See full text

Embodiments of the invention include devices and methods for performing a corpectomy or spinal disc replacement. Devices may include an inferior bearing that is implantable in an inferior vertebral body and a superior bearing that is implantable in a superior vertebral body. The bearings of some embodiments have a support member rotatably coupled between the bearings, and a fixation device may attach the vertebral bodies to the support member with a fastener.
