<P>PROBLEM TO BE SOLVED: To provide a shaped article for bone treatment and an implement for bone treatment with high tensile strength and torsional strength, for which a biodegradable polymer is a constituting material, and a shaped article for bone treatment and an implement for bone treatment with high bending strength, tensile strength and biodegradability, for which a biodegradable polymer is a constituting material. <P>SOLUTION: The shaped article for bone treatment is composed of a biodegradable polymer and the degree of the orientation of a molecule chain or the long axis of a crystal has distribution from the center part to the outer peripheral part. The manufacturing method of the shaped article for bone treatment for drawing a preliminary shaped article composed of the biodegradable polymer is characterized by that the temperature of the preliminary shaped article in a drawing area has the distribution from the center part to the outer peripheral part of the preliminary shaped article. <P>COPYRIGHT: (C)2007,JPO&INPIT |
