Abstract
A system that includes a cervical plate and an intervertebral cage, the cervical plate having a mounting section that renders the cervical plate mountable to a reference feature located on the front wall of the intervertebral cage, the reference feature being positioned to set a distance between an eyelet of the cervical plate and an edge of the front wall to position the eyelet over a mounting location on a vertebra when the mounting section is mounted to the reference feature.
Claims7
A system comprising an intervertebral cage and a cervical plate configured to be mounted to said intervertebral cage, said intervertebral cage having a front wall, the cervical plate comprising a body having a top edge, a bottom edge and two side edges, at least one top eyelet located along said top edge, at least one bottom eyelet located along said bottom edge, a mounting section located between said top eyelet and said bottom eyelet, the mounting section being configured to be mounted to a corresponding reference feature at said front wall of said intervertebral cage, said reference feature being located in a position to set a distance between one of said at least top eyelet and said at least bottom eyelet and an edge of said front wall to position at least one of said eyelets over a mounting location on a vertebra when said mounting section is mounted to said reference feature;
- another mounting section configured to be mounted to said reference feature at said front wall of said intervertebral cage, said reference feature being located in a position to set another distance between one of said at least top eyelet and said at least bottom eyelet and an edge of said front wall to position at least one of said eyelets over a mounting location on a vertebra when said another mounting section is mounted to said reference feature, said another distance being different than said distance;
- a fixation component that includes a screw receivable in an opening defined in said mounting section and a hole defined in said front wall to mount said cervical plate to said cage;
- and
- a drill guide having at least one cannula configured to register with at least one of said eyelets, wherein said fixation component is supported by said drill guide at a location spaced from said cannula,
- wherein said opening of said mounting section includes a slot and said another mounting section includes a slot.
