Talk:Craniocervical instability

New pages needed or glossary entry[edit source | reply | new]

There's many links to pages that could be created being used, when these pages have little to do with ME/CFS and aren't likely to get much content (assuming that they ever get created). It would be better to add these to the Glossary page, which creates an automatic lookup on any pages that use the word or phrase.

I've removed some links to non-existent pages from this page and would appreciate these either being added to the glossary or defined here, ready to add. Please add any others you think would be useful. Many will have a clear definition in the Merrian-Webster Medical Dictionary.

  • Apnea
  • cervical
  • congenital
  • craniocervical junction, or CCJ
  • Endothelial
  • ligament
  • ligamentous
  • ligamentous laxity
  • myocyte
  • myositis
  • odontoid
  • flexion
  • proprioception
  • neoplasm
  • nystagmus
  • senescent
  • spinal instability
  • supine
  • torticollis

Glossary terms should be singular and aliases like the plural spelling or capitalization can be added in the definition ~Njt (talk) 12:44, October 28, 2021 (UTC)

Translational BAI is wrong based on n=400 study -- Eldask (talk) 08:16, August 19, 2019 (EDT) -- Eldask (talk) 08:16, August 19, 2019 (EDT)[edit source | reply | new]

I have growing concern regarding the work of the big 4 on CCI.

Henderson's work is being cited left and right with no fact checking, which is extremely dangerous considering the seriousness and impact of craniocervical arthrodesis.

This page states a translational BAI bigger than 2 or 4 as pathological, yet, a study referenced by Henderson (https://doi.org/10.2214/ajr.162.4.8141012) states "The excursion of the basion in flexion and extension ranged from 0 to 10 mm, but did not exceed the 12-mm limit of normal" on n=392 healthy subjects.

Though translational BAI below 10mm may in certain cases indeed be pathological, I strongly recommend amending that metric to reflect that objective study and not blurring the picture with metrics which are neither particularly sensitive or specific.


Thanks for your commentUser:Eldask. I share your concerns and think it would be best just to leave out the table about specific measurements and cutoffs. These rely almost solely on the work of Henderson and Bolognese and I suspect that those writing the info on MEpedia don't have the necessary medical background to know how to interpret them. I don't think this kind of detail is helpful as medical decisions about whether these measurements indicate relevant pathology should be considered by experts. Including them on the MEpedia page is contrary to that view - I think it will mostly cause confusion. It also promotes the view of Bolognese who is controversial and has been sued multiple times for performing unnecesary surgery.

Ref 43 & 13 appear to be the same - August 8/25/2019[edit source | reply | new]

References 43 and 13 appear to be the same paper. There are linked on Translational BAI measurement in the ref section of the measurement table -- Luke S.

Use Craniocervical instability term more for SEO? - August 8/28/2019[edit source | reply | new]

I see the term Craniocervical instability is only used in the heading, should we use the full term instead of CCI to improve search engine ranking? -- Luke S.
