The average creep strains of hand‐mixed cement, after 6 h of constant load, ranged from 0.11° at 10.5 MPa to 14.0° at 50 MPa of applied stress. Vacuum mixing reduced the average creep strain to 6.7° after 6 h of applied stress at 50 MPa. There were no significant differences in the creep response between the two types of acrylic cements.

Do we need to vacuum mix or centrifuge cement?

Conventional mixing of polymethylmethacrylate bone cement produces porosity of 5% to 16%, whereas vacuum mixing or centrifugation reduces the porosity to a range of 0.1% to 3.4%. Multiple studies have demonstrated that this results in a cement that has a significant increase in static and dynamic testing to failure.
