An interbody spacer for the spine comprises an anchor assembly removably connectable to a cage. The anchor assembly includes at least two non-screw bone anchors. With insertion of the anchor assembly into the cage, at least one anchor slides against a ramp from an undeployed configuration to rotate up with respect to the plate and out of an upper exit opening of the cage for anchoring into an upper vertebral body and a second anchor slides against a ramp to rotate down with respect to the plate and out of a lower exit opening of the cage for anchoring into a lower vertebral body. The anchor assembly locks with respect to the cage by way of deflectable locking tabs.

The present disclosure pertains to ionic polymer compositions, including semi- and fully interpenetrating polymer networks, methods of making such ionic polymer compositions, articles made from such ionic polymer compositions, and methods of making such articles and packaging for such articles.

A prosthetic intervertebral spacer includes a body having a front end, a rear end, an anterior side, a posterior side, a top surface, and a bottom surface, and an arcuate interface extending away from the body and being connected to the rear end and the posterior side of the body. A method of inserting and positioning the spacer includes engaging a tool to the interface, inserting the spacer at least partially into the intervertebral disc space by moving the tool along an insertion direction, and allowing the spacer to rotate with respect to the insertion direction within the intervertebral disc space while continuing to move the tool along the insertion direction.

An implant is provided for performing spinal fusion. The implant includes an implant body having a leading side and a trailing side at opposing ends along a longitudinal axis. Between the leading side and trailing side are an upper surface, a lower surface, an anterior side, and a posterior side. At least one keel structure is provided extending from the implant body for penetration into an adjacent vertebral body. A trial sizer and keel cutter may be utilized to form keel channels within the vertebral body to receive the keel structure.

An implant is insertable in the joint space to separate bones of the joint. The implant has two endplates each configured to engage a separate articulating bone of the joint, and a threaded member positioned between the two endplates and configured to increase the space between the two endplates when the threaded member is rotated. A rotatable gear is engaged with the threaded member, and is engageable with a rotating gear of a connected implantation tool, so that rotation of the gear on the tool causes rotation of the threaded member and expansion of the implant to separate the bones. Connector portions on the tool and the implant may be rotated together to securely engage the implant and the tool so that the gears of the tool and the implant can be rotated using an actuator outside of the body, when the implant is inside the body.

Provided is a variable lordotic expanding implant with a centralized graft deployment delivery channel (tube) with (or without) an expanding footprint mesh component which is deployed by graft material injection.

A spinal implant includes a body having opposite first and second end walls and opposite first and second side walls. The side walls each extend from the first end wall to the second end wall. A first cap is coupled to top ends of the walls. A second cap is coupled to bottom ends of the walls. The implant includes an opening extending through the caps such that the first cap defines a first ledge extending from the walls to the opening and the second cap defines a second ledge extending from the walls to the opening. Systems and methods of use are disclosed.

A surgical instrument comprises a first portion defining a cavity configured for disposal of a first implant support member. A second portion defines at least one passageway aligned with the cavity and including a guide engageable with a second implant support member to orient the second implant support member with the at least one passageway such that the second implant support member is connectable with the first implant support member. Systems, spinal constructs, spinal implants and methods are disclosed.

A stand-alone ALIF implant that comprises a cage and a rotatable plate attached to an anterior portion of the cage by a fastener mechanism. The plate may also be integrally formed with the cage, and both are typically manufactured using additive manufacturing techniques. Support material may be added during the additive manufacturing process to lend support to the implant, and may be positioned around the fastener mechanism during manufacturing of the implant. Once formed, the support material may be dissolved away, thereby allowing the plate to rotate independently from the cage, but still remain movably attached via the fastener mechanism. The cage may further comprise webbing thereon to promote bone growth.

Disclosed are system and methods that use at least one non-threaded anchor and an implant with at least one aperture to join boney structures, where the interaction of the head of the anchor with the implant aperture causes the anchor to move transversely with respect to an initial trajectory. This movement causes compression or distraction of the boney structures which are coupled to the anchors.
