Abstract: 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.

Abstract: An artificial spinal joint for creating at least a portion of a coupling between a superior vertebra and an inferior vertebra is disclosed. The artificial spinal joint comprises a first arthroplasty half comprising a first articulating joint replacement component for placement in an intervertebral disc space between the superior and inferior vertebrae, a first posterior joint replacement component, and a first bridge component coupled between the first articulating joint replacement component and the first posterior joint replacement component. The artificial spinal joint further comprises a second arthroplasty half comprising a second articulating joint replacement component for placement in an intervertebral disc space between the superior and inferior vertebrae, a second posterior joint replacement component, and a second bridge component coupled between the second articulating joint replacement component and the second posterior joint replacement component.

Abstract: An artificial spinal joint for creating at least a portion of a coupling between a superior vertebra and an inferior vertebra comprises a first joint half comprising a first intervertebral articulating assembly, a first rostral connection assembly, and a first caudal connection assembly. The joint further comprises a second joint half comprising a second intervertebral articulating assembly, a second rostral connection assembly, and a second caudal connection assembly. The joint further comprises a constraint component extending between the first rostral connection assembly and the first caudal connection assembly.
