Cervical corpectomy is an operation to remove a portion of the vertebra and adjacent intervertebral discs for decompression of the cervical spinal cord and spinal nerves.
The vertebral body bone that is removed is typically saved and is the graft used to place into the cage device. The biomechanical cage or spacer is typically made of metal alloy, carbon fiber or polymer. The bone graft serves as a bridge between the two vertebrae to create a spinal fusion. A metal alloy plate and screws are typically but not always used to provide stability to the cage device.
