摘要： The various embodiments described herein provide lateral mass and facet fixation implants, which may be inserted and applied via a posterior approach, using minimally invasive or less invasive techniques. The embodiments described below generally include an intrafacet implant (or “facet implant”) and a lateral mass fixation member attached to or attachable to the facet implant. The lateral mass fixation member can include one or more tabs extending from a middle portion and configured to secure the lateral mass fixation member to lateral masses of adjacent vertebrae. The tabs may be flexible, semi-rigid, or rigid, and may be collapsible to facilitate insertion of the device. Methods for delivering the lateral mass and facet fixation implants are also described.

摘要： A spinal implant for implantation within a spinal facet joint is provided. The spinal implant may include a main body including opposing top and bottom surfaces, opposing front or distal and rear or proximal surfaces, and opposing side surfaces. At least one retaining feature may be associated with at least one surface of the main body to frictionally engage the implant within the spinal facet joint. At least one securement feature may be associated with at least one surface of the main body to selectively secure the implant within the spinal facet joint.

摘要： Implementations described and claimed herein provide a spinal facet cage implant for implantation in a spinal facet joint. In one implementation, the implant includes a distal leading end, a proximal trailing end, a first face, and a second face. The distal leading end has a distal surface generally opposite a proximal surface of the proximal trailing end. The first face has a first surface that is generally parallel with a second surface of the second face. The first and second faces extend between the distal leading end and the proximal trailing end. The first and second surfaces having one or more textured features adapted to provide friction with the spinal facet joint. One or more windows are defined in the first and/or second surfaces, and one or more side windows are defined in the first and/or second side surfaces.
