Abstract
Methods for performing a hemiarthroplasty procedure. In some implementations, the method may comprise providing a component of an endoprosthesis, such as a femoral component of a hip prosthesis. The component may comprise a silicon nitride ceramic material, and may further comprise a coated articulating surface. The coated articulating surface may comprise a coating configured to reduce a coefficient of friction of the articulating surface. The method may further comprise positioning the endoprosthesis such that the coated articulating surface is positioned adjacent to a patient's native articular cartilage. In this manner, the coated articulating surface may articulate with the native articular cartilage following the procedure.
Claims20
A method for performing a hemiarthroplasty procedure, the method comprising the steps of:
- providing a component of an endoprosthesis, wherein the component comprises a silicon nitride ceramic material, and wherein the component further comprises a coated articulating surface comprising a coating, wherein the coating comprises at least one of diamond-like carbon, silicon carbide, titanium nitride, titanium diboride, titanium carbonitride, titanium aluminum nitride, chromium nitride, chromium carbonitride, and titanium silicon carbonitride;
- and
- positioning the endoprosthesis such that the coated articulating surface is positioned adjacent to a patient's native articular cartilage such that the coated articulating surface is configured to articulate with the native articular cartilage following the procedure.
A method for applying a coating to an articulating surface of an endoprosthesis, the method comprising the steps of:
- providing a component of an endoprosthesis, wherein the component comprises an articulating surface, wherein the articulating surface is configured to interface with a patient's native articular cartilage, and wherein the component comprises a silicon nitride ceramic material;
- applying a coating to the articulating surface, wherein the coating comprises at least one of diamond-like carbon, silicon carbide, titanium nitride, titanium diboride, titanium carbonitride, titanium aluminum nitride, chromium nitride, chromium carbonitride, and titanium silicon carbonitride.
A method for performing a hip hemiarthroplasty procedure, the method comprising the steps of:
- providing a femoral component comprising a femoral head and a stem, wherein the stem is configured to be coupled with an upper end of a patient's femur, wherein the femoral component comprises a doped silicon nitride ceramic material comprising dopants selected from the group consisting of yttrium oxide, magnesium oxide, strontium oxide, aluminum oxide, and combinations thereof, wherein the femoral head comprises a coated articulating surface comprising a coating, wherein the coating comprises at least one of diamond-like carbon, silicon carbide, titanium nitride, titanium diboride, titanium carbonitride, titanium aluminum nitride, chromium nitride, chromium carbonitride, and titanium silicon carbonitride, wherein the coated articulating surface has a coefficient of friction of no more than about 0.01, and wherein the femoral component other than the coated articulating surface has a coefficient of friction of at least about 0.1;
- and
- positioning the femoral component such that the coated articulating surface is positioned adjacent to a patient's native articular cartilage within the patient's acetabulum such that the coated articulating surface is configured to articulate with the native articular cartilage following the procedure.
