Presenting recent advances in clinical diagnosis and treatment derived from an increased understanding of the biology of the hip, this unique text examines hip disease and pathophysiology through the lenses of kinematics, biomechanics, anatomy and metabolism. Opening chapters examine the impact of health care organization on hip care and prevalence and burden of osteoarthritis.Biomechanical considerations of the hip and gait pathomechanics in hip disease are then discussed, followed by chapters covering femoroacetabular impingement, possible links between OA and metabolic syndrome, osteonecrosis, osteoporosis and Paget's disease. Considerations of risk reduction surrounding hip arthroplasty conclude the text, including device and surgical options for THA, hip sepsis and prevention of perioperative infection, and management of venous thromboembolism. Taken together, this represents a new and important context for the discussions and management of hip disease for orthopedic surgeons and researchers alike.
