the buckling of the LF WAS not exist before (8.2020 small evidence) but in 2021 very see and 22 and 23 .
I share a video of a section of MRI 16 via 20/21/22/23
2016 show degenerative disc in c2-4 and thin disc c4-5 .(what leads future to stenosis (ligament buckling )
also I see the facet arthritis (between inferior to superior articular pillars on the last MRI )
take a look to this.
