ABSTRACT:
The medullary cavity barrier is made of a metal in a rosette manner with leaves which are permanently and elastically deformable. The barrier is porous to the extent of being permeable to blood, fat and gases but impermeable to the passage of bone cement. During implantation, each outwardly extending leaf bends relative to a central core to fix the barrier within a tubular bone.
