Devices and methods are provided for treatment of the cervical spine. The devices and methods allow for treatment to be delivered from a lateral or posterior-lateral location of a subject, proximate to the cervical region of the spine. One exemplary embodiment of a spinal implant includes an elongate cage member and a plate member appended to a proximal end of the cage member. The plate member can be oriented in a manner such that it is asymmetric with respect to a long axis of the cage member. In another exemplary embodiment, an implant includes a cage member having a distal end that has an asymmetrical, bulleted shape such that the distal end is biased towards a superior or cranial direction. In a third exemplary embodiment, an implant includes a spinal fixation element and at least two mounting eyelets formed thereon. Exemplary methods related to implanting spinal implants from a lateral or posterior-lateral location are also provided.

Intervertebral spacer assemblies, systems, and methods thereof. A method of insertion include inserting an intervertebral spacer and plate together using an insertion tool and, upon removal of the insertion tool, the intervertebral spacer and plate are no longer considered connected/coupled and act as separate components.

Expandable vertebral body implants, systems, instruments, and methods of assembly and using the implants, systems, and instruments are disclosed. The vertebral body implant includes a body with a first end and a second end, a first rotating member rotatably coupled to the first end, wherein an end includes a plurality of first notches inset into the first rotating member, a second rotating member rotatably coupled to the second end, wherein an end includes a plurality of second notches inset into the second rotating member, a first extension member moveably coupled to the first end, and a second extension member moveably coupled to the second end. The expandable cage system comprises a vertebral body implant and an insertion instrument. Methods for assembling and using the vertebral body implants and instruments are also disclosed.

An intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The implant includes a spacer portion, a plate portion operatively coupled to the spacer portion and one or more blades for securing the implant to the adjacent vertebral bodies. The blades preferably include superior and inferior cylindrical pins for engaging the adjacent vertebral bodies. The implant may be configured to be inserted via a direct lateral trans-psoas approach. Alternatively, the implant may be configured for insertion via an anterior approach.

An implant includes a first plate and a second plate, 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 translate along the first and second plates from a first contracted configuration into a second separated configuration. The implant includes an actuation member coupled to the first wedge member and the second wedge member. The actuating member defines a flange extending toward the first and second plates. The actuation member configured to move the first and second wedge members from the first contracted configuration into the second separated configuration so that the first and second plates separate from each other.

Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants.

A distractor includes a first plate and a second plate. The first plate includes an outer surface having a surface irregularity provided thereon and an inner surface having a protrusion provided thereon. The second plate includes an outer surface having a surface irregularity provided thereon and an inner surface having a recess provided thereon. The protrusion engages with the recess in a ball and socket configuration that permits relative movement of the first and second plates.

A spacer member is provided that is configured to be implanted adjacent an anatomical structure. The spacer member defines a curved bore, a first opening in a side wall of the spacer member and a second opening in one of a top wall and a bottom wall of the spacer member. Each of the first opening and the second opening are in fluid communication with the curved bore. A flexible anchoring member is configured to be inserted through the side opening and through the curved bore of the spacer member such that a distal end portion of the flexible anchoring member extends out of the second opening at an angle relative to the one of the top wall and the bottom wall of the spacer member.

A prosthetic head with a body having the shape of a cup shaped as a hemispherical cap provided with an external surface, an internal surface and a lower edge shaped as a circumference, fixing means to fix the prosthetic head to the cotyle, and a projection abutting from the internal surface of the prosthetic head in such manner to define an annular step, and a truncated-conical portion obtained in the internal surface of the body of the prosthetic head starting from the lower edge of the prosthetic head, the truncated-conical portion of the prosthetic head being suitable for being coupled in conical coupling mode with a truncated conical part of an insert intended to be inserted in the prosthetic head. he projection is shaped as a portion of a spherical cap.

A tool for insertion of an intervertebral insert into an intervertebral space is provided. The tool includes a shaft having a proximal end and a distal end. The distal end of the shaft is configured to be coupled to the intervertebral insert. The tool includes a tapered section located at the distal end of the shaft, the tapered section tapering toward the longitudinal axis of the shaft and away from the proximal end of the shaft. The tool further includes a recess formed in the tapered section, the recess configured to receive the intervertebral insert such that at least a portion of the intervertebral insert is located within the recess when the intervertebral insert is coupled to the shaft.
