Claims17
An expandable vertebral implant assembly comprising:
- an inner member;
- an outer member;
- a gear member, wherein rotation of the gear member causes relative movement between the inner member and the outer member;
- and
- a polyaxial endplate assembly attached to at least one of the inner member and the outer member
- wherein the polyaxial endplate assembly comprises an endplate, a securing element, and a clamping nut,
- wherein the securing element extends through the clamping nut towards a central longitudinal axis of the expandable vertebral implant assembly, and
- wherein the polyaxial endplate assembly is capable of pivoting along at least two intersecting axes disposed in the same plane which is not parallel to the central longitudinal axis.
