title: [Experience of peripheral osteosynthesis using single crystal alumina ceramics screws (author's transl)].
abstract: 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.
