Apparatus and method for forcing flowable cement out of a container into a bone cavity under pressure for binding a prosthesis in the bone cavity with minimal bubbles and voids. The apparatus includes a first pressurization device such as a ratchet gun for forcing the flowable cement from a container of cement into the bone cavity in first increments. A second pressurization device then forces the flowable cement out of the container into the bone cavity in second increments smaller than the first increments to control the pressure in the bone cavity by causing it to increase in smaller increments than with the first pressurization device.
