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

Book Synopsis Aseptic Loosening of Orthopedic Implants by : Mehdi Amirhosseini
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.

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.

Book Synopsis The Hip Bone's Connected to the Orthopaedic Implant by : Jordan Raphel
Download or read book The Hip Bone's Connected to the Orthopaedic Implant written by Jordan Raphel and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A vast array of implants are employed clinically to interface directly with living bone. These implants include orthopaedic prostheses, such as artificial hip and knee replacements, orthopaedic bone screws, and dental implants and are commonly made from titanium and its alloys. Over one million joint replacements and screws are implanted each year in the United States. In order for these implants to function successfully, they require strong osseointegration, the stable and functional connection between the implant and bone. Unfortunately, approximately 10% of implants fail prematurely, and many of these failures are due to poor osseointegration leading to implant loosening. Failures also occur due to microbial infection, which can be severely debilitating to the patient and may necessitate the removal of the implant. Approximately 1-3% of implants become infected, creating a large burden for the patients and the healthcare system. In this work, a versatile coating technology for bone-interfacing implants is developed to improve implant osseointegration and to provide defense from microbial infection. The coatings are derived from an engineered, elastin-like protein (ELP) that is recombinantly expressed in Escherichia coli. The ELP contains functional domains from two natural extracellular matrix proteins - elastin and fibronectin - to confer specific mechanical and biochemical properties, respectively. The elastin-like domain provides mechanical toughness and resiliency, while the fibronectin-derived RGD domain is cell-adhesive. Thin-film coatings made from ELP can be processed by a variety of methods to coat implants of any shape or size. To stabilize the coatings and adhere them to implant surfaces, a novel covalent crosslinking strategy is employed. Lysine residues are strategically substituted into the elastin-like domains to provide sites for chemical modification of the ELP through the primary amines present on the lysine side chains. A photoactive heterobifunctional crosslinker, NHS-diazirine, is conjugated through these primary amines, rendering the ELP photocrosslinkable upon exposure to ultraviolet (UV) light. The activated diazirine moiety interposes into neighboring bonds, leading to a covalently crosslinked ELP hydrogel. Furthermore, the diazirine can also covalently conjugate to common implant materials through the same UV-mediated mechanism, thereby creating a stable ELP thin-film coating with strong adhesion to implants. Good osseointegration of implants reduces the chance of aseptic loosening while poor osseointegration allows for micromotion of the implant relative to the bone, causing wear, inflammation, and implant loosening. By encouraging new bone deposition on the implant surface, osseointegration can be improved by stabilizing the bone-implant interface. The ELP coatings are able to enhance osseointegration by interacting with native osteogenic cells, including osteoblasts and mesenchymal stem cells (MSCs) through the RGD ligand. The presence of the ligand facilitates rapid cell adhesion, and the ELP coatings demonstrate the ability to improve osteogenic differentiation and bone mineral deposition in vitro, key steps for new bone formation and improved osseointegration. The coatings also improve osseointegration markers in vivo. Microbial infection is another leading cause of implant failure. Bacteria readily adhere to implant surfaces and form biofilms resistant to systemic antibiotic treatments, necessitating alternative strategies to prevent and treat implant-site infections. The antimicrobial properties of silver have long been known, and here it is employed as a localized defense against infection by incorporating silver chloride nanoparticles into the ELP coatings. These antimicrobial coatings rapidly kill over 95% of Staphylococcus aureus, the most common implant pathogen. The achievements presented in this work demonstrate significant advancements for implant coating technologies and have strong potential for clinical translation to improve implant function, lifetime, and efficacy.
