Claims20
A polyaxial endplate assembly, comprising:
- a locking member comprising a neck portion extending from a rounded head portion, the neck portion comprising a tapered slot extending therethrough;
- an articulable plate member comprising a plate portion extending from a rounded compressible body portion, the rounded compressible body portion defining a cavity configured to receive the rounded head portion of the locking member therein and an aperture configured to receive the neck portion of the locking member therethrough;
- a receiving member comprising an axial conduit comprising a constant diameter section and a variable diameter section, first and second tapered holes defining a tapered channel which intersects the conduit, and a receptacle which intersects the tapered channel, wherein the variable diameter section is configured to receive the rounded compressible body portion of the articulable plate member therein;
- a wedge member comprising a tapered transverse cross section and configured to be received within the channel of the receiving member;
- and
- a securing element configured to be received within the receptacle of the receiving member, wherein the securing element directly abuts the wedge member.
