Potential of ceramic materials as permanently implantable skeletal prostheses
TL;DR: High-fired calcium aluminate samples in the form of quarter-inch diameter cylindrical pellets containing interconnecting porous networks were implanted in vivo into canine femurs for 4, 11, and 22-week periods, showing the ceramic samples to be bound lightly by natural bone and gave no detectable signs of tissue incompatibility.
