Claims19
A polyaxial endplate assembly, comprising:
- an articulable plate having an end plate and a rounded compressible body extending below the endplate and overlying a round surface of a receiving member of an implant, the body being articulable relative to the receiving member;
- a clamp assembly, having a first clamp member and a second clamp member, disposed circumferentially around and over the body of the articulable plate, the clamp assembly having a receptacle, a fastener received in the receptacle, and a round surface configured to press the body of the articulable plate against the round surface of the receiving member to clamp the articulable plate to the receiving member with the fastener,
- wherein each of the first and second clamp members has a thickness between the interior surface and an exterior surface, and the thickness at an end of each clamp member is less than the thickness at a central portion of each clamp member.
A polyaxial endplate assembly, comprising:
- an articulable plate having an end plate and a rounded compressible body extending below the endplate and overlying a round outer surface of a receiving member of an implant, the body being articulable relative to the receiving member;
- a clamp assembly including first and second clamp members each including a central receptacle and an interior surface, the clamp assembly disposed circumferentially around and over an outer surface of the body of the articulable plate;
- a fastener coupled between the first and second clamp members, the fastener adapted to press the first and second clamp members against the body of the articulable plate to clamp the articulable plate to the receiving member,
- wherein each of the first and second clamp members has a thickness between the interior surface and an exterior surface, and the thickness at an end of each clamp member is less than the thickness at a central portion of each clamp member.

A polyaxial endplate assembly, comprising:
- an articulable plate having an end plate and a rounded body extending below the end plate, the body having a plurality of tabs and defining a cavity therein;
- a clamp assembly including first and second clamp members each having an interior surface configured to engage the tabs of the articulable plate body and a central protrusion having a receptacle therein;
- a receiving member having a rounded portion configured to be received within the cavity of the body;
- and
- a fastener configured to be received within both receptacles of the first and second clamp members,
- wherein each of the first and second clamp members has a thickness between the interior surface and an exterior surface, and the thickness at an end of each clamp member is less than the thickness at a central portion of each clamp member.
