1995年，作者报道了一种独特的无水泥全髋关节，将羟基磷灰石（HA）火焰涂层应用于多孔钛表面，并在常压氩气中用纯钛材料电弧喷涂。该多孔层的表面粗糙度为360微米Rmax，比传统的低压等离子喷涂多孔层更耐爆炸侵蚀。考虑到羟基磷灰石的骨传导作用和层与多孔钛机械脱离的风险，羟基磷灰石层的厚度在20 ~ 40微米之间。短期动物试验显示了良好的效果。当时提出了一个具体的问题，即涂覆的HA层是否会长期留在活骨中。对回收标本的观察结果表明，羟基磷灰石涂层层的厚度足以在植入后形成新骨，并且在促进新骨形成后几年内会被体内吸收。
In 1995, the author reported the development of unique cementless total hip joints applying hydroxyapatite (HA) flame coating onto a porous titanium surface which is arc-sprayed with pure titanium material in argon gas at atmospheric pressure. The surface roughness of the porous layer was 360 microm Rmax, and the layer was more resistant to blast erosion than the conventional low pressure plasma sprayed porous layers. The thickness of the HA layer was between 20 and 40 microns considering the balance of bone conduction effect of HA and the risk of mechanical detachment of the layers from the porous titanium. Short-term animal tests showed excellent results. At that time a specific question was raised as to whether or not the coated HA layers would remain in the living bone for a long time. The results obtained from observation of retrieved specimens show that the thickness of the HA coating layer is sufficient for new bone formation after implantation, and HA would be absorbed in the body within a few years, after contributing to the new bone formation.
