“…15,16 Our earlier articles introduced the terms 'external' syringomyelia and 'external' syringobulbia and discussed similarities in function with syringomyelia and syringobulbia. 17 Retroodontoid 'pseudotumor' was also identified to be secondary alteration related to atlantoaxial instability and mimicked osteophytes in the subaxial spine. 18 Our observations suggest that all the secondary musculoskeletal or neural alterations when present in isolation or in cohort are indicators of presence of atlantoaxial instability.…”

The atlantoaxial joint is the most mobile joint of the spine and is most liable to develop instability. Atlantoaxial instability can be identified on observation of facetal alignment on lateral profile imaging, telltale clinical and radiological evidence and by direct observation of instability by manual manipulation of bones during surgery. Central or axial atlantoaxial instability is when there is no abnormal increase in atlantodental interval on dynamic imaging and there is no dural or neural compression by the odontoid process. Understanding and appropriately treating central or axial atlantoaxial instability can have clinical implications.

“…Excessive amount of CSF is seen inside the neural structures (syringomyelia, syringobulbia) and outside the neural structures (external syringomyelia and external syringobulbia). [ 11 ] This CSF cavitation provides a “solid” and noncompressible buffer that protects the neural structures. It is indeed astonishing to see how nature gets rid of more dispensable neural pathways and protects the more important ones in an attempt to reduce the girth of the craniocervical spinal cord while retaining important motor and sensory functions.…”
