Anotácia

This specification covers self-curing resins used primarily for the fixation of internal orthopedic prostheses. While a variety of copolymers and comonomers may be incorporated, the composition of the set cement shall contain poly(methacrylic acid esters) as its main ingredient. The mixture may be used in either the predough or dough stage. This specification covers compositional, physical performance, and biocompatibility as well as packaging requirements. Materials shall be tested and shall conform to specified values of appearance, stability, sterility, viscosity, intrusion and compressive strength. The biocompatibility of acrylic bone cement as it has been traditionally formulated and used is also detailed.
