials and improving of existing ones, trying to achieve the ideal implant. Ceramics features as biocompatibility, inertness, smoothness make it very promising candidate for many orthopedic applications. At this moment majority of using of ceramics in orthopedic is for making bioactive coatings of the endoprosthesis surface achieving more rapid and stable fixation. Second is fabricating bearing surfaces from ceramics using it low friction coefficient, bioinertness and wettability properties. There are few generation of ceramics designed to improve its properties and lower the incidence of complication and failure. Majority of this occurs due to brittleness of ceramic implants. New generations show rapid decrease on incidence of complications and higher survival rates of implants. More improvements in ceramics are performed in order to lower the incidence of fracturesImplantCeramics.
