Book Description
The theme of this work is the application of the engmeermg theory of frictional torque to total hip replacement. The author adhered tenaciously to this theory, involving the use of a small-diameter femoral head, throughout the epoch when the large-diame ter, metal-to-metal design dominated the field. During that considerable period general satisfaction with the early results rendered criticisms of the large-diameter head unwelcome. There was a formidable array of counter criticism: the small head would pierce a film of synovial fluid; the small head would wear the socket too rapidly; the small head would always have a high risk of dislocation; detachment of the trochanter, to achieve precise orientation for the small head, was unacceptable. But all these objections have now been largely overcome. Lubrication of high molecular weight polyethylene (HMWP) on metal is now accepted as being mainly by the boundary regime with thick fluid films playing no part. We now know that HMWP can indeed tolerate the very high stresses imposed by the small head and in tribological theory there may even be some advantage in high stress. Dislocation is now known not to be an automatic sequel to the small head.

Book Description
This book reviews the principles and concepts underlying Professor Sir John Charnley’s original work Low Friction Arthroplasty of the Hip: Theory and Practice (Springer, 1979) in the light of more extensive clinical experience with results, incidence and indications for revisions highlighted throughout. The studies, combined with the examination of explanted components carried out with the backing of Universities, indicate the avenues for further research and the development and introduction of new ideas into clinical practice. The time span (1962 – 2015) involved has allowed a number of these very long-term studies not only to be brought to conclusion, but has given the benefit of their clinical application with meaningful results. This is not a sudden diversion into new and speculative areas of hip replacement surgery. It is a carefully collected, documented and executed work of the evolution of the Charnley low-frictional torque arthroplasty of the hip based on sound principles, supported by long-term studies with benefits derived.

Book Description
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.

Book Description
The 10th Congress of the European Federation of National Associations of Ort- paedics and Traumatology (EFORT) is the most important combined congress of the national societies in Europe. At present a total of 36 societies are members of this organisation. The major goal of EFORT is to bring current knowledge of diseases and trauma of the musculoskeletal system to all European surgeons and additionally to welcome colleagues from all over the world to join us in sharing our daily work experience. In the scienti? c programme the instructional lectures form a very basic and imp- tant part of the Congress. In Vienna a total of 25 sessions are included in the p- gramme. The authors come from all over Europe and they discuss topics from many different ? elds of trauma and orthopaedics. These lectures not only give the oppor- nity for us to be informed about various diseases, but they are also in? uenced by the authors’ experience based on the treatment philosophy in their own country – again an opportunity to widen the European horizon. They are aimed at both the general orthopaedic surgeons and the young residents and trainees who want to widen their knowledge in different topics of orthopaedic and trauma surgery. As the chairman of the Local Organising Committee I thank all the authors for providing their presentation for publication in this volume. I also address my special thanks to Professor George Bentley for organising this edition.

Book Description
UHMWPE Biomaterials Handbook describes the science, development, properties and application of of ultra-high molecular weight polyethylene (UHMWPE) used in artificial joints. This material is currently used in 1.4 million patients around the world every year for use in the hip, knee, upper extremities, and spine. Since the publication of the 1st edition there have been major advances in the development and clinical adoption of highly crosslinked UHMWPE for hip and knee replacement. There has also been a major international effort to introduce Vitamin E stabilized UHMWPE for patients. The accumulated knowledge on these two classes of materials are a key feature of the 2nd edition, along with an additional 19 additional chapters providing coverage of the key engineering aspects (biomechanical and materials science) and clinical/biological performance of UHMWPE, providing a more complete reference for industrial and academic materials specialists, and for surgeons and clinicians who require an understanding of the biomaterials properties of UHMWPE to work successfully on patient applications. The UHMWPE Handbook is the comprehensive reference for professionals, researchers, and clinicians working with biomaterials technologies for joint replacement New to this edition: 19 new chapters keep readers up to date with this fast moving topic, including a new section on UHMWPE biomaterials; highly crosslinked UHMWPE for hip and knee replacement; Vitamin E stabilized UHMWPE for patients; clinical performance, tribology an biologic interaction of UHMWPE State-of-the-art coverage of UHMWPE technology, orthopedic applications, biomaterial characterisation and engineering aspects from recognised leaders in the field

Book Description
The musculoskeletal system which comprises of different muscles, bones, and ligaments give support, stability, shape, and movement to the human body. The total number of bones in the skeletal system are 270 at birth and gradually reduce in number to 206 at adulthood due to fusion of few bones. Hip joint is amongst the largest of the weight-bearing joints after the knee and also one of the strongest joints. Usually, the average male femur is about 480mm in length with a diameter of 23.4mm. The hip joint is a classic example of a ball and socket joint where the head of the femur articulates in the acetabulum of the pelvis. The head of the femur and acetabulum are covered by a 63.5mm thick shiny white hyaline which acts as a smooth cushion to the joint. This joint has synovial fluid articulated in the mating surface which allows the joint to flex under different pressures without causing wear and tear. The synovial fluid and the hyaline help the bones move each other at different degrees of freedom without causing pain to the human. Usually, hip problems are associated with aged people due to worn-out hip joints. However, hip joint disorders can be associated with any person irrespective of age without proper care. Hip replacement surgery is considered to be amongst the greatest advances in health care of the twentieth century. In 1925 the first replacement made out of glass was used for the surgery by an American surgeon Marius Smith-Petersen. An American surgeon named Dr. Austin T. Moore at the Columbia Hospital, South Carolina performed the first metallic hip replacement surgery on September 28, 1940. Later, Sir John Charnley, who is considered the father of modern total hip arthroplasty, modeled a low friction arthroplasty in the early 1960s. This design was identical, in principle, to the prosthesis used in the present day. It consisted of a stem and head of the femur and an acetabular cup with a backing cup.
