1039716BuckleyIn accordance with the NSF-MRI initiative, Rose-Hulman Institute of Technology is seeking to expand biomechanical instrumentation available for students, faculty and associated collaborators conducting research projects in orthopaedics. Specifically, the goal is to obtain the instrumentation necessary to accurately apply physiological loading to cadaveric specimens implanted with orthopaedic devices, and to precisely quantify the mechanical conditions related to clinically observed failure of the implanted devices and/or tissue specimens. The requested coupled instrumentation system includes a biaxial servohydraulic materials testing machine with dynamic pressure and strain acquisition instrumentation. The goal of this project is for the validated study of hip and knee prosthesis design and its effect on the mechanical response and interactions between bone and implant, leading to the development of improved, cost effective design alternatives. The necessary facilities, infrastructure, and technical support are in place to immediately implement the requested instrumentation into existing laboratory space.

1039716巴克利根据NSF-MRI倡议，Rose-Hulman理工学院正在寻求扩大可用于开展矫形外科研究项目的学生、教师和相关合作者的生物力学仪器。具体地说，目的是获得必要的器械，以准确地对植入了矫形外科装置的身体标本施加生理载荷，并精确量化与临床观察到的植入装置和/或组织标本的失效相关的力学条件。所要求的耦合仪器系统包括一台带有动态压力和应变采集仪器的双轴伺服液压材料试验机。该项目的目标是对髋关节和膝关节假体的设计及其对机械响应和骨与植入物之间的相互作用的影响进行验证研究，从而开发出改进的、具有成本效益的设计替代方案。必要的设施、基础设施和技术支持已经到位，可以立即将所要求的仪器安装到现有的实验室空间中。
