SURFACTANT-CONTAINING BONE CEMENT

摘要

The invention relates to a bone cement based on PMMA, comprising a liquid component and a solid component, whereby said liquid component contains 50 - 85 wt. % of monomeric methylmethacrylate, 5 - 50 wt. % of surfactant, 0.2 - 5 wt. % of an accelerator and optionally small amounts of other adjuvants. Said invention also relates to the use of non-ionic surfactants, such as sorbitan monolaurate, sorbitan monooleate, polyoxyethylene sorbitan monostearate, polyoxyethylene sorbitan monooleate or polyoxyethylene sorbitan trioleate in PMMA bone cements containing active substances, for an improved release of antibiotic agents.
