Abstract: The changes of the interfaces and structures after the poly D, L-lactic acid/hydroxyapatite composite is planted into rabbits are studied. The changes of bone-formation and degradable capability of tissue and structure at different time after the composite in planted into rabbits are discussed via SEM measurements.

Key words: poly-D, L-lactic acid, hydroxyapatite, planted-material
