A prosthetic system for implantation between upper and lower vertebrae comprises an upper joint component. The upper joint component comprises an upper contact surface and an upper articulation surface. The system further includes a lower joint component. The lower joint component comprises a lower contact surface and a lower articulation surface configured to movably engage the upper articulation surface to form an articulating joint. The articulating 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 one of either the upper or lower joint components and from the disc space. The bridge component has a distal end opposite the one of the either upper or lower joint components. The distal end of the bridge component comprises a connection component adapted to receive a fastener.

Posterior total joint replacement

Intervertebral prosthetic systems, devices, and associated methods are provided. The present disclosure provides intervertebral prosthetic devices that include lateral plates to engage the lateral walls of the vertebral bodies for stability and include a compliant central component, fusion-cage central component, or any other suitable type of motion-preserving or fusion component positioned between the lateral plates. In some instances, the lateral plates and the central component are connected by an elongated member that extends across the disc space. The designs of the present disclosure allow insertion through a unilateral approach yet still have engagement on both sides of the vertebral body to provide stability and reduce the risk of subsidence.

Intervertebral prosthetic systems, devices, and associated methods

Intervertebral prosthetic systems, devices, and associated methods are provided. The present disclosure provides top and bottom endplates that engage the lateral walls of the vertebral bodies for stability and incorporate a compliant core, ball-and-socket core, fusion-cage core, or any other suitable type of motion-preserving or fusion cores. The endplate designs allow insertion through a unilateral approach yet still have engagement on both sides of the vertebral body to provide stability and reduce the risk of subsidence. In some instances, saddle style endplates are inserted and then rotated to engage the lateral walls of the vertebral bodies. In other instances, hinged style endplates are inserted in a first orientation and then at least one end portion is pivoted to a second orientation so that the endplates engage the lateral walls of the vertebral bodies.

An artificial spinal joint, for creating at least a portion of a coupling between a superior vertebra and an inferior vertebra, comprises an anterior joint replacement component sized to extend into an intervertebral disc space between the superior and inferior vertebrae. The anterior joint replacement component includes a left anterior member separated and spaced apart from a right anterior member. The artificial spinal joint further comprises a bridge component coupled at a first end to the anterior joint replacement and sized to extend posteriorly outside the intervertebral disc space. The bridge component includes a left bridge member separated and spaced apart from a right bridge member. The artificial spinal joint further comprises a posterior joint replacement component coupled to a second end of the bridge component. The posterior joint replacement component includes a left posterior member separated and spaced apart from a right posterior member.

Spinal device and method

Embodiments of the invention include expandable, implantable devices and methods. Devices expand linearly to provide secure fixation between or among anatomical structures. In some embodiments, an implant replaces one or more vertebral bodies of the spine.

Expandable implant, instrument, and method

An artificial vertebral joint for interposition between a superior vertebra and an inferior vertebra comprises a pair of bilateral joint subcomponents. Each joint subcomponent includes a superior component including a superior vertebra engaging surface and an inferior component including an inferior vertebra engaging surface. Each joint subcomponent further includes a spacer extending between the superior component and the inferior component. The spacer includes a first modulus of elasticity and a second modulus of elasticity. The first modulus transitions to the second modulus with a gradient change.

Total joint replacement

The present application is directed to devices and methods for cutting a spinal implant. In one embodiment, the device includes a handle and a head. The handle is sized to receive a predetermined length of the implant. A head is rotatably attached to the handle and includes a blade. After the implant is inserted into the handle, the head is rotated causing the blade to move around the implant and cut an excessive length from the predetermined length.

Devices and methods for cutting a vertebral implant

A prosthetic device for posterior placement in an intervertebral space defined between an upper vertebrae and a lower vertebrae may include an upper articular portion configured to be at least partially disposed in the intervertebral space and a lower articular portion configured to be at least partially disposed in the intervertebral space below the upper articular portion, the upper and lower articular portions being configured to provide articulating motion to the upper and lower vertebrae. The upper and lower articular portions each may include a posterior section configured to be disposed in a location posterior of the intervertebral space. The posterior section of one of the upper and lower articular portions may include a post, and the posterior section of the other of the upper and lower articular portions may include a receiving portion configured to interact with the post during articulation.

Posterior joint replacement device

An artificial spinal joint creates at least a portion of a coupling between a superior vertebra and an inferior vertebra. The artificial spinal joint comprises an anterior joint replacement component extending into an intervertebral disc space between the superior and inferior vertebrae. The artificial spinal joint further comprises a bridge component coupled to the anterior joint replacement and extending posteriorly from the anterior joint replacement beyond the intervertebral disc space and a posterior joint replacement component coupled to the bridge, wherein the posterior joint replacement component includes a posterior protrusion engaged with a posterior socket.

Dual articulating spinal device and method

An end device attached to an implant and methods of use. The end device comprises a base having a receiving area, an opening, and at least one gate that is selectively positionable between open and closed orientations. The implant is sized to fit through the opening and into the receiving area when the gate is in the open orientation. Once inserted, the gate is sized to extend across at least a section of the opening and prevent the implant from escaping.

End device for a vertebral implant

The present application is directed to spacing devices that attach directly or indirectly to vertebral implants. The spacing device may include a first side that faces the implant, and an angled second side that faces towards a vertebral member. The angled second side matches the shape of the vertebral member. The devices may further include apertures that receive spikes that extend outward from the implant. The second side may also include spikes that bite into and maintain the position of the device against the vertebral member. In one method of use, the spacing device may be rotated relative to the implant for the angled second side to match the vertebral member. The apertures are then placed over the spikes that extend outward from the implant to connect the spacing device to the implant.
