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.
Claims15
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 including an endplate, the endplate having a plate portion and a rounded body extending below the plate portion,
- wherein the endplate of the polyaxial endplate assembly is capable of pivoting along at least two intersecting axes disposed in the same plane which is not parallel to a central longitudinal axis of the expandable vertebral implant,
- wherein the polyaxial endplate assembly includes a receiving member attached to at least one of the inner member and the outer member, a locking member having a locking body disposed behind the rounded body of the endplate, a wedge member configured to be received in the receiving member, and a securing element configured to be received in the receiving member,
- wherein the securing element abuts the wedge member, and
- wherein the endplate is capable of pivoting with respect to the receiving member,
- wherein the securing element is adapted to push the wedge member to apply pressure against the locking member such that the locking body presses the rounded body of the endplate against an internal surface of the receiving member.
