1. A bone cement mixing and dispensing system for mixing and delivering bone cement therefrom, the system comprising:
a mixing container for holding a bone cement mixture, the mixing container extending along an axial length and having opposed first and second ends, the first end comprising a downstream opening for dispensing the bone cement from the mixing container;
a mixing element movably disposed within the mixing container;
a plunger comprising a piston movably disposed within the mixing container
a motor for driving the mixing element along the axial length of the mixing container;
a control for the motor which controls driving of at least one of the plunger and the mixing element,
wherein
the control senses a position of the mixing element and controls positioning of the mixing element along an entire travel of the mixing element along the axial length of the mixing container by sensing a position of the mixing element.
