Deltoid Ligament: Sagittal Plane
HIDEInteractive Transcript
0:00
Sagittal projection for the deltoid, not my
0:03
most favored nation status, but we do get an
0:07
excellent look at the tibia and the medial
0:11
malleolus with the anterior fibunculus,
0:14
the interfunicular groove, and the posterior
0:16
funiculus, which should be described if there
0:19
are injuries in any one of these locations.
0:24
But my main objective is to show you
0:26
the deep deltoid in this projection.
0:28
We've got the anterior fibers of
0:30
the deep deltoid, and the posterior
0:32
fibers of the deep deltoid on T1.
0:35
We see them on T2 with some fat suppression.
0:38
Not so much on gradient echo due to magic angle
0:40
effect and due to volume averaging phenomenon.
0:44
Now what about the superficial ligaments?
0:46
That is not really the strength
0:48
of the sagittal projection, so I'm
0:50
not going to do a deep dive on it.
0:52
But if we were to try and pick out portions
0:54
of the medial complex that could be relevant,
0:58
one would be the transverse structure
1:02
running from the calcaneus to the navicular
1:05
known as The superior calcaneonavicular
1:08
ligament, and we see a little bit of it.
1:10
Now, we already said that this ligament is
1:12
going to run in this direction, like this.
1:15
And from the tibia, more superficially,
1:18
you're going to see fibers that
1:19
come down to it and meet it.
1:21
And this is known as the tibial spring ligament.
1:23
We've also said previously, there are
1:25
actually three components that get gradually
1:28
thinner of the spring ligament complex,
1:31
and those have been described in detail.
1:33
in the axial or paraxial
1:35
projection with the toe pointed.
1:37
So, now, I'd like to, uh, ask you to
1:41
go back and review some of the other
1:44
projections, like the paraxial with
1:47
the foot plantar flexed and the coronal.
