聚酯基材料是制造骨固定器械和常规临床使用器械的既定选择。本文综述了研究人员已经采取的方法来开发这些材料,以改善其机械和生物性能。聚合物共混,共聚,以及使用颗粒和纤维生物陶瓷材料,使复合材料和表面改性都进行了研究。聚合物共混、共聚和颗粒复合材料方法已在商业上采用,主要关注影响体内降解速率。在新型聚合物共混物和纳米级颗粒系统中出现了新的机会,可以调整整体性能,并在表面功能化方面优化器械与植入环境的初始相互作用,从而有可能改善骨折固定器械的临床性能。
Polyester-based materials are established options, regarding the manufacturing of bone fixation devices and devices in routine clinical use. This paper reviews the approaches researchers have taken to develop these materials to improve their mechanical and biological performances. Polymer blending, copolymerisation, and the use of particulates and fibre bioceramic materials to make composite materials and surface modifications have all been studied. Polymer blending, copolymerisation, and particulate composite approaches have been adopted commercially, with the primary focus on influencing the in vivo degradation rate. There are emerging opportunities in novel polymer blends and nanoscale particulate systems, to tune bulk properties, and, in terms of surface functionalisation, to optimise the initial interaction of devices with the implanted environment, offering the potential to improve the clinical performances of fracture fixation devices.
