A core for forming a bone cement plug for deployment in a bone canal, the core including a base portion defining a bore having internal teeth therein and extending axially and distally from a proximal end of the base portion. A first leg portion depends from and extends distally from the base portion, the first leg portion having a first protrusion at a distal end thereof extending outwardly from an outside wall of the first leg portion through a first arc, and a second leg portion depends from and extends distally from the base portion, the second leg portion having a second protrusion at a distal end thereof extending outwardly from an outside wall of the second leg portion through a second arc and oppositely to the first arc. The toothed bore of the base portion is adapted to receive an expander member to wedge apart the first and second leg portions to expand the core widthwise to secure the core in the bone canal. |
