Abstract
After total hip replacement with Sivash’s implants marked metallosis by chromium, cobalt and to a lesser degree by molybdenum develops in tissues contiguous with the joint. Titanium and tin are also determined in considerable amounts. At experimental (2 months to 5 years) and clinical (3 weeks to 15-19 years) follow up all metals are determined in the connective tissue. In bone tissue only small amounts of metals were present even in long term follow up. In short terms metallosis develops in the zones close to the mobility unit and gradually distributes along the bone marrow canal. As shown by experimental data metallosis is detected only as traces when the implant without friction units is used. In stable and unstable implants the degree of metallosis was the same although its incidence was higher when loosing developed. Our data confirm the possibility of the total hip prosthesis loosing but it develops gradually and manifest clinically in late terms.
