cement preparation

Preparation of the cement:

This movie illustrates cement preparation. A package of methyl methacrylate (Simplex ® Howmedica, Osteopal V ® Biomet Merck, Palacos ® Biomet) low viscosity is composed of 20 g powder and 20 ml fluid monomer. The acrylic glue is obtained by mixing the two components. Then half of the glue is thrown away. 3g of tantalum are added to the mixture in order to increase the radiopacity of the cement.
