A method of manufacturing multiple orthopaedic implants includes: producing a strip of material including a composite of a first porous ingrowth material and a second porous ingrowth material; forming a plurality of through-openings in the strip; and cutting a plurality of implant blanks from the strip, each of the implant blanks including at least one of the formed through-openings.

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.

Systems for distracting a facet joint and positioning a permanent implant in the joint are disclosed. The implants serve to retain a distracted position of the facet joint which is achieved with positioning of the leading end of a distraction tool in the facet joint and then distracting or enlarging the joint a desired amount. The permanent implant could be part of the distraction mechanism which can be separated from the delivery tool once the joint has been distracted or an auxiliary implant may be positioned before the distraction mechanism is removed from the distracted joint. The permanent implants can be solid, mechanical devices that may have fixation means thereon to hold them in place or injected fluids such as hydrogels or fluids confined within balloons.

Systems and methods for robotically distracting a disc space are provided for implantation of an intervertebral prosthetic disc. The system includes a 3D modeling system for creating a 3D model of first and second vertebra adjacent the disc space and identifying positions of the first and second vertebrae. A robotic distractor precisely opens the disc space just large enough to receive a selected intervertebral disc. A computing system stores and processes the 3D model and the positions of the first and second vertebrae before and after distraction. A surgeon interface on the computing system allows the surgeon to select an intervertebral disc prosthesis to be implanted and a desired distraction distance or force to be achieved.

A system that includes a cervical plate and an intervertebral cage, the cervical plate having a mounting section that renders the cervical plate mountable to a reference feature located on the front wall of the intervertebral cage, the reference feature being positioned to set a distance between an eyelet of the cervical plate and an edge of the front wall to position the eyelet over a mounting location on a vertebra when the mounting section is mounted to the reference feature.

An interbody tool may include an upper portion with an upper contact surface and a plurality of upper legs; a lower portion with a lower contact surface and a plurality of lower legs, each of the lower legs moveably connected to one of the upper legs; a plurality of gauges, each gauge configured to measure a position of one of the plurality of upper legs relative to a corresponding one of the plurality of lower legs; at least one actuator configured to selectively push the upper portion away from the lower portion; and at least one sensor for measuring a force exerted by the at least one actuator.

The guidance and positioning device may be a system for creating a passage in tissue, positioning fasteners or other implants, and tensioning an elongated fastening member, like a suture, thread, wire, or pin. In some embodiments, the device may allow for the implantation of multiple sutures and fasteners in tissue. A fastener may be positioned at the distal end of a flexible pushrod. The fastener may be connected with the pushrod or may be loosely fitted with the distal end of the pushrod. A suture may be looped through or connected with the fastener such that one, two, or more sections, legs, strands, or portions of the suture extend from the fastener.

An intervertebral spacer may include a fastener channel configured to receive a fastener, a locking member channel, and a locking member. The locking member channel may include an inner wall and one or more inner wall engagement features. The locking member may include an anti-backout member, a collet retainable within the locking member channel, and one or more collet engagement features. The locking member may be rotatable within the locking member channel between an unlocked position and a locked position. The one or more collet engagement features may engage the one or more inner wall engagement features in order to retain the locking member in either the unlocked position or the locked position, such that the anti-backout member may selectively obstruct the fastener channel and prevent the fastener from backing out of the fastener channel.

Stand-alone interbody fusion devices for engagement between adjacent vertebrae. The stand-alone interbody fusion devices may include a spacer and one or more inserts or members coupled to the spacer. The inserts or members may be configured and designed to provide the apertures which are designed to retain bone fasteners, such as screws, and secure the implant to the adjacent vertebrae.

An intervertebral spacing implant, including: a seat having an interior surface and an exterior surface; branches having an anterior end and a posterior end, the anterior end of the branches coupled to the seat and extending in a direction away from the seat, each of the branches having an interior surface and an exterior surface opposite the interior surface, the seat and the branches forming a cage, the exterior surface of the seat and the exterior surface of the branches defining an internal volume of the cage, the cage including fenestrations; a spacer configured to fit within the cage and move in the direction away from the seat and toward the posterior end of the plurality of branches, the spacer and the cage configured such that the branches will move from an unexpanded position to an expanded position when the spacer is urged in the direction away from the seat.
