Elemental analysis by neutronic radioactivation for biocoral resorption and apatite formation versus time studies after implantation in vivo

摘要

Previous works carried out on coral show the advantages presented by this bio material used in bony surgery. Its resorbability is due to its bio compatibility and chemical properties. In our laboratory, we have studied the physico-chemical properties, the ossification kinetics and the calcification mechanism of the bio coral. By nuclear radioactivation, we have determined the amounts of Ca, P, Mg, Sr in natural coral, and their variations versus time after implantation in the metaphysis femur. The analysis of these atomic elements allows the study of coral resorption and apatite formation kinetics in coral, in cortical and in spongy bone with two different animal species.
