了解力如何通过股骨近端分布对外科医生、研究人员和假体设计者有许多临床应用。开发了一种新的股骨表面应变二维分析系统，并将其应用于完整的复合材料股骨。光弹性涂层法被用来解决轴向载荷下的表面应变，应变分析是使用数字成像的应变模式和原始的计算机程序。该技术提供了定性和定量数据，比以前的点分析和应变计技术更完整地描述了整体股骨表面应变。重复测试的结果发现光弹性过程、计算机成像和应变区域的计算机分析在统计上是可重复的。
Understanding how forces are distributed through the proximal femur has many clinical applications for surgeons, researchers, and prosthetic designers. A new system for two-dimensional analysis of femoral surface strain was developed and applied to intact composite femurs. The photoelastic coating method was used to resolve the surface strain under axial loading, and strain analysis was performed using digital imaging of the strain patterns and original computer programs. The technique provides qualitative and quantitative data that describes overall femoral surface strains more completely than previous point analysis and strain gauge techniques. Results from repeated testing found the photoelastic process, computer imaging and computer analysis of strain areas to be statistically repeatable.
