1.5 Tesla imaging of the medial side of the ankle.

We're getting oriented with our friends Tom,
0:09
the tibialis posterior, Dick, the flexor
0:11
digitorum, and Harry, the flexor hallucis
0:13
longus with our neurovascular bundle secured
0:17
by the laciniated or superficial retinaculum.
0:21
We see the oblique, almost curve-shaped, thick,
0:26
dense, strong fibers of the deep deltoid.
0:30
Now if we scroll a little higher, we still
0:32
see them. If we scroll a little lower,
0:34
they become a little bit more wispy.
0:38
And then on top of them is a shell.
0:41
And that shell consists of, from back to front,
0:46
or from front to back, the superficial ligaments.
0:50
So anteriorly, we're going to
0:52
have the tibionavicular ligament.
0:54
Then the next one is going to
0:55
be the tibiospring ligament.
0:57
It's going to go to a ligament.
1:00
And we said that one's
1:01
probably the most important
1:02
of the superficial ligaments.
1:04
So let's see if we can hock or
1:07
follow the tibiospring ligament.
1:10
There's our superficial shell.
1:12
Let's keep following it.
1:13
And now we are into, right here, we're into
1:17
the superior calcaneonavicular ligament,
1:21
which has attached to this superficial shell.
1:24
So that ligament is diving down to
1:26
reach a horizontal ligament, like you've
1:29
seen in an earlier vignette diagram.
1:32
Now what are the other components
1:34
of the superficial ligaments?
1:36
They would be the attachment to the calcaneal
1:41
ligament, and the tibiotalar ligament,
1:43
also known as the posterior tibiotalar ligament.
1:47
So that's the axial projection
1:50
and orientation for the deltoid.
1:53
But not nearly as critical as we'll
1:55
see in the coronal projection.
