(Feb 9th) In this video lecture, Prof. Lisa Pruitt lectures on Wear in Total Joint Replacements.
Topics in this lecture:
Litigation issues, material development, gamma radiation sterilization, Poly II (carbon fiber reinforcement), bulk crosslinking, effects of radiation on the structural and mechanical properties, WEAR in TJR, Mechanisms of Wear, RMS roughness, wear debris, fatigue wear, wear damage, wear-mediated osteolysis, Archard's law
This course of UC Berkeley - Bio Engineering/ME C117: Structural Aspects of Biomaterials - provides an overview of medical devices, FDA regulatory issues, biocompatibility and sterilization technology. It examines biomechanical properties: isotropy/anisotropy, stiffness, bending stresses, contact stresses, multiaxial loading, plasticity, fatigue, fracture, wear, corrosion, design issues. Also covered: Orthopedics, Dental, Cardiovascular, and Soft Tissue Reconstruction.Professor Pruitt's current research is focused on fatigue and fracture micromechanisms, cyclic damage zones, and evolution of structure due to cyclic loading and environment in advanced polymers and biomaterials.
