Polyetheretherketone (PEEK) has been widely used as substitute for metal in implants, especially in orthopedic surgery. Popular clinical applications of PEEK implants include interbody fusion and instrumentations in spinal surgery, component alternatives in joint arthroplasty, interference screws and fixation implants for osteotomy in sports surgery, and fracture implants for osteosynthesis. Several modification methods such as materials incorporation, surface treatments, and manufacturing processes are also available to overcome the bio-inertness of PEEK and improve its osseointegration and clinical performance. Furthermore, PEEK has prospective therapeutic applications as a carrier for bioactive agent and material for 3D printing. This short review summarizes recent studies and applications of PEEK materials in orthopedic surgery.

聚醚醚酮（PEEK）已被广泛用作植入物中金属的替代品，尤其是在骨科手术中。PEEK植入物的流行临床应用包括脊柱手术中的椎间融合和器械，关节置换术中的组件替代品，体育手术中用于截骨术的干涉螺钉和固定植入物以及用于骨合成的骨折植入物。还可以使用多种修饰方法，例如材料掺入，表面处理和制造工艺，以克服PEEK的生物惰性并改善其骨整合和临床性能。此外，PEEK作为生物活性剂和3D打印材料的载体具有前瞻性的治疗应用。这篇简短的综述总结了PEEK材料在骨科手术中的最新研究和应用。
