ABSTRACT:
A method and apparatus for removing a pre-placed prosthetic joint from a bone cavity and conditioning the cavity for receipt of a replacement joint. The pre-placed joint is first pulled from the mantle of hardened cement holding it within the cavity, thus leaving a cavity within the mantle. A mass of fluid cement is then placed within the cement cavity, after which a pulling appliance is inserted into the fluid cement and the fluid cement is permitted to cure to bond the appliance to the mantle. Tension is then applied to the pulling appliance to remove the appliance and the cement mantle from the bone cavity as a unit. The fluid cement partially dissolves and softens the hardened cement mantle so that an integral cement mass is formed upon curing of the fluid cement. The pulling appliance is of a screw-like configuration, with means to connect a slap-hammer to its proximal end.
