摘要: An intervertebral implant has two U-shaped inserts set over each other with a center piece in between. The two inserts each have an opposing base surface, two lateral side surfaces, and a contact surface. The contact surface has a channel configured to receive a spinal process of a vertebral body. The center piece has two resting surfaces corresponding respectively to each contact surfaces. The contact and resting surfaces each have corresponding structures that can engage each other such that the U-shaped inserts can each be fastened in a detachable manner to the center piece. The U-shaped inserts each have on the same lateral side surface connecting means to fasten the inserts to gripping elements of a surgical instrument. And the first and second structures can be engaged or disengaged only by the lateral side surface fitted with the connecting means.
