The need for quick, accurate, and reproducible methods to measure the amount of bone within porous metals has increased as the use of these materials has become more common within orthopedics. The purpose of this paper is to compare measurements of bone ingrowth using microradiography, stained histology, and backscattered electron imaging-scanning electron microscopy (BEI-SEM) in cementless, porous-coated acetabular components retrieved from human patients. BEI-SEM of bone ingrowth into porous metal provided excellent images for quantitative analysis. The stained sections and BEI-SEM images provided very comparable results, while microradiography consistently underestimated the porosity of the porous coating and overestimated the amount of bone ingrowth.
随着这些材料在骨科领域的应用日益普遍，对于快速、准确且可重复的方法来测量多孔金属内骨量的需求也在增加。本文的目的是比较使用微放射摄影术、染色组织学以及背散射电子成像-扫描电子显微镜（BEI-SEM）对从人类患者体内取出的非骨水泥型多孔涂层髋臼组件中的骨长入情况进行的测量。多孔金属中骨长入的BEI-SEM为定量分析提供了出色的图像。染色切片和BEI-SEM图像提供了非常可比的结果，而微放射摄影术始终低估了多孔涂层的孔隙率并高估了骨长入量。
