Abstract
A system may be configured for facet fixation and may include a cap configured to span a vertebral facet joint. The cap may include a distal surface configured to seat against a bone proximate the vertebral facet joint. The system may also include a fastener configured to secure the cap to the vertebral facet joint. The cap may include an indicator configured to move from a first position to a second position in response to engagement of the distal surface with the bone.
Claims25
A facet fixation system, the system comprising:
- a cap configured to span a vertebral facet joint, the cap comprising a distal surface configured to seat against a bone proximate the vertebral facet joint;
- and
- a fastener configured to secure the cap to the vertebral facet joint;
- wherein the cap comprises an indicator configured to move from a first position to a second position in response to engagement of the distal surface with the bone.
The system of claim 1, further comprising a reamer configured to prepare a bone surface for implantation of a facet fixation device, the reamer comprising a cutting head comprising a plurality of cutting edges, wherein the cutting head is configured to cut in a clockwise direction and a counter-clockwise direction.
A facet fixation system, the system comprising:
- a cap configured to span a vertebral facet joint;
- a fastener configured to secure the cap to the vertebral facet joint;
- an inserter configured to engage the cap;
- and
- a lock that is moveable, relative to the inserter, between a locked position, in which the cap is not disengageable from the inserter, and an unlocked position, in which the cap is disengageable from the inserter.
A facet fixation system, the system comprising:
- a cap configured to span a vertebral facet joint, the cap comprising a distal surface configured to seat against a bone proximate the vertebral facet joint, and a proximal surface facing proximally;
- and
- a fastener configured to secure the cap to the vertebral facet joint;
- wherein the distal surface of the cap comprises a first lattice structure configured to promote bone growth into the cap.
