Cement Mixing Technique for TJR

- See: Addition of Antibiotics to Cement

- Discussion:
    - full discussion of technique for cementing femoral stems
    - mixing under vacuum reduces retained air & incr cement strength;
    - typically 2 bags are needed;
    - slower mixing of cement over a shorter time decreases air voids within cement and thus improves the strength characteristics;
    - characteristics of cement are markedly improved by centrifugation.
           - 24% increase in ultimate tensile strength;
           - 54% improvement in mean ultimate tensile strain;
           - 136% increase in mean fatigue life;
    - vaccum mixing:
