This book was released on 2013-11-19 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Total joint arthroplasty is an effective surgical procedure for end-stage osteoarthritis of major joints with satisfactory long term clinical outcome. A large and growing number of arthroplasties are performed annually worldwide and a great number of orthopaedic surgeons are practicing arthroplasty surgery as their main surgical activity. The biological behavior of the bone-implant interface is crucial for the long term survival of the artificial joint. All factors which have a positive or negative effect on the interface are of great interest for those practicing arthroplasty surgery. Basic scientists and the industry are continuously searching for new implant fixation mechanisms and improved materials. There is an accumulation of a great amount of basic science data (both biological, material and mechanical) related to the incorporation or loosening of the bone-implant interface. However, basic science data does not always translate to satisfactory clinical application, and orthopaedic practitioners often wonder which piece of information is clinically useful. A further problem is that basic scientists often speak their own scientific language and may not fully appreciate common clinical practice needs. In this textbook the biological and mechanical mechanisms of implant incorporation and loosening will be presented. All new data concerning materials and methods for incorporation enhancement will be critically analyzed. Data useful for clinical application will be stressed. Orthopaedic Surgeons will find information which will improve their clinical practice and basic scientists will be helped to understand and appreciate clinical needs.

Download or read book Interactions of Bone with Orthopedic Implants and Possible Failures written by Amirhossein Goharian and published by Academic Press. This book was released on 2022-07-20 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interactions of Bone with Orthopedic Implants and Possible Failures focuses on the mechanical and biological issues that may cause failure of the implant-bone construct. The book provides discussions on the effects of the design, process, surface and other engineering parameters of implants and their interaction with bone tissue. For implant designers, it is highly crucial to know the final effects of what they are designing or aiming to design, along with performance parameters. It is also crucial for orthopedic surgeons to be familiar with the background of the design and process parameters of the implant they will insert in a patient’s body. With the understanding brought forth in this book, surgeons can have better implant options and implant designers can create and develop new implant designs. This book can also help biomechanical and mechanical engineers who are normally dealing with testing and analysis of orthopedic implants examine the biomechanical behavior of the implants and their interaction with bone tissue. Explains interactions, along with possible complications of trauma, joint and spinal implants, and failures of the implant and bone tissue Focuses on issues such as bone loss, defects and resorption at the bone and implant interface Includes case studies of implant failures and discusses the mechanical and biological reasons that would cause failure of bone and implant integration

Download or read book Materials Sciences and Implant Orthopedic Surgery written by R. Kossowsky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combining experts from the medical and materials sciences, the Institute considered current concepts in medical and materials sciences as they relate to implantable prostheses in orthopedic surgical practice. The syllabus included theory and applications of materials properties, physiological function, and host response to metal and non-metal materials. Total hip prostheses are the most common orthopedic device implanted today involved in over 200,000 operations. Failures occur at the rate of 10~-40~ at ~ to 10 years. Failures are due to loosening, infection, fracture of femoral components, or destruction of the pe 1 vi c components .' All these, and other problems related to the implantation of the devices, the surgical procedures, and device pathology, were. discussed in light of current, as well as, emerging technologies and scientific knowledge. Repeatedly, scientists designing prostheses became aware of a lack of understanding of physiological phenomena associated with biocompatibility; the interchange among practising physicians, basic scientists, and pathologists at this Institute was appreciated. We thank all the contributors and participants for their effort. Thanks are also due to the personnel of the Scientific Affairs Division of NATO. The daily routines of running the Institute were greatly facilitated by the efforts of Pedro Cuevas, M.D, Jose Gutierrez Diaz, M.D, and Dr. Hanita Kossowsky. The devoted help of Nir Kossovsky, M.D, in setting the conference and in editing this book, is sincerely appreci ated.

Download or read book A Modern Approach to Biofilm Related Orthopaedic Implant Infections written by Lorenzo Drago and published by Springer. This book was released on 2017-05-16 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses Prosthetic Joint Infection (PJI), which remains one of the most common problems necessitating revision arthroplasty. It pursues a multidisciplinary approach, bringing together opinions from the leading experts in the field. The book identifies the potential causes of these infections, provides sound diagnostic criteria guidelines, and explains how these prosthetic infections are managed from orthopedic surgery, clinical and diagnostic perspectives. PJI can lead to multiple revision surgeries and significant patient morbidity. Periprosthetic infection rates remain around 1–2% after primary total hip and knee arthroplasty and account for approximately 7–12% of all revision cases. Orthopedic hardware infections are much-feared and costly complications that can occur when these devices are implemented both in traumatic cases as well as in joint replacement surgery. Because these infections can lead to higher morbidity, it is important to understand their pathophysiology and the principles behind their diagnosis and initial treatment. The pathogenesis of these kinds of infections is intimately connected to the biofilm-producing trait characteristic of many microorganisms, which can have a critical effect on the likely success of treatments. The book offers a unique guide for all scientists working in arthroplasty who are seeking an update on the field, and for newcomers alike.

In addition, it is analyzed how surface alterations have changed the clinical long-term results for certain groups of patients.

Download or read book Aseptic Loosening of Orthopedic Implants written by Mehdi Amirhosseini and published by Linköping University Electronic Press. This book was released on 2019-05-24 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aseptic loosening is the main cause of failure of orthopedic prostheses. With no pharmaceuticals to prevent or mitigate periprosthetic bone degradation, a surgery to replace the loose implant with a new one is the only choice to restore patients’ function. Most studies on mechanisms for aseptic loosening investigate wear debris particle-induced osteolysis. However, pathological loading conditions around unstable implants can also trigger osteoclast differentiation and bone loss. In the first study, global gene expression changes induced by mechanical instability of implants, and by titanium particles were compared in a validated rat model for aseptic loosening. Microarray analysis showed that similar signaling pathways and gene expression patterns are involved in particle- and instability-induced periprosthetic osteolysis with an early onset innate immune response as a hallmark of osteolysis induced by mechanical instability. Further, effects of potential therapeutics on restriction of excessive osteoclast differentiation were evaluated. Wnt signaling pathway is known to regulate bone remodeling. In the second study, effects of inactivation of glycogen synthase kinase 3 beta (GSK-3?), a negative regulator of canonical Wnt signaling, on instability-induced periprosthetic osteolysis were examined using our rat model for aseptic loosening. Inhibition of GSK-3? led to a decrease in osteoclast numbers in the periprosthetic bone tissue exposed to mechanical instability while osteoblast perimeter showed an increase. This was accompanied by higher bone volume fraction (BV/TV) in animals treated with the GSK-3? inhibitor. In the third study, potential beneficial effects of two selective inhibitors of cyclindependent kinase 8/19 (CDK8/19) on bone tissue were evaluated. CDK8/19 is a Mediator complex-associated transcriptional regulator involved in several signaling pathways. CDK8/19 inhibitors, mainly under investigation as treatments for tumors, are reported to enhance osteoblast differentiation and bone formation. We show in this study, for the first time, that inhibition of CDK8/19 led to marked suppression of osteoclast differentiation from bone marrow macrophages in vitro through disruption of the RANK signaling. In mouse primary osteoblasts downregulation of osteopontin mRNA, a negative regulator of mineralization, together with increased alkaline phosphatase activity and calcium deposition indicated that osteoblast mineralization was promoted by CDK8/19 inhibition. Moreover, local administration of a CDK8/19 inhibitor promoted cancellous bone regeneration in a rat model for bone healing. These studies contribute to better understanding of mechanisms behind mechanical instability-induced periprosthetic osteolysis and propose potential therapeutics to restrict bone loss with effects on both osteoclasts and osteoblasts.
