Download or read book Corrosion of Modular Titanium Alloy Stems in Cementless Hip Replacement written by RM. Urban and published by . This book was released on 2005 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Severe, localized corrosion of titanium-alloy femoral stems has been reported for specific designs of hip prostheses intended for fixation using acrylic cement. The purpose of the present study was to examine the possibility that corrosion might also occur when titanium-alloy stems are inserted without cement, but the body of the stem is modular in design. Fourteen (7 primary and 7 revision) cementless, modular-body, titanium-6 % aluminum-4 % vanadium alloy femoral stems of similar design were removed at revision surgery after 2 to 108 months in situ. The reason for removal was unexplained pain (4), femoral or acetabular loosening (4), infection (3), recurrent dislocation (2), or component malposition (1). The devices and, in selected cases, tissue from the joint psuedocapsule were studied with the use of light and scanning electron microscopy. Fretting corrosion products were characterized using energy dispersive x-ray analysis, selected area diffraction, and micro-Raman spectroscopy. Damage at the modular body connections was absent in 3 stems, mild in 6, moderate in 4, and severe in 1. The surface damage was characterized predominately by fretting scars and by pitting and etching. Thick deposits of mixed titanium oxides were found adherent to the stem at the sites of corrosion and as 0.01 to 200 micrometer particles within histiocytes and multinucleated giant cells in the joint pseudocapsule. Fretting corrosion at the modular-body junctions of titanium-alloy femoral stems can generate solid degradation products, adding to the particulate biu-den of the periprosthetic tissues and potentially accelerating bearing-surface wear by a third-body mechanism. Both of these features can potentiate the development and progression of osteolysis. In addition, fretting corrosion can increase the potential for structural failure of the device. These findings stress the importance of the design of modular junctions to minimize corrosion and the generation of corrosion products.

Download or read book Personalized Hip and Knee Joint Replacement written by Charles Rivière and published by Springer Nature. This book was released on 2020-06-30 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book describes and illustrates the surgical techniques, implants, and technologies used for the purpose of personalized implantation of hip and knee components. This new and flourishing treatment philosophy offers important benefits over conventional systematic techniques, including component positioning appropriate to individual anatomy, improved surgical reproducibility and prosthetic performance, and a reduction in complications. The techniques described in the book aim to reproduce patients’ native anatomy and physiological joint laxity, thereby improving the prosthetic hip/knee kinematics and functional outcomes in the quest of the forgotten joint. They include kinematically aligned total knee/total hip arthroplasty, partial knee replacement, and hip resurfacing. The relevance of available and emerging technological tools for these personalized approaches is also explained, with coverage of, for example, robotics, computer-assisted surgery, and augmented reality. Contributions from surgeons who are considered world leaders in diverse fields of this novel surgical philosophy make this open access book will invaluable to a wide readership, from trainees at all levels to consultants practicing lower limb surgery

Available in PDF, EPUB and Kindle. Book excerpt: The Corail® Hip System was developed in 1986 as an innovative solution for hip arthroplasty and has since become one of the most used hip systems in the world. This book is designed as a practical manual to primary and revision arthroplasty that will serve both as a reference for surgeons in training and as a source of information, tips and tricks for the more experienced who wish to learn from the cases of other surgeons. The book is divided into three main parts. The first discusses everything that is practical about the system, including the surgical technique, treatment of complications, and the results achieved in large cohorts of patients. The second part is devoted to the important issues of surgical approach, bearing options, acetabular preparation and, cup orientation and fixation. The final part focuses on patient management and includes a collection of standard and complex clinical cases to which surgeons can refer when planning surgery.
Download or read book Arthroplasty 2000 written by N. Matsui and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Joint replacement surgery has seen remarkable progress and development in recent years both in prostheses and in surgical technique. A prime concern has been improved durability, for which a major factor is reduction of the polyethylene wear that leads to osteolysis. This book presents an update on the means by which the problems of wear and loosening are being addressed in total hip arthroplasty (THA) and total knee arthroplasty (TKA). Included are chapters on new surgical techniques for difficult cases, nonpolyethylene interfaces for THA, custom hip prostheses, and computer-assisted surgery. Arthroplasty 2000 also takes up current controversial issues such as posterior cruciate substitution versus retention in TKA. With contributions by eminent specialists in total joint replacement in Asia, Europe, and North America, this volume is a valuable reference for all orthopedic surgeons.

Download or read book Particulate Associated Endosteal Osteolysis in Titanium Base Alloy Cementless Total Hip Replacement written by JO. Galante and published by . This book was released on 1992 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fourteen cases of diaphyseal endosteal erosions adjacent to the femoral stem have been identified in our patient population of 308 primary cementless titanium alloy total hip replacements at minimum two-year follow-up. Three of these cases were associated with unstable prostheses that resulted in revision surgery. Eleven cases were associated with radiographically stable prostheses. one of which was revised. Capsular tissue and interfacial membrane tissue were harvested from the four cases that were revised. All the tissues were analyzed histologically. and selected tissues were analyzed with electron microprobe analysis (EMA). analytic electron microscopy (AEM). and Fourier transform infrared spectroscopy (FTIR). Standard hematoxylin and eosin sections demonstrated histiocytic infiltration of the capsular and interfacial membrane tissue. These cells were laden with fine intracellular birefringent material. EMA revealed the presence of titanium alloy particles and AEM documented titanium alloy particles as well as silicate particles. FTIR positively identified polyethylene-like particles, but this technique was not able to identify particles less than 10 ?m in diameter. Femoral endosteal osteolysis appears to be mediated by histiocytes containing both metallic and polymeric wear debris.
