The surgical repair or treatment of degenerative joint disease has traditionally involved the substitution of synthetic materials for one or both surfaces of the joint. Engineering thermoplastics, metals, and ceramics have either been widely accepted or experimentally evaluated for use as bearing surfaces in these prostheses. When engineering thermoplastics are used, the opposing surface is a metal or a ceramic, but metal-on-metal, metal-on-ceramic, and ceramic-on-ceramic have also been used or tested. Researchers have sought the opportunity to utilize materials with compressive mechanical properties more closely matching those of the natural articular cartilage. This review discusses the theory, testing, and application of elastomers for one bearing component of articular joint prostheses.
传统上,退行性关节疾病的手术修复或治疗涉及用合成材料替代关节的一个或两个表面。工程热塑性塑料、金属和陶瓷已被广泛接受或经过实验评估,用作这些假体的承载表面。当使用工程热塑性塑料时,相对的表面是金属或陶瓷,但金属对金属、金属对陶瓷和陶瓷对陶瓷的组合也已被使用或测试。研究人员一直在寻找机会,利用抗压机械性能更接近天然关节软骨的材料。本文综述了弹性体在关节假体一个承载部件中的理论、测试和应用。
