对一种新型多孔陶瓷材料进行了测试，以确定其是否可用作主要暴露于压缩力的区域的骨替代物。将多孔陶瓷植入4只绵羊胫骨内侧髁，并放置3个月。然后取出手术胫骨，并对植入物进行切片。通过透射光显微镜、显微放射照相术和扫描电子显微镜对切片进行研究。有没有明显的功能丧失的手术腿和植入物被发现绑定到相邻的骨的骨组织向内生长，在某些区域的深度为2-3毫米。可以得出结论，多孔陶瓷植入物的性能证明了临床试验，只要长期动物实验的结果同样令人满意。
A new porous ceramic material was tested for possible use as a bone substitute in regions exposed mainly to compressive forces. The porous ceramics were implanted into the medial condyle of the tibia of four sheep and left in position for 3 months. The operated tibia was then removed and sections were made of the implants. The sections were studied by transmitted light microscopy, microradiography and scanning electron microscopy. There was no apparent loss of function of the operated leg and the implants were found to be bound to the adjacent bone by ingrowth of bony tissue, in some regions to a depth of 2-3 mm. It is concluded that the properties of the porous ceramic implants justify a clinical trial, provided that the results of long-term animal experiments are equally satisfactory.
