The custom triflange is a patient-specific implant for the treatment of severe bone loss in revision total hip arthroplasty (THA). Through a process of three-dimensional modelling and prototyping, a hydroxyapatite-coated component is created for acetabular reconstruction. There are seven level IV studies describing the clinical results of triflange components. The most common complications include dislocation and infection, although the rates of implant removal are low. Clinical results are promising given the challenging problem. We describe the design, manufacture and implantation process and review the clinical results, contrasting them to other methods of acetabular reconstruction in revision THA.
定制三翼缘植入物是一种针对翻修全髋关节置换术（THA）中严重骨丢失治疗的个性化植入物。通过三维建模和原型制作过程，制造出一种用于髋臼重建的羟基磷灰石涂层部件。有七项IV级研究描述了三翼缘部件的临床结果。最常见的并发症包括脱位和感染，不过植入物取出率较低。鉴于该问题具有挑战性，临床结果很有前景。我们描述了其设计、制造和植入过程，并回顾了临床结果，将其与翻修THA中髋臼重建的其他方法进行对比。
