Abstract

Although mechanical property characterization of materials for loadbearing implant applications is recognized as a necessary prerequisite to their in vivo use, tests are usually restricted to in vitro situations becaus-of specimen size and cost limitation. Thisstid7'Jescribes a fracture toughness test that uses small specimens that can be conveniently placed in intermuscular positions in laboratory rats. The method is illustrated for the evaluation of two orthopaedic biomaterials namely bone cement and a filled composite (hydroxyapatite-filled polyethylene). The results indicated little mechanical degradation of the bone cement after 120 days in vivo but a significant change in the filled polyethylene composite after only 70 days in vivo.
