Atlantoaxial instability secondary to os odontoideum is a possible complication in Down syndrome. Common surgical treatment strategies include C1-2 fusion or occipitocervical fusion. The primary advantage of C1-2 fusion is motion preservation at the C0C1 joint, however, various anatomic abnormalities can preclude safe pedicle screw placement at C2. 5 mm and smaller C2 pedicles create a challenge in one-third of os odontoideum cases, thus appropriate utilities or alternative surgical strategies must be considered. Here we detail the utility of a real-time intraoperative navigation setup that allows for multiple in situ re-registrations for precise localization. We present a patient with Down syndrome with progressive myelopathy secondary to atlantoaxial insta... view more»
