Abstract
An intrafacet implant includes a body having a shank, one or more threads extending around the shank, a plurality of windows positioned along the shank, and one or more passages extending through the shank. Each passage extends between two windows.
Claims20
An intrafacet implant comprising:
- a body extending from a proximal end to a distal end, the body comprising a solid, non-canulated shank comprising a central longitudinal axis extending from the proximal end to the distal end;
- one or more threads extending around the shank, at least one of the one or more threads completing a full rotation around the proximal end of the shank;
- a plurality of windows positioned along the shank, each of the plurality of windows comprising a first dimension extending in a direction parallel with the central longitudinal axis of the body, wherein the first dimension is greater than a distance between two adjacent threads of the one or more threads;
- and
- one or more passages extending through the central longitudinal axis of the shank, each passage extending between two windows of the plurality of windows, wherein the one or more passages comprise a first passage and a second passage, wherein the first passage is circumferentially offset from the second passage about the central longitudinal axis of the body so that at least one of the plurality of windows is positioned to align with a superior vertebral body of a facet joint and at least one of the plurality of windows is positioned to align with an inferior vertebral body of the facet joint when the intrafacet implant is implanted within the facet joint;
- wherein the body comprises a closed proximal portion positioned proximally above the one or more passages and a closed distal portion positioned distally below the one or more passages.

A method for performing a spinal fusion procedure, comprising:
- making an incision;
- advancing an intrafacet implant to a facet joint through the incision, the intrafacet implant comprising:
- a body extending from a proximal end to a distal end, the body comprising a solid, non-canulated shank comprising a central longitudinal axis extending from the proximal end to the distal end;
- one or more threads extending around the shank, at least one of the one or more threads completing a full rotation around the proximal end of the shank;
- a plurality of windows positioned along the shank, each of the plurality of windows comprising a first dimension extending in a direction parallel with the central longitudinal axis of the body, wherein the first dimension is greater than a distance between two adjacent threads of the one or more threads;
- one or more passages extending through the central longitudinal axis of the shank, each passage extending between two windows of the plurality of windows, wherein the one or more passages comprise a first passage and a second passage, wherein the first passage is circumferentially offset from the second passage about the longitudinal axis of the body so that at least one of the plurality of windows is positioned to align with a superior vertebral body of a facet joint and at least one of the plurality of windows is positioned to align with an inferior vertebral body of the facet joint when the intrafacet implant is implanted within the facet joint;
- wherein the body comprises a closed proximal portion positioned proximally above the one or more passages and a closed distal portion positioned distally below the one or more passages;
- and
- implanting the implant within the facet joint.
