Related Conditions

Chiari can have Comorbid (Related) conditions. Here are some of them. To learn more about them, click on them to redirect you to a site that describes each.

Here is another video about BI & RO by Dr. Rekate: here

Great diagrams below:

Kaylie's 2 year post-op (1st surgery, done in 2012)  MRI (July 2014)
This is the MRI that dx her with Retroflexed Odontoid Process/Basilar Invagination.
After this MRI, a Flex/Ext MRI was ordered, and performed in Nov. 2014.

Mason's MRI 7/9/12, shows Retroflexed Odontoid Process/Basilar Invagination
He has NO symptoms of the condition. 

Bailey's (Chiari friend we met while in NY) MRI on left side (5/12, was before Fusion surgery to correct BI)
MRI on right side (10/12, was after Fusion surgery.... notice how the brainstem is now straight?)
BIG Difference!!!
Bailey was decompressed due to her Chiari herniation in Dec. '11.
After she was decompressed, she continued to have similar, but different symptoms.
They then did another MRI in May, and realized that because of the small part of her skull
was removed, and that she has EDS it gave her Basilar Invagination the ability to compress more. There
for she under went a fusion for her BI. (basically to help stabilize her brain stem.)
Brenda has a great way of explaining EDS (Ehlers-Danlos Syndrome):
When the collagen does not hold anything in its place the bones basically loose the stability and when the did the decompression it caused more instability. Someone compared the collagen from eds to a rubberband and that when you stretch a rubberband in people with normal collagen the rubberband goes back to its normal shape. With EDS when you stretch it, it stays stretched.
Thank's Bailey & Brenda for letting me share!!!

Thanks Robin, for letting me share!

How Basilar Invagination is measured. It's called the Grabb Oaks Measurement
