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.

Embodiments herein are generally directed to spinal implants, systems, apparatuses, and components thereof that can be used in spinal fusion and/or stabilization procedures, as well as methods of installation. The spinal implants may include an intervertebral spacer and a plate member.

Spinal spacing implants, spinal spacer assembly, expander and insertion instruments, kits and methods of assembly and use are disclosed. The spinal implant replacement instrument kit including a distraction instrument, a spacer inserter, and a spinal implant. A distraction instrument includes a first inserter member, a second inserter member, a first arm coupled to the first inserter member, a second arm coupled to the second inserter member, a distraction system coupled to the first arm and second arm, a first handle coupled to the first arm and the distraction system, and a second handle coupled to the second arm and the distraction system. Spinal spacing implants, spinal spacer assemblies, and methods of assembling and using the implants assemblies, and instruments are also disclosed.

A method of joining adjacent bone includes providing a medical device having a first implant portion, a second implant portion attached to the first implant portion, and a driver assembly having an instrument adapted to form an opening in bone. The driver assembly is integrally connected to and removably attached to the second implant portion at a connection, distal from the first implant portion. The driver assembly further has a wire driver extending therefrom, distal from the first implant portion. The method further includes inserting the wire driver into a wire driver tool; placing the first implant portion against a first bone structure; inserting the first implant portion into the first bone structure; removing the second implant portion from the driver assembly; using the driver assembly to form an opening in a second bone structure, adjacent to the first bone structure; and inserting the second implant portion into the opening.

A device and methods for intervertebral spinal fusion of adjacent intervertebral bodies. An intervertebral spacer is positioned within a narrow disc space between adjacent intervertebral bodies of a patient. The spacer is arranged with upper and lower guides. The guides are adapted to simultaneously guide the deployment of upper and lower anchors of an anchoring device into their respective intervertebral bodies. The spacer is also adapted to lock the upper and lower anchors to the spacer in the deployed position.

The present invention involves a system and methods for assembling and implanting a vertebral body implant. The vertebral body implant includes, but is not necessarily limited to, an expandable core body and endplates that can be attached at both ends. End plates of various shapes, sizes and angles are attachable to the expandable core in a plurality of positions so that a suitable vertebral body implant can be implanted between vertebrae from an anterior, anterior-lateral, lateral, posterior or posterior-lateral approach.

Exemplary embodiments of apparatuses and methods of an expandable fusion device are provided. In one embodiment, an intervertebral implant can be provided, having a first endplate having an upper surface and a lower surface, a second endplate having an upper surface and a lower surface. A first side wall extends from the first endplate and a second side wall extends from the second endplate and are configured to engage one another to provide a selective variable height between the first endplate and the second endplate. The first side wall and the second side wall form a substantially hollow portion substantially enclosed by the first endplate, second endplate and the side walls. The substantially hollow portion is configured to receive bone growth inducing material.

Devices and methods for intervertebral spinal fusion of adjacent intervertebral bodies are provided. An intervertebral spacer is positioned within a narrow disc space between adjacent intervertebral bodies of a patient. The spacer is arranged with upper and lower guides. The guides are adapted to simultaneously guide the deployment of upper and lower anchors of an anchoring device into their respective intervertebral bodies. The spacer is also adapted to lock the upper and lower anchors to the spacer in the deployed position.

An expandable intervertebral implant includes a first endplate and a endplate, a first wedge member and a second wedge member spaced from the first wedge member that couple the first and second plates together. The first and second wedge members configured to move between a first collapsed position and a second expansion position. The implant includes an actuation member coupled to the first wedge member and the second wedge member. The first and second wedge members can be coupled to the upper and lower endplates at guide members that are asymmetric. An instrument can be coupled to the implant so as to provide a force to the actuation member that causes the wedge members to move between the collapsed position and the expansion position. The instrument can include a drive shaft and a toggle member that is configured to move the drive shaft between a first position whereby the drive shaft is configured to drive an attachment pin into the implant, and a second position whereby the drive shaft is aligned to drive the actuation member to rotate.

An osteotome having a shaft assembly that includes a guide extending in a longitudinal direction of the shaft assembly, and a blade adjacent the guide and extending in the longitudinal direction of the shaft assembly.
