Abstract: Provided herein are an anchor and interbody for interbody fusion, including an interbody for insertion between human vertebrae, including an interbody cage including a plurality of anchor receptacles, each anchor receptacle configured to receive an anchor to secure the interbody to a vertebra; and the anchor, including a head configured to engage an anchor receptacle; a curved partial-tubular shank with a convex curve, connected to or integral with the head at a distal end of the head, and extending from the head; a tapered tip portion extending from a distal end of the curved partial-tubular shank; one or more rails integral with or connected to an outside surface of the anchor, extending from a proximal end of head and along the curved partial-tubular shank to a proximal end of the tapered tip portion; and a feature formed from two flat surfaces on an outside of the anchor and a rail.

Abstract: Provided herein is a spinal interbody device including an interbody; and a movable backout prevention mechanism disposed at least partially within the interbody, comprising a body and one or more lobes integral with the body, wherein each of the one or more lobes is configured to be moved between an unlocked position for insertion of a fixation member and a locked position for preventing backout of the fixation member.

Abstract: Provided herein are anchors and interbodies for interbody fusion, comprising an interbody for insertion between vertebrae of a human spine, comprising an interbody cage comprising a plurality of anchor receptacles, each anchor receptacle configured to receive an anchor to secure the interbody to a vertebra; and the anchor, comprising a head configured to engage one of the plurality of anchor receptacles; a curved partial-tubular shank connected to or integral with the head at a proximal end of the curved partial-tubular shank, extending from the head, and comprising a plurality of concentric grooves on an exterior surface of the curved partial-tubular shank; and a straight tapered tip portion at a distal end of the curved partial-tubular shank and extending from the curved partial-tubular shank.

Abstract: A spinal implant comprising a major branched lattice formed in at least a portion of a middle portion of the spinal implant; and a minor branched lattice formed throughout the major branched lattice.

Abstract: Coupling assemblies and systems and methods are provided with an anchor member movably coupled with a receiver member extending along a receiver axis. A seat member is movable in the receiver member to assume any one of a plurality of orientations corresponding to an orientation of a connecting element extending through the receiver member transversely to the receiver axis.
