SummaryThe mechanical strengths of four types of ingrown porous carbon and two types of porous metal bone implants were correlated with the type of osseous ingrowth into the porous interfaces. Intracortical cylinders were implanted into canine long bones and examined at 3, 6, and 12 weeks. Histological techniques were used to study hone ingrowth. Tetracycline labelling and electron microprobe analysis were used to characterize the degree of mineralization of the ingrowth. Shear strengths of bone-porous materi…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
