已经尝试测量骨与在其表面上具有开孔的植入材料的结合能力。在狗的陶瓷，Vitallium与缎面，和一种新型的多孔表面抛光Vitallium植入物的实验工作的结果。骨与多孔表面金属的牢固结合是通过新骨对多孔结构的主动渗透而建立的。这种多孔表面也大大增强了金属与甲基丙烯酸甲酯水泥的粘合。对于这种材料在外科手术中的可能用途，已经提出了一些建议。
An attempt has been made to measure the bonding capability of bone with implanted materials which have open pores on their surfaces. The results of experimental work in dogs with ceramics, Vitallium with satin surface, and a new type of porous surface finish for Vitallium implants is presented. Firm bonding of bones with the porous-surfaced metal was established by the active infiltration of the porous structure by new bone. Bonding of the metal with methylmethacrylate cement was also greatly enhanced by this porous surface. Some suggestions have been made as to the possible surgical use of such material.
