PURPOSE:To provide the bone joining device which has excellent initial strength and initial modulus of elasticity and with which the part coated with polylactic acid is absorbed in about several months after implantation into a living body, the probability of inducing an inflammation is extremely low, the cavity after absorption by the neobone is filled in an early period and the core material adapts itself to the biotissue, thereby the re-operation to draw out a mail is no need. CONSTITUTION:This bone joining material is constituted by using a molding of biode gradable polymer contg. 75 to 95wt.% respective independent materials of hydroxy apatite (HA), tricalcium phosphate (TC) and crystallized glass contg. HA and wallastonite or the mixture composed thereof as a core material and coating this core material with the polylactic acid. |
