Document Type and Number:
WIPO Patent Application WO/2023/085236
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a bone joint material which has high strength and a proper decomposition rate and can be bent with hands; and a method for producing the bone joint material. The present invention is a bone joint material which is used for fixing a bone at a bone fracture site, the bone joint material being composed only of poly-L-lactic acid, having bending resistance of 10 N or more at 37°C, and having bending resistance of 5 N or less at 70°C.
