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.
Claims12
A trial assembly, comprising:
- an expandable trial having an expandable tip assembly;
- the expandable tip assembly having an engagement portion;
- and
- an endplate trial having an upper surface for engaging with a vertebral body surface, the endplate trial configured to be coupled to the engagement portion of the expandable tip assembly,
- wherein the endplate trial includes a lateral undercut configured to reversibly and non-pivotably engage the engagement portion of the expandable tip assembly,
- wherein the endplate trial includes a vertical slot extending from the upper surface to the lateral undercut and dividing the endplate trial into first and second deflectable portions containing respective first and second portions of the lateral undercut, such that the first and second portions of the lateral undercut are deflected to engage the engaging portion of the expandable tip assembly.

A trial assembly, comprising:
- an expandable trial having a handle and an expandable tip;
- the expandable tip capable of expanding in height and having an engagement portion in the shape of a circular disc;
- and
- an endplate trial configured to be coupled to the engagement portion of the expandable tip,
- wherein the endplate trial is configured to reversibly and non-pivotably engage the engagement portion of the expandable tip,
- wherein the endplate trial includes a lateral undercut for receiving the circular disc of the expandable tip, the undercut having a rear circular portion to receive the circular disc,
- wherein the endplate trial includes a pair of deflectable arms each having a prong that protrudes into the lateral undercut such that the distance between the prongs in an undeflected state is smaller than the diameter of the circular disc to maintain the circular disc between the prongs and the rear circular portion, the prongs shaped to passively deflect when the endplate trial is pulled away from the circular disc in order to allow removal of the endplate trial from the circular disc.
