As a new kind of material for peripheral osteosynthesis we have developed the single crystal alumina ceramics screws (artificial sapphire screws) taking under consideration of the properties of alumina ceramics, and we have tested them experimentally in animals, and used them clinically too. The results of the mechanical tests and animal experiments were excellent. In the clinical follow-up studies the perfect bone unions has been recognized roentgenologically. The sapphire screws have, sofar, proved to be harmless also as anchor for bone cement. Our experience with our sapphire screws has opened the way for the clinical application of this material instead of metal screws.
作为一种用于外周骨固定的新型材料，我们根据氧化铝陶瓷的特性开发了单晶氧化铝陶瓷螺钉（人造蓝宝石螺钉），并在动物身上进行了实验测试，也将其应用于临床。力学测试和动物实验的结果都非常出色。在临床随访研究中，通过X射线检查确认实现了完美的骨愈合。到目前为止，蓝宝石螺钉作为骨水泥的锚定物也被证明是无害的。我们在蓝宝石螺钉方面的经验为这种材料替代金属螺钉的临床应用开辟了道路。
