| 摘要 |
A synthetic bone substitute (9) is disclosed comprising a porous foam structure comprising a bio-resorbable polymer and a bio-ceramic filler material wherein a plasticizer is used for softening the porous foam structure such that the synthetic bone substitute may be compressed by an external force. Due to its elasticity, the synthetic bone substitute may restore its original form after releasing the external force. Furthermore, due to dissipation of the plasticizer, the porous foam structure can attain substantial rigidity thereby functioning as lightweight, stable bone substitute. Such compressible bone substitute can be compressed, then inserted through a small opening hole to a cavity and once in a cavity restore its original volume and rigidity. |
