ABSTRACT:
The cavity of the stem of the tumor or re-operation prosthesis is subdivided by support elements into sub-cavities filled with bony material. The support elements are formed with central apertures through which the bony material can be supplied and re-vascularized from the living bone tissue of the femur stump. Wire mesh may cover over the apertures in the support elements as well as the slots between the circumferentially disposed webs which define the cavity of the stem.
