This book provides comprehensive, evidence-based surgical principles and techniques for total hip arthroplasty (THA), covering all aspects of this procedure, including the history, biomaterials, biomechanics, surgical techniques and other important issues. Beginning with an overview of the hip joint and its anatomy, the authors detail the biomechanics of the hip joint in its various states and further discuss the properties of biomaterials in arthroplasty. The book describes the principles of surgical technique, preoperative planning, surgical procedures, rehabilitation, and management of complications, and thoroughly illustrates surgical procedures to enhance the reader's understanding. The book also introduces the technical aspects of the procedure, including how to deal with difficult cases such as severely deformed cases and how to increase the safe range of motion. Advances in Total Hip Arthroplasty is written by a pioneering team of authors in cooperation with the Japanese Society for Replacement Arthroplasty (JSRA). The book is informative and provides practical tips for THA and academic insights for orthopedic surgeons and residents specializing in arthroplasty. The translation was done with the help of an artificial intelligence machine translation tool. A subsequent human revision was done primarily in terms of content.
