DOWNLOAD EBOOK →UHMWPE Biomaterials Handbook describes the science, development, properties and application of of ultra-high molecular weight polyethylene (UHMWPE) used in artificial joints. This material is currently used in 1.4 million patients around the world every year for use in the hip, knee, upper extremities, and spine. Since the publication of the 1st edition there have been major advances in the development and clinical adoption of highly crosslinked UHMWPE for hip and knee replacement. There has also been a major international effort to introduce Vitamin E stabilized UHMWPE for patients. The accumulated knowledge on these two classes of materials are a key feature of the 2nd edition, along with an additional 19 additional chapters providing coverage of the key engineering aspects (biomechanical and materials science) and clinical/biological performance of UHMWPE, providing a more complete reference for industrial and academic materials specialists, and for surgeons and clinicians who require an understanding of the biomaterials properties of UHMWPE to work successfully on patient applications. The UHMWPE Handbook is the comprehensive reference for professionals, researchers, and clinicians working with biomaterials technologies for joint replacement New to this edition: 19 new chapters keep readers up to date with this fast moving topic, including a new section on UHMWPE biomaterials; highly crosslinked UHMWPE for hip and knee replacement; Vitamin E stabilized UHMWPE for patients; clinical performance, tribology an biologic interaction of UHMWPE State-of-the-art coverage of UHMWPE technology, orthopedic applications, biomaterial characterisation and engineering aspects from recognised leaders in the field

DOWNLOAD EBOOK →Recently, the orthopedic industry developed new processing techniques (radiation crosslinking), which are expected to dramatically reduce wear and improve the longevity of hip implants beyond 10 years. This book describes the history and properties of ultra-high molecular weight polyethylene (UHMWPE) used in artificial joints by describing its properties and reviewing the latest clinical results. * The most up-to-date information on the properties of UHMWPE * Endorsed by Ticona - the world's leading manufacturer of UHMWPE for medical use * An enormous 'installed base' of over 1.4 million procedures each year * UHMWPE has been used by orthopedists for over 40 years, yet its properties and performance in situ are still not well understood

DOWNLOAD EBOOK →The aim of this work was the characterization of the surface modified Ultra High Molecular Weight Polyethylene (UHMWPE) in order to understand the effect of ion implantation technique on the properties of this material. The samples were Ag and Ag+N hybrid ion implanted by using MEVVA (Metal Vapour Vacuum Arc) ion implantation technique with a fluence of 10 17 ions/cm2, extraction voltage of 30 kV.Untreated and surface treated samples were investigated by Stopping andRange of Ions into Matters (SRIM), Rutherford Back Scattered Analysis (RBS), Attenuated Total Reflection - Fourier Transform Infrared (ATR/FT-IR) Spectroscopy, Raman Spectroscopy, Optical Absorption Photospectroscopy (OAP), Thermo Gravimetry Analysis (TGA), Differential Scanning Calorimetry (DSC), X-Ray Diffraction (XRD) Analysis, Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM), Optical Microscopy (OM), Micro-hardness and Contact Angle Measurement. The results of RBS analysis show that Ag ions were detected up to 32 +15 nm after Ag implantation, and 42 +15 nm after Ag+N implantation., underneath the surface. ATR- FTIR chemical characterization analyses results indicated that the effect of implantation on UHMWPE surfaces caused dehydrogenation of polymer with an increase of C=C bond formation which results in enriching the crosslinking carbon atoms on the surface. Optical Absorption Photospectroscopy and Raman spectrum suggests that the chemical structure of UHMWPE has changed after implantation. The characterization results showed that the ion bombardment induced an increase in the % crystallinity, onset and termination degradation temperatures of UHMWPE obtained by thermal analyses, an increase in hardness, and surface wettability and a decrease in roughness of the polymer. The surface topography results can be attributed to the implantation inducing surface roughness decreasing due to the better wettability properties of surfaces obtained after implantation. In conclusion, this study has shown that ion implantation represents a powerful tool on modifying key properties on UHMWPE surfaces.

DOWNLOAD EBOOK →This book aims to give readers a basic understanding of commonly used additive manufacturing techniques as well as the tools to fully utilise the strengths of additive manufacturing through the modelling and design phase all the way through to post processing. Guidelines for 3D-printed biomedical implants are also provided. Current biomedical applications of 3D printing are discussed, including indirect applications in the rapid manufacture of prototype tooling and direct applications in the orthopaedics, cardiovascular, drug delivery, ear-nose-throat, and tissue engineering fields. Polymer-Based Additive Manufacturing: Biomedical Applications is an ideal resource for students, researchers, and those working in industry seeking to better understand the medical applications of additive manufacturing.
