Title:
THREE-DIMENSIONAL STRUCTURE CREATED FROM MATERIAL COMPRISING POLYHYDROXYALKANOATE, KIT FOR PREPARING BONE FILLING MATERIAL, AND INTRAMEDULLARY NAIL
Document Type and Number:
WIPO Patent Application WO/2013/146788
Kind Code:
A1
Abstract:
Provided is a material for preventing leakage of bone cement to outside the bone when a bone fracture site is filled in with the bone cement. The use of a three-dimensional structure created from a material comprising a polyhydroxyalkanoate in filling in a bone fracture site with bone cement makes it possible to prevent leakage of the bone cement to outside the bone.
