We're focusing on the anterior extensor compartment.
0:03
Let's talk about the anterior tarsal tunnel space.
0:07
Some of you have watched a few vignettes on the
0:09
tendons, but the space is formed deep boundary by
0:13
the talus and further inferiorly by the navicular.
0:17
So here's the navicular.
0:19
The superficial boundary is going to be
0:21
formed by the extensor retinaculum, which
0:23
you might have heard about ad nauseam.
0:26
So now let's go up a little bit higher
0:28
and we find the vascular bundle.
0:30
And then just lateral to the vascular
0:32
bundle, we're going to find the nerve bundle.
0:35
And the nerve bundle may stay as a single
0:37
bundle, but it often divides at or two to
0:40
three centimeters below the joint space.
0:43
So there we actually see it
0:44
dividing into its two bundles.
0:46
The lateral bundle we sort of
0:48
lose because of the curvature.
0:49
Maybe we see a little bit of its free edge there.
0:52
And the lateral bundle provides nerve supply
0:55
to the extensor digitorum longus and the
0:57
extensor hallucis, and also to the sinus tarsi.
1:00
And a few other structures.
1:02
It'll also give off some superficial branches.
1:05
The medial bundle will head off medially,
1:08
so let's go down and see if we can track it.
1:11
There it is right there.
1:12
There it is right there.
1:13
And it's gonna continue to head medially
1:16
and sit in front of the navicular headed
1:18
towards the location of the great toe where
1:22
it provides sensation between the first and
1:25
second great toe and the dorsum of the foot.
1:27
When this nerve is irritated, sometimes
1:29
that's confused with a spine problem and
1:32
the patient ends up with a lumbar MRI.
1:35
That would be the deep portion or medial
1:37
portion of the deep peroneal nerve that provides
1:40
sensation between the first and second digits.
