RISLubrication Model of an Artificial Hip Joint: Pressure Profile Versus Inclination Angle of the Acetabular Cup
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Formulation of a three-dimensional, quasi-static lubrication model of an artificial hip joint is proposed which includes the inclination angle of the acetabular cup. This is performed by deriving ...
Bio-Ferrography to Capture and Separate Polyethylene Wear Debris from Hip Simulator Fluid and Compared with Conventional Filter Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes an experimental method, bio-ferrography, to separate ultrahigh molecular weight polyethylene (UHMWPE) wear debris, generated in hip simulators, from bovine serum lubricating ...
3-D Model of a Total Hip Replacement In Vivo Providing Hydrodynamic Pressure and Film Thickness for Walking and Bicycling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Formulation of a 3-D lubrication simulation of a total hip replacement in vivo is presented using a finite difference approach. The goal is to determine if hydrodynamic lubrication is taking ...
MRI Guided 3D Mesh Generation and Registration for Biological Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An accurate three-dimensional (3D) mesh of biological models is fundamental for analysis and treatment simulations. Generally noninvasive magnetic resonance image (MRI) data are taken as the input ...
