Polymethylmethacrylate remains one of the most enduring materials in orthopaedic surgery. It has a central role in the success of total joint replacement and is also used in newer techniques such as percutaneous vertebroplasty and kyphoplasty. This article describes the current uses and limitations of polymethylmethacrylate in orthopaedic surgery. It focuses on its mechanical and chemical properties and links these to its clinical performance. The behaviour of antibiotic-loaded bone cement are discussed, together with areas of research that are now shedding light upon the behaviour of this unique biomaterial.
聚甲基丙烯酸甲酯仍然是骨科手术中最持久使用的材料之一。它在全关节置换的成功中起着核心作用，并且还用于诸如经皮椎体成形术和后凸成形术等较新的技术中。本文描述了聚甲基丙烯酸甲酯在骨科手术中的当前用途和局限性。它着重于其机械和化学性质，并将这些性质与它的临床性能联系起来。文中讨论了载抗生素骨水泥的行为，以及目前正在揭示这种独特生物材料行为的研究领域。
