摘要 |
This invention relates to an orthopaedic composition comprising porous chitosan particles suspended in a liquid medium wherein the liquid medium further comprises a biocompatible polymer. The invention also provides a process for preparing a solid or semi-solid orthopaedic material by drying the orthopaedic composition. The resulting solid or semi-solid orthopaedic material finds use as a bone-replacement material, a bone cement and a tissue scaffold. A process for preparing suitable porous chitosan particles for the present invention by incorporating a porogen capable of including crystallinity is also described.
