In total hip arthroplaysty (THA), accelerated wear is observed when third-body particles migrate into the bearing surface. Third-body particles can be bone cement, debris generated at modular connections or fragments from previous implant failures. All specimens are tested according to ISO 14242-1 using the EndoLab® hip joint simulator. Particle concentration, size and material (PMMA, ceramic, bone chip etc) is defined in cooperation with the customer. To maintain the third-body particle suspension in the test fluid, each test chamber is circulated by individual peristaltic pumps.
