Abstract
Embodiments herein are generally directed to vertebral implants and implant trials for use with vertebral implant assemblies. In some embodiments, these implants and implant trials may be used in conjunction with corpectomy procedures.
Claims10
A method of installing a vertebral implant assembly, the method comprising:
- providing a vertebral implant assembly comprising:
- an inner member;
- an outer member;
- a gear coupled to the inner and outer members and adapted to move the inner member relative to the outer member upon rotation of the gear;
- and
- a polyaxial endplate assembly attached to at least one of the inner member and the outer member, and including:
- an upper endplate including a circumferential inner surface and a curved exterior surface and a plurality of gear teeth circumferentially arranged on the curved exterior surface;
- a mating body including a curved inner surface and mating teeth arranged circumferentially on the curved inner surface, the mating teeth enmesh with the gear teeth of the endplate;
- and
- a clamp disposed to press the endplate relative to the mating body to fix the endplate to the mating body at a desired angle, the clamp having a convex surface configured to contact the circumferential inner surface of the endplate;
- and
- a clamping screw coupled to the mating body and the clamp;
- expanding the vertebral implant assembly from a first height to a second height;
- and
- locking the upper endplate in a particular angular position relative to the mating body.
