In anterior cervical surgery, bone grafting is not required when an artificial cervical disc is placed. When the degeneration is more severe and cervical mobility cannot be preserved and an intervertebral fusion or artificial titanium cage is chosen for spinal stability reconstruction, bone grafting is required. Because the internal fixation currently used does not have the ability to grow with the bone, bone grafting is required. The internal fixation provides stability early on, and the ultimate goal is to grow the bone graft with the vertebral body above and below the operated segment, known as fusion. Perhaps in the future, when technology has developed, there will be no need for bone grafting, which can also be expected.
