WebBone cements are provided as two-component materials. Bone cements consist of a powder (i.e., pre-polymerized PMMA and or PMMA or MMA co-polymer beads and or amorphous powder, radio-opacifier, initiator) and a liquid (MMA monomer, stabilizer, inhibitor). The two components are mixed and a free radical polymerization occurs of the monomer when ... WebPMMA bone cement is contraindicated in the presence of active or incompletely treated infection at the site where the bone cement is to be applied, for treatment of non-pathological, acute traumatic fractures of the vertebra or sacrum, and in cases involving either displaced sacral fractures or compromise of the sacral foramina.
WebINTRODUCTION PMMA is a versatile material and has been used in a wide range of fields and applications. The German chemist Fittig and Paul discovered in 1877 the polymerization process that turns Methyl Methacrylate into poly Methyl Methacrylate (Lovell 1997). PMMA is routinely produced by emulsion polymerization.
