Abstract

The present invention relates to an intervertebral cage that is inserted into an extracted location to perform the function of a disk after a disk comprising the human spine has been extracted, comprising: a cage wherein a hollow part is formed to allow insertion of a bone chip inside; a tightening member fastening groove that is formed on the center of the outer wall of the cage; a first inclined hole that is inclined along the oblique line facing from the bottom side of the outer wall to the top side of the inner wall on one side of the tightening member fastening groove and has a jaw part formed on the internal diameter close to the inner wall; a second inclined hole that is inclined along the oblique line facing from the top side of the outer wall toward the bottom side of the inner wall and has a jaw part formed on the internal diameter close to the inner wall; screws that are inserted into the first and second inclined holes; and a tightening member that is fastened to the tightening member fastening groove to fix the head part of the screw.
