Embodiment Construction

[0044] The present disclosure relates generally to systems and methods of spinal surgery, and, more particularly, in some embodiments, to spinal arthroplasty systems and methods for posterior implantation. To facilitate an understanding of the principles of the invention, reference will now be made to the embodiments or examples illustrated in the drawings and specific language will be used to describe the same. It should be understood, however, that no limitation of the scope of the invention is intended. Any alterations and further modifications in the described embodiments, and any further applications of the inventive principles described herein are contemplated as would normally occur to one of ordinary skill in the art to which this disclosure pertains.

[0045] first reference figure 1 , shows a sagittal view of the spine 10 illustrating the series of vertebrae V1, V2, V3, V4 separated by native intervertebral discs D1, D2, D3, respectively. Although this illustration...

Abstract

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.

Description

Background technique [0001] Sometimes, the cause of a patient's back pain may not be clear. Disease, degeneration or injury of the intervertebral disc or associated articular surfaces are among the possible causes of pain. Disc arthroplasty is one of the ways to treat the joints of the spine to reduce pain while maintaining motion within the joint. Optional treatments focus on the articular surfaces, which can be removed and replaced with a prosthetic device. Currently, there are few options for treating the entire spine joint, including the disc and associated articular surfaces. Due to their size, existing disc arthroplasty instruments typically involve an anterior surgical approach. In addition to being highly invasive, the anterior surgical approach does not allow the surgeon to easily access and repair or replace afflicted articular surfaces. Accordingly, there is a need for a motion preserving joint replacement system that treats the total spinal joint by replacing a...
