The authors present in this brief note a technique to facilitate the introduction of high viscosity bone cement into a cement syringe for retrograde high pressure cementing during total hip or revision knee arthroplasty. The nozzle part of the syringe is connected to the suction device used intra-operatively, to achieve a negative pressure in the syringe. Introduction of the cement into the syringe is thus greatly facilitated, which saves time during the curing process.
