The Cementless Fixation Of Hip Endoprostheses

The main problem with regard to alloplastic joints is the loosening of the implant. Twenty years ago, Charnley first introduced bone cement to hip surgery, enabling total hip replacement to be practised on a larger scale. There is no question, however, that new approaches must be found to solving the problems of implant loosening, either by developing a new type of cement or by directly anchoring the implant without using ce ment. Much research has been done in this direction in recent years. The methods which have already been tested or are currently being tested were presented and discussed at a symposium on Cementless Fixation of Endoprostheses organized by the Orthopaedic Clinic of the University of Basel and held on 24-26 June 1982. Various possible ap proaches which might be realized in practice were discussed in a relaxed atmosphere. In addition to the biomechanical bases of cementless fixa tion of endoprostheses, the various models were discussed, with special regard to their biocompatibility, physical characteristics, design, clinical applicability, and previous clinical experience. This book contains the papers delivered at this symposium.

Modern endoprosthetics requires the examination of basic principles such as metallurgy, tribology, gait analysis, model and system development, methods of implant fixation, design, surface problems, material characteristics, stability behaviour, and operating techniques. With a background of more than 30 years of experience, this work presents a summary of these fields, providing the reader with the current state of knowledge. It is dedicated to Dr. med. h.c. Otto Frey-Zünd who, in conjunction with orthopaedic surgeons, scientists and engineers from all over Europe, developed artificial joints for hips, knees, elbows and wrists in over 30 years of pioneering work.

Hip and knee replacements are amongst the most frequently performed procedures and usually become necessarily due to age-related wear of the joint, osteoarthritis and fractures of the femoral neck. In light of demographic change, demands with regard to standards of care and the procedures are likely to rise. Contents • This White Paper contains information on indications, procedures, health economic aspects and the healthcare system stakeholders involved. • It portrays current developments with regard to the prevalence of hip and knee arthroplasty, the healthcare situation and quality of care within the chain of medical care. • This book is complemented by a chapter assessing the current situation from an expert perspective with contributions from renowned experts in the fields of science, medical technology and medical practice. This book addresses people involved in shaping and representing the healthcare system from a variety of fields including medical professions, health insurances and health sciences as well as journalists and patient representatives.

This book, a selection of the papers presented at the 32nd Japanese Hip Society (JHS) Congress, includes the latest knowledge on preservation and regeneration treatments of hip disease as well as arthroplasty. It is an invaluable source of reference for all who work in the field of orthopedic surgery.

This book presents analyses of the most commonly reported failure modes of hip stems: loosening and thigh pain; both are attributed to the relative motion and instability at the bone-implant interface due to failure to achieve sufficient primary fixation. The book investigates various factors that could affect primary stability and therefore the long-term outcome of hip arthroplasty. The results complement experimental work carried out in this area as in-vitro experiments have several limitations that could be addressed through computer simulations.

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 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.
