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
This open access book describes and illustrates the surgical techniques, implants, and technologies used for the purpose of personalized implantation of hip and knee components. This new and flourishing treatment philosophy offers important benefits over conventional systematic techniques, including component positioning appropriate to individual anatomy, improved surgical reproducibility and prosthetic performance, and a reduction in complications. The techniques described in the book aim to reproduce patients’ native anatomy and physiological joint laxity, thereby improving the prosthetic hip/knee kinematics and functional outcomes in the quest of the forgotten joint. They include kinematically aligned total knee/total hip arthroplasty, partial knee replacement, and hip resurfacing. The relevance of available and emerging technological tools for these personalized approaches is also explained, with coverage of, for example, robotics, computer-assisted surgery, and augmented reality. Contributions from surgeons who are considered world leaders in diverse fields of this novel surgical philosophy make this open access book will invaluable to a wide readership, from trainees at all levels to consultants practicing lower limb surgery

Book Description
Orthopedic experts in their field have carefully chosen what they consider to be the key papers in their respective domains. Every paper is carefully described and evaluated by its strengths, weaknesses and its contribution to the field. Papers have been chosen by number of citations, academic importance, articles that have changed our whole way of thinking or that have simply stood the test of time.

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.

Book Description
During the 2010 EFORT Congress in Madrid, many interesting topics relating to tribology in total hip arthroplasty were discussed during a special day devoted entirely to the subject. So successful was the day, and such was the broad interest in the discussions, that EFORT decided that publication of all the presentations would be warmly welcomed by fellow professionals who were unable to attend. This book is the result. It includes detailed information on the different articulating materials and the wear to which they are subject. The various factors that contribute to bearing performance and control wear are thoroughly evaluated, and careful consideration is given to the technology and design solutions proposed with a view to producing low-wearing hip joints. This book will be of interest both to novices who want to learn more about the field and to experienced orthopaedic surgeons wishing to keep abreast of the latest developments.

Book Description
The incidence of total hip arthroplasty is increasing in number because of successful outcomes. Although technically challenging, once mastered a hip replacement is one of the most gratifying surgeries for both patient and surgeon. This book covers some of the most important aspects of hip replacement surgery. These include preoperative planning, anesthesia, classification systems, management of proximal femur fractures, anterior approach, complications, and rehabilitation aspects of hip arthroplasty. The book is intended for arthroplasty surgeons, anesthetists, and physical therapists who will find the book useful in parts and as a whole if they deal with arthroplasty cases on a regular basis. Experience-based narration of various subjects by authors ensures that first-hand experience is passed on to readers in a simple, easy-to-understand manner.
