A bone cement loading system is provided to load the components in the mixing cartridge, while a rotary power tool (177) or a mixing handle can be selectively, interchangeably, and operatively connected to the mixing device to mix the components once loaded. A converter can also be used to convert rotational input from the rotary power tool into rotational and axial output to simplify mixing of the components. After mixing, the cartridge is placed in the delivery gun. The delivery gun comprises a drive rod having a plurality of teeth (780).
