An Animal Experiment for Domestic Production of Metallic Implant / 대한정형외과학회잡지

ABSTRACT

In Korea, the metallic implant had to be supplied through import channel with many problems. KAIST succeeded in making AISI 316 LVM stainless steel within the criteria of American Society for Testing and Materials. With the animal experiment at preliminary report I, the biocompatibility in the muscle was examined. For biocompatibility test of new material, test in the bone is essential. In this animal experiment using rat tibia, the biocompatibility of the Kirschner wire of KAIST was compared with that of Zimmer. The result was as follows 1. Tissue reaction of the Kirschner wire of KAIST was minimal to moderate. 2. Corrosion was negligible, and there was no definite difference between the KAIST and Zimmer Kirschner wires. 3. Authors observed the satisfactory biocompatibility of the KAIST Kirschner wite in bone and muscle, and concluded that the Kirschner wire of KAIST can be applied to human body without serious problems.
