This was the patient that we demonstrated earlier with the
0:04
Jefferson fracture of C1, a burst fracture of C1.
0:09
One thing that we didn't point out in the same case
0:11
was that it did look like there was some endplate,
0:14
depression and irregularity along the
0:17
superior endplate of the T1
0:18
vertebra. We weren't really sure whether
0:21
this was just an elderly patient.
0:23
You can see that there's quite a bit
0:24
of DJD with degenerative change,
0:27
but we were concerned about the presence of the superior
0:31
endplate, what looked like fragmentation at T1.
0:35
So let's look at the MRI scan on this individual.
0:39
This is the MRI scan on the patient
0:42
that had the Jefferson fracture.
0:44
And we had previously looked at the high signal intensity at
0:48
the occipital condyle C1 level and the C1-C2 level.
0:54
What we didn't pay attention to was the signal
0:56
intensity of the superior endplates of
1:00
T1, and in point in fact, T2.
1:02
This bright signal intensity in these superior
1:04
endplates likely represents bone edema,
1:07
and in this particular individual, was seen to
1:09
correspond with a fracture of that superior endplate.
1:13
So not just at the C1 level, but also at the T1 level.
1:17
And what we didn't appreciate on the CT scan,
1:19
was the T2 level had the same injury.
1:22
So this may just be bone strain or stress injury
1:27
to the superior endplate. At the T1 level,
1:30
we actually saw the bone fragmentation of the
1:32
superior endplate, and it was a true fracture.
1:35
So use these STIR images.
1:37
They're quite useful.
1:38
When you're seeing these abnormalities,
1:40
you might also say, well, what about over here?
1:43
So this is the 2, 3, 4, 5, C6 posterior elements.
1:49
This ends up just being a small hemangioma of the
1:52
vertebral body that was seen on the CT scan.
1:56
So compression fracture, superior endplate
2:00
of T1, as well as stress injury without fracture,
2:04
superior endplate of T2 in association
2:08
with the Jefferson burst fracture.
