Abstract
An expandable intervertebral implant includes a base body, a top endplate and a center component. The top endplate is configured to be placed onto an open top of the base body and to expand upward. The top endplate includes a plate, first and second side protrusions extending vertically downward from first and second sides of the plate, respectively, first and second protrusions including inclined surfaces and extending obliquely downward from a first end of the plate and third and fourth protrusions having a triangular shape with at least one inclined surface and extending downward from a second end of the plate. The center component is configured to be placed within the base body and to interface with the top endplate and to move longitudinally forward or backward within the base body, thereby causing the top endplate to expand upwards or move downward, respectively.
