PURPOSE:To provide the internal fixing material for joining bone which can eminently accelerate the initial formation of bone by an excellent piezoelectric property and has high safety of biodegradation absorptivity in the linking body CONSTITUTION:This interior fixing material is constituted by uniaxially stretching the molten molding of polylactic acid within a range where the fibrillation thereof does not arise in such a manner that the piezoelectric constant-d'14 thereof attains 8 to 13(pC/N),-e'14 attains 10 to 20(mC/m<2>). |
