中文摘要
髋关节置换术的平均寿命为15-20年,之后需要进行翻修手术。翻修手术是不可取的,有问题的,而且不如初次置换成功。问题是目前的种植体保护宿主骨质量的能力不足,因此不能充分地将翻修种植体固定到位。本研究的目的是为全髋关节置换术植入物开发一种新型的材料微观结构,该材料可以持续更长时间,保持宿主骨的质量,并提供稳定的植入物固定。提出的材料是钛合金,Ti-6AL-4V,晶格;其突破性的标志在于材料性能的可控梯度,其设计与骨骼的局部特性相匹配,并提供前所未有的弹性和强度特性,以及卓越的疲劳,损伤和耐磨性。新型假体将加强对需要初次和翻修髋关节置换术患者的治疗,降低翻修手术的需要和相关的医疗保健费用;如果进行整形手术,将提高手术成功率。
英文摘要
On average, hip-replacements have a life span of 15-20 years, after which revision surgery is necessary. A revision surgery is undesirable, problematic and less successful than a primary replacement. Problematic is the inadequate capacity of current implants to preserve the quality of the host bone, which thus cannot sufficiently secure the revision implant into position. The aim of this research program is to develop a novel material microstructure for a total hip arthroplasty implant which can last longer, maintain the quality of the host bone, and provide a stable implant fixation. The proposed material is a titanium alloy, Ti-6AL-4V, lattice; its groundbreaking hallmark lies in the controlled gradients of material properties which are designed to match the local properties of the bone and provide unprecedented elastic and strength properties as well as superior fatigue, damage and wear resistance. The new implant will enhance the treatment of patients requiring primary and revision hip replacement, lower the need of revision surgery and the related health care cost; in case of revision surgeries, it will increase its success rate.
