A trial spacer comprising:
- a spacer body configured to be positioned between vertebrae of a subject;
- and
- depth indicia disposed in the spacer body, each of the depth indicia comprising a numerical value and designed and constructed to indicate a distance from a distal end of the spacer body to a corresponding one of the depth indicia, wherein the depth indicia are radiographically visible when the spacer body is positioned between the vertebrae of the subject, wherein the depth indicia are enclosed within the spacer body and not visible without radiographic imaging, and wherein a portion of the spacer body is more radiolucent than the depth indicia so that the depth indicia are radiographically visible.
A trial spacer comprising:
- a spacer body configured to be positioned between vertebrae of a subject;
- and
- a sizing indicium disposed in the spacer body, the sizing indicium comprising a numerical value and designed and constructed to indicate a size of the trial spacer,
- wherein the sizing indicium is radiographically visible and readable when the spacer body is positioned between the vertebrae of the subject, and
- wherein the sizing indicium is disposed in a window extending through the spacer body such that the sizing indicium is also visible and readable without radiographic imaging.
