Abstract

Dynamic compression plate, used in the orthopedic surgery as internal fixation system, should have excellent biocompatibility, corrosion resistance, and adequate mechanical properties. The object of this research was test of its biocompatibility as compared with Osteo DCP and fabnfication of a KAIST" DCP with evaluation of its effect by animal experiment. The conclusions were follows: 1. The corrosion resistance of domestic DCP had no significant difference as compared with foreign made DCP. 2. The tissue responses to DCP were thought to be adequate. 3. The new-design DCP had less mobility at fracture site as compared with existing DCP, but there was no significant statistical differences. 4. In summary, it was concluded that KAIST DCP could be applied to the human body and it would be worth while to research the advantages of new-design DCP.
