The present invention relates to a vertebral cage, wherein a vertebral cage inserted between a vertebral bone and a vertebral bone to be used for fusion of a vertebral bone is formed in a frame-shaped porous structure to secure a wide bone graft filling space, and both sides of the upper and lower sides It is formed as a plate-shaped body having elastic force between the edges, but by forming a wave-shaped plate-shaped spring integrally, the bone through dynamic stabilization that allows individual or overall fine movement against the axial compression force applied between the vertebral bones. The fusion can occur well, and the technical configuration is that the top, bottom, left and right sides are formed in a certain part of the open except for the edge, and the front and rear are formed in a porous structure that is blocked. A bone graft filling space is formed in the cage body that is inserted between the vertebral bone and the vertebral bone； And a plate-shaped body having elasticity, installed between an upper left edge and a lower left edge of the bone graft filling space of the cage body, and between an upper right edge and a lower right edge, respectively, and one end and the other end thereof are the front surface of the cage body. And a plate-shaped spring extending in a horizontal direction so as to be integrally connected to the inner side of the rear surface, and being deformed by allowing a fine movement with respect to the axial pressing force applied to the cage body. Including, characterized in that it is manufactured by 3D printing.본 발명은 척추 케이지에 관한 것으로서, 척추 뼈와 척추 뼈 사이에 삽입되어 척추 뼈의 유합에 사용되는 척추 케이지를 프레임 형태의 다공성 구조로 형성하여 넓은 골 이식 충전공간을 확보하고, 상부와 하부의 양측 가장자리 사이에 탄성력을 갖는 판상체로 형성되되, 웨이브(Wave) 형태의 판상 스프링을 일체로 각각 형성하여 척추 뼈 사이에 가해지는 축성 압박력에 대하여 각각 독립적 또는 전체적으로 미세한 움직임을 허용하는 역동적 안정화를 통해 골 유합이 잘 일어나도록 할 수 있으며, 그 기술적 구성은, 상부면, 하부면, 좌측면 및 우측면이 가장자리 부분을 제외한 나머지가 일정부분 개방형성되고, 전면 및 후면이 폐색되는 다공성 구조로 형성되되, 내부에 골 이식 충전공간이 형성되며, 척추 뼈와 척추 뼈 사이에 삽입되는 케이지 본체； 및 탄성력을 갖는
