Claims18
A method of determining the orientation of an implant placed between two vertebral bodies, comprising the steps of:
- viewing the implant from a first aspect;
- and
- determining the orientation of the implant based on the orientation of a first radiopaque marker located on a first side of the implant and a second radiopaque marker located on a second side of the implant, the second marker opposing the first marker,
- wherein in an aligned orientation, only one of the first and second markers is visible from the first aspect.
