Abstract
BACKGROUND: Screw migration following anterior cervical discectomy and fusion is a very rare complication and it is often related to device failure. Even more exceptional is the extrusion of an intervertebral graft. CASE PRESENTATION: We report the second case of migration and extrusion through the oral cavity of a cervical vertebral body replacement device (expandable cylinder) in a patient that had undergone cervical corpectomy due to a vertebral chordoma. CONCLUSION: The antecedent of radiation therapy as well as progressive tumor re-growth may have favored the development of this complication. A literature review is added.
