Expandable Intervertebral Prosthesis Device for Posterior Implantation and Related Method Thereof

摘要

A method and device for the insertion of a vertebral cage that may be done through a posterior approach that is minimally traumatic and does not require retraction of the spinal cord, dural sac or spinal nerves. The insertion of the cage may therefore be parallel to the spinal cord and the cage will be rotated ninety degrees (or as desired or required) in the vertebral body defect or as applicable to achieve its proper positioning before expansion.
