  • Re: Spine - PMMA

    I don't like the PMMA vertebroplasty, for several reasons, but the best
    way to extend the working time for PMMA is to either :
    1. use Low Viscosity cement (Zimmer LVC is one of the slowest).
    2. Chill the *monomer only* before mixing.
    Do not freeze, just a standard household refrigerator is fine.
    Lower the theatre temperature too, if you can.
