Abstract
An orthopedic device set, including: a plurality of intervertebral spacer elements, each spacer element having a different axial thickness from each other element, the axial thicknesses being selected to increase by an increment from one element to another; and an instrument for holding ones of the intervertebral spacer elements, the instrument comprising a shaft having a distal end, a selectively grasping subassembly for alternatively rigidly holding each spacer element at the distal end so that the spacer element cannot move relative to the instrument, and releasing the spacer element.

An orthopedic device set, comprising:
- a plurality of intervertebral spacer elements, each spacer element having a different axial thickness from each other element, the axial thicknesses being selected to increase by an increment from one element to another;
- and
- an instrument for holding ones of said intervertebral spacer elements, the instrument comprising a shaft having a distal end, a selectively grasping subassembly for alternatively rigidly holding each spacer element at the distal end so that the spacer element cannot move relative to the instrument, and releasing the spacer element;
- wherein each spacer element is cylindrical and includes an annular groove, such that each annular groove defines a central cylindrical axial core, the axial cores of each spacer element having equivalent diameters, and the holding instrument can engage each spacer element by its axial core.
