ABSTRACT:
A mantle of cement having an elongate cavity formed therein is removed from adhered condition within a bone recess by successively breaking away sections of the mantle with a plurality of elongate screw threaded pulling elements proportioned to engage a limited length of a screw threaded mass of cement received in the cavity. The apparatus of the invention is provided in kit form with sufficient elements to enable the full length of the mantle to be removed in successive steps. The kit may also include a cement injection syringe and vent tube to fill the cavity of the mantle with a mass of cement, a die to form a screw threaded passage in the mass of cement, and a slap hammer connectable to the pulling elements.
