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.
