SELF-EXPANDING, ADAPTABLE CAVITY PLUG FOR USE IN IMPLANTATION OF ENDO-JOINT PROSTHESIS

摘要

The plug is designed for insertion in an opening formed in a medullated bone to act as a cement barrier. It comprises a polymeric material expandable in volume by uptake of water or temperature increase. The plug is capable of increasing its dimensions in the femoral cavity, adapting its shape to the geometry of the intramedullary canal and in consequence, closing the latter firmly. The self-adapting, expandable plug is produced from biocompatible expandable polymers.
