摘要

The present invention relates to a cage assembly for spinal interbody fusion comprising: a main body inserted between a vertebral body of a spine in which a disc is removed, and a neighboring vertebral body; a first screw unit which is formed on the top of the main body, and is formed in a spiral shape along a first direction heading outward from the center; a second screw unit which is formed on the bottom of the main body, and is formed in a spiral shape along a second direction heading outward from the center; and a space unit which is formed to penetrate the top and bottom of the main body, and enables bones forming the vertebral body and the neighboring vertebral body to be mutually fused.
