Abstract
An endplate for a vertebral implant comprises a base portion connectable to one end of a support body and a bone contact portion. The bone contact portion including a plurality of bone contact sections, each of which has a bone contact surface and extends from the base portion in such a way that each of the bone contact sections is deflectable relative to the base portion independently of an adjacent one of the bone contact sections when a compressive load is applied to the bone contact surfaces of the bone contact sections.

A vertebral implant, comprising:
- a support body;
- and an end plate pivotally connected to one end of the support body, the end plate comprising:
- a base portion connected to the support body;
- and a bone contact portion including a plurality of bone contact sections, each of the bone contact sections having a bone contact surface and extending from the base portion in such a way that each of the bone contact surfaces is deflectable relative to the base portion independently of an adjacent one of the bone contact surfaces when a compressive load is applied to the bone contact surfaces of the bone contact sections, wherein the end plate has a central opening with a recess formed near a proximal end of the bone contact sections, and wherein the support body comprises a pin extending through the central opening of the endplate, the pin having a head positioned in the recess of the end plate so as to allow the end plate to pivot relative to the pin.
