Modern cementing techniques in total hip arthroplasty routinely include the use of cement restrictor plugs to occlude the femoral canal, which enable cement containment and help in pressurized cement application. Formation of emboli from within the intramedullary canal is of great concern. We investigated the insertion force profile and distal femoral canal pressurization as a result of the introduction of different sizes of cement restrictor plugs from three different manufacturers on artificial femora. No significant difference in insertion force profiles were observed for the different restrictors tested. However, the Stryker Howmedica cement restrictor plugs generated the highest pressure in the distal intramedullary canal.
