Notes:
Total hip replacements are based on a long chain of efforts of partial exchange of joint compartments. Inplants of material of both biological and nonbiological origin have been applied over the past 50 years. Smith-Pedersen, Judet, Moore, and Thompson are names to be remembered. It was primarily from the idea of firm fixation and low friction between the joint surfaces that today's constructions emerged. Immediate superior clinical results encouraged a strong trend towards hip-arthroplasties. The orthopedic surgeon can now choose amongst several prosthetic designs, the most common being metal to metal or plastics with or without bone cement. But, after ten years a number of threatening problems have become evident, calling for critical analysis of total joint replacements. Biomechanical, chemical, and morphological disturbances, both in the early and late phases, show that the body has difficulties in tolerating the artificial joint. This survery presents some of the most obvious risks and failures in total hip replacements.
