Described herein are devices and methods for fusion of adjacent vertebral bones using distractor platforms for exposure and resection of at least a portion of a facet joint, such as in performance of a TLiF procedure. In one embodiment, the distractor platform contains at least a first receptacle and/or extension adapted to couple to the implanted screw/bone marker, and the method includes advancing a threaded segment of a bone fastener assembly into the identified first pedicle of the first vertebral bone, the bone fastener assembly further comprises a second segment adapted to couple with a distraction platform, which is adapted to concurrently attach onto at least one tissue retention blade, and retain the tissue retention blade in the displaced position. Stabilization of a spinal segment is also provided by advancing a substantially concave orthopedic implant through an opening made in a posterior aspect of a disc space.

In some embodiments, the present disclosure relates to a system that includes an insertion tool and a drill guide. The insertion tool includes a body with a distal portion and a distal end. The body has a first engagement feature extending longitudinally along the distal portion and two arms extending longitudinally from the distal end of the body. The drill guide includes two bores and an open faced channel therebetween. The open faced channel includes a second engagement feature slidably engageable with the first engagement feature on the body of the insertion tool. The two bores are adapted for the disposal of a fastener driver tool therethrough.

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.

A prosthetic system for implantation between upper and lower vertebrae having an upper joint component and a lower joint component. The joint is adapted for implantation within a disc space between the upper and lower vertebrae, allowing the upper and lower vertebrae to move relative to one another. The system further includes a bridge component extending posteriorly from the lower joint component and from the disc space, with the bridge component having a lower contact surface configured for engaging a resected bone surface of a pedicle of the lower vertebrae. The distal end of the bridge component comprises a connection component adapted to receive a fastener.

An intervertebral scaffolding system is provided having a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state, the laterovertically-expanding frame having a stabilizer that slidably engages with the distal region of the laterovertically-expanding frame and is configured for retaining the laterovertically-expanding frame from a lateral movement that exceeds the expanded state. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

An intervertebral implant for implantation in an intervertebral space between vertebrae. The implant includes a body having a front end, a rear end and a pair of spaced apart first and second side walls extending between the front and rear ends. The front and rear ends extend in a transverse direction and a central axis of the body extends from the rear end to the front end. The rear end defines a first fastener hole having a first central axis and a second fastener hole having a second central axis. The first and second central axes extend parallel to one another at an acute angle relative to the body central axis in the transverse direction.

An example expandable interbody device can include a structural body having an upper endplate and a lower endplate, where the endplates are shaped to nest tightly in a closed position. The device can include at least one wedge block and at least one linkage block arranged between the upper and lower endplates of the structural body. The device can include a drive screw threaded through the at least one wedge block and the at least one linkage block. The drive screw can be configured to rotate and drive the at least one wedge block to expand the upper and lower endplates of the structural body from the closed position to an intermediate position. Additionally, the drive screw can be further configured to rotate and drive the at least one linkage block to expand the upper and lower endplates of the structural body from the intermediate position to an open position.

A system for use during surgical procedures. The system includes an implant and a tool. The implant combines a modular adjustable cage and a shim that locks the cage into position, after the cage has been adjusted to its final position and at its final height, in situ. The tool combines an expander and an inserter. A related method of using the system is also provided.

Disclosed herein are systems and methods for intervertebral body fusion that provide more robust support within the disc space. Intervertebral body fusion devices can have a unitary monolithic body including a plurality of body segments interconnected with each other by flexure members. Devices be configured to be inserted through an opening in a compressed configuration and then expanded within the disc space to an expanded configuration. In the expanded configuration, devices can have a greater mediolateral or transverse to the disc space footprint. This wider footprint provides greater support for the vertebrae relative to the size of the opening through which the device is inserted.

An interbody fusion device includes a base member, a top member, and an expansion mechanism for moving the top member relative to the base member. The expansion mechanism may include a connector drive rod assembly, a gear, a threaded rod, and a support means. The gear ring is coupled to the threaded rod and is rotatable. The expansion mechanism may also include at least one load head coupled to the threaded rod. An alternative interbody fusion device is also disclosed and includes a bottom member, a superior member, and an expansion mechanism for moving the superior member relative to the base member, wherein the expansion mechanism comprises at least one expansion assembly for moving an end of the superior member relative to the bottom member.
