Metal-on-Metal Bearings: A Clinical Practicum Lynne C Jones 2014 edition

Marc Notes: This text addresses the background and significance of factors potentially influencing clinical and biological outcomes of metal-on-metal hip implants. It includes discussion of reported complications including pseudotumors and other lymphocytic-based responses.

Metal-on-metal bearings were introduced and evaluated as an alternative to other bearing couples, particularly metal-on-polyethylene, due to their enhanced wear resistance as determined in laboratory testing. Initially, reports of short-term clinical outcomes were favorable and an increasing number of metal-on-metal prostheses were implanted. Subsequently, isolated case findings describing adverse tissue responses around the articulation became the harbinger of an increasing number of reports describing pseudotumors and other significant lymphocytic-based responses associated with metal-on-metal prostheses. Questions have been raised as to whether this is an implant, design, or patient-specific response. The reasons why some patients have a negative biological response and pathology while others do not remain to be determined, but tens of thousands of patients in the US, the UK, and around the world are considered to be at risk. Leading researchers and clinicians describe the issues related to the nature of the biological and pathological responses and the protocols that should be followed to determine if an adverse response is occurring. This book is essential reading for researchers, engineers, and orthopaedic surgeons who are involved in the design, evaluation, and implantation of metal-on-metal prostheses. Presents an historical overview of the use of metal-on-metal articulationsCollects for the first time the information necessary to assess clinically and biologically relevant patient outcomes Addresses the practical questions that are being raised by surgeons, researchers, and engineers Features contributions by acknowledged leaders in their fieldsDescribes what the clinician needs to know in order to practice evidence-based medicineProjects directions for clinical, biological, and biomechanical research efforts"Publisher Marketing: This book addresses the background and significance of the factors potentially influencing the clinical and biological outcomes of metal-on-metal hip implants.
