Abstract: Provided is an intervertebral implant to be implanted within an intervertebral space between endplates of adjacent vertebra during use. The implant includes an upper member having an inferior surface including an upper guide track and a superior surface to contact an endplate of an upper one of the adjacent vertebra during use, a lower member having a superior surface including a lower guide track and an inferior surface to contact an endplate of a lower one of the adjacent vertebra during use, and an insert having a superior surface including an upper guide rail to engage the upper guide track during use and an inferior surface including a lower guide rail to engage the lower guide track during use. Engagement of the upper and lower guide rails with the upper and lower guide tracks, respectively, guides insertion of the insert between the upper and lower members during use, and insertion of the insert between the upper and lower members facilitates expansion of the intervertebral implant.

Abstract: In some embodiments, an intervertebral implant may include a body including a superior and an inferior surface. The implant may include a first channel extending from an anterior end towards the posterior end of the body. The implant may include a first anchor channel The implant may include a first guide member positionable in the first channel The implant may include a first anchor. When the first guide member moves from a first position to a second position the first anchor may be conveyed through the first anchor channel and couple the body to an adjacent vertebra.

Abstract: A system includes a patella trial comprising a baseplate and an articular surface member configured to move along at least one of a medial-lateral axis or a superior-inferior axis of the baseplate; and an implant comprising a posterior articular surface and an anterior surface, wherein the anterior surface has a medial/lateral width with a midpoint, wherein the posterior articular surface has a posterior-most point, wherein an imaginary line extending through the posterior-most point is parallel to an imaginary line extending through the midpoint, and wherein a distance (I) is defined by measuring a length between the imaginary line extending through the posterior-most point and the imaginary line extending through the midpoint; wherein the implant is selected from a set of implants each having a different I, and wherein the chosen implant is selected based on an offset of the articular surface member relative to the baseplate on the patella trial.
