A bone cement plug for use in conjunction with bone cement dispensers to compact bone cement into bone canals during total joint replacement surgeries. The bone cement plug includes a core including a substantially cylindrically-shaped base portion defining a threaded bore therein extending axially and distally from a proximal end of the base portion; a first leg portion depending from and extending distally from the base portion; and a second leg portion depending from and extending distally from the base portion and opposed to the first leg portion; the base portion threaded bore being adapted to receive an expander screw to wedge apart the first and second leg portions, whereby to expand the core widthwise to secure the plug in the bone canal; and the expander screw, the screw comprising a generally cylindrically-shaped body having a tapered distal end, and a proximal end in which is disposed a threaded bore, external threads disposed on the body, and an annular flange extending outwardly from the proximal end of the body, the screw being threadedly engageable with the core threaded bore for advancement of the screw into the plug for the wedging apart of the first and second legs. A method is also disclosed for using the bone cement plug to compact bone cement into a bone canal during total joint replacement surgeries.
