Manual Of Cementing Technique

With contributions by numerous experts

G. H. I. M. WALENKAMP, D. W. MURRAY Since the first use of bone cement, there has been much discussion about this important tool in arthroplasty. Many authors consider the cemented prosthesis as the gold standard when evaluating the outcome of primary prostheses. In a large number of total hip arthroplasties, as registered in the Scandi navian Hip Registers, important differences in revision risks have been docu mented between hospitals. These differences are partly due to the use of di verse cement techniques. In the analysis of data, the influence of these tech niques, as well as the different cement types, is clear. A recent disaster with a newly developed cement also illustrated that the quality of the cement must be assured, and that the introduction of a new material must be carefully prepared and followed-up. The new Palamed cement has been developed by the makers of the well known Palacos and Refobacin Palacos, which appeared to be the best ce ments in the Swedish register. An improvement was noted in slightly better handling characteristics, but the end product is the same as Palacos. As men tioned, this cement will be carefully followed-up in the near future. However, its introduction is a good reason to gather the expertise of some of the lead ing figures in the field in this book.

The Editors of “Essentials of Cemented Knee Arthroplasty” have compiled a comprehensive textbook on what many consider the most successful surgical procedure of the century. This book rounds out the compendium previously published by Springer on arthroplasty related topics: “The Well Cemented Total Hip Arthroplasty”, “PMMA Cements”, and “Management of Periprosthetic Joint Infection”. Unique to this text is the high quality contributions from over 160 world wide experts in the field, and provides a unique international perspective on the multifaceted topic of knee replacement surgery. Sections include a focus on Surgical Indications, Implant Design, Novel Technologies, Complications, and Cementing Technique, amongst others. Each Chapter not only draws on the most current literature on the subject, but also crystalizes the most important points into clinically relevant, practically applicable “take home messages”. This singular text is notable for not only its breadth, but also its depth, and will be an invaluable resource for knee arthroplasty surgeons throughout the globe.

In bone surgery it is essential to compress fractures interfragmentarily in order to make them resistant to the tensile force of muscles and the force resulting from acceleration and deceleration. This can be best achieved by the use of cable tension bands as a traction mechanism. The cable tension band is - in terms of stability of fractures - far superior to the conventional rigid cerclage wire which has been widely used in osteosynthesis for over 100 years. The author explains the biomechanics of the tension band in detail. Theoretical findings are confirmed by clinical test results. All osteosynthetic techniques which can be carried out with cables are described giving details of operation instructions. Errors and risks are always pointed out. A reference book and operative manual at a time.

Methyl methacrylate (MMA) is the basic component of bone cements. To use it, a dough is prepared from the liquid and powder by mixing right before application, which is normally done by the operating team. During its working phase the dough is then inserted into the tissue where polymerization is completed. Thus, the final implant polymethyl methacrylate (PMMA) is only created at the implantation site. Besides methyl methacrylate, bone cements sometimes contain other methacrylates, such as butyl methacrylate. To achieve X-ray opacity, radiopacifiers (zirconium dioxide or barium sulfate) are added to the powder. Both the liquid and powder components contain additives (initiator and activator) that launch polymerization and control the set ting when mixed together. Moreover, softener and emulsifiers are some times used. The addition of antibiotics to the powder component in order to prevent or treat infections has become especially important. Commercial bone cements differ in composition and the course of curing. Some are designed for high and others for low viscosity. The way the user handles and applies the cement always crucially influences the quality of the implant. This is why clear and comprehensive information about the cements should be available to show the user how all the relevant factors work It should also be possible together and how they depend on each other.

Cemented Total Hip Arthroplasty (THA) remains one of the most successful procedures in Orthopaedic surgery. It has become very clear that it is the surgical expertise, in particular the quality of the cementing technique, which will affect long-term outcome and success. It is the intention of this book to provide an up-to-date comprehensive assessment of the entire field of cemented THA. Special emphasis has been given to practice-relevant aspects: well-illustrated and detailed operative steps as a practical guideline, a basic science chapter and long-term outcome data are provided. Minimally invasive surgery, modern perioperative management and patient fast tracking are covered. A number of highly respected experts have contributed to this in-depth compilation of the "state of the art" in 2005. This book is written and intended for both, trainees and established arthroplasty surgeons who are dedicated to perform a well-cemented THA.

The third edition of Joint Replacement Technology provides a thoroughly updated review of recent developments in joint replacement technology. Joint replacement is a standard treatment for joint degradation and has improved the quality of life of millions of patients. Collaboration between clinicians and researchers is critical to its continued success and to meet the rising expectations of patients and surgeons.This edition covers a range of updated and new content, ranging from chapters on materials analysis and selection, to methodologies and techniques used for joint replacement and clinical challenges of replacing specific joints. Key topics include tribological considerations and experiments; challenges in joint bearing surfaces; cementless fixation techniques; healing responses to implants. Clinical challenges and perspectives are covered with the aid of case studies.Thanks to its widespread collaboration and international contributors, Joint Replacement Technology, Third Edition is useful for materials scientists and engineers in both academia and the biomedical industry. Chemists, clinicians, and other researchers in this area will also find this text invaluable. This third edition provides an updated comprehensive review of recent developments in joint replacement technology Reviews a range of specific joints, biological and mechanical issues and fixation techniques Includes revised and new content, such as sections on regulatory affairs, AI techniques and 3D printing
