Abstract
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.
