Abstract
The purpose of this study is to investigate a loosening process of screws through a fatigue test. Therefore, it is attempted to perform an interbody fusion on porsine lumbar spine using cage and screws. From the results, it is found that the combining force in both of the cylinder and the taper type screws located on the upper-left first start to decrease and then the combination between a rod and screw loosens. In addition, it is investigated that the life of taper type screw increases 5.5% and this fact is coincident with the previous results.
