A device and method for joint replacement surgery, such as total hip replacement surgery, including a bone cement plug which is adaptable to any size bone canal, an insertion tool for deploying the plug in the canal, and a cradle for storing the plug and insertion tool, The bone cement plug comprises a body defined by a series of separable units, each with a flange. The flanges decrease in diameter from the proximal end of the body to the distal end of the body. For smaller canals that cannot receive the large flanges, appropriate units of the plug may be removed, thus eliminating the oversized flanges in favor of the more appropriately sized flanges.
