A system and method for mixing bone cement. The components forming the cement are contained in a cartridge. A motorized device, such as a surgical handpiece, rotates a blade in the cartridge that mixes the cement. The current drawn by the motor is monitored. The current draw is evaluated to determine the viscosity of the cement. If the current draw indicates that the cement is at the target viscosity, the mixing may be terminated. A low current draw measure may be interpreted as an indication that the cement is of low viscosity and that it may be necessary to continue the mixing process.
