An artificial spinal joint for creating at least a portion of a coupling between a superior vertebra and an inferior vertebra comprises an articulating joint replacement assembly. The articulating joint replacement assembly comprises an anterior joint replacement component extending into an intervertebral disc space between the superior and inferior vertebrae, a first posterior joint replacement component, and a first bridge component coupled between the anterior joint replacement component and the first posterior joint replacement component. The artificial spinal joint further comprises a support joint replacement assembly. The support joint replacement assembly comprises an anterior support component extending into an intervertebral disc space between the superior and inferior vertebrae, a second posterior joint replacement component, and a second bridge component coupled between the anterior support component and the second posterior joint replacement component. The anterior support component is engaged with the articulating joint replacement component.

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. The first articulating joint replacement component is engaged with the second articulating joint replacement component.
摘要:
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.
摘要:
An artificial spinal joint for creating at least a portion of a coupling between a superior vertebra and an inferior vertebra comprises an inferior arthroplasty half. The inferior arthroplasty half comprises an inferior articulating component for placement in an intervertebral disc space between the superior and inferior vertebrae, a first posterior arm, and a first bridge component coupled between the inferior articulating component and the first posterior arm. The artificial spinal joint further includes a superior arthroplasty half. The superior arthroplasty half comprises a superior articulating component for placement in an intervertebral disc space between the superior and inferior vertebrae, a second posterior am, and a second bridge component coupled between the superior articulating component and the second posterior arm. The first posterior arm and the second posterior arm cross an anterior-posterior axis defined centrally through and extending from the intervertebral disc space.
摘要:
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.
摘要:
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.
摘要:
An artificial vertebral joint is interposed between a superior vertebra and an inferior vertebra. The artificial vertebral joint comprises a rostral joint component having a first surface adapted for engagement with an endplate of the superior vertebra, a first anterior articulation surface, and a support tab adapted for extending from the first surface and for engaging a portion of the endplate. The portion of the endplate extends from the first surface to a posterior edge of the endplate. The joint further comprises a caudal joint component having a second surface adapted for engagement with an endplate of the inferior vertebra and a spacer component adapted for interposition between the rostral joint component and the caudal joint component.

The present disclosure relates, according to some embodiments, to devices, systems, and/or methods for delivery (e.g., controlled delivery) of a pharmaceutical to a subject's spine. For example, the disclosure relates to implants that provide both a mechanical function and a pharmacological function. According to some embodiments, a spinal implant may comprise a rigid spinal implant body having one or more recesses, one or more layers in each of the one or more recesses, each of the one or more layers comprising a biocompatible material and a pharmaceutically effective amount of a pharmaceutical compound; and at least one biocompatible cap in each of the one or more recesses. An implant may further comprise biocompatible barriers interspersed between the layers.
