The sural nerve is formed by the union
0:02
of two branches, the medial sural nerve
0:04
from the tibial nerve and the lateral
0:07
sural nerve from the peroneal nerve.
0:10
The sural nerve proximally sits between,
0:13
although we're a little more distal than this,
0:15
but between the two heads of the gastrocnemius.
0:18
Here we see it sitting just lateral to the
0:22
Achilles and just behind and medial to the
0:25
lesser saphenous vein and a branch thereof
0:28
on both the T1 and the T2 weighted image.
0:32
Now distally, as we follow the sural
0:34
nerve down, and there it is, it's
0:37
gonna branch into two components.
0:39
The lateral dorsal cutaneous nerve,
0:41
we're gonna see it branch in a moment.
0:43
Here it is right here.
0:45
It gets a little bit confusing because
0:46
we've got saphenous, the lesser
0:48
saphenous vein and its branches.
0:50
So we're going to see a branch right there.
0:53
The anterior branch is the lateral
0:55
dorsal cutaneous nerve, and the posterior
0:57
branch is the lateral calcaneal branch.
1:01
And that is the one right there.
1:03
We follow it right next to the calcaneus.
1:06
It is often injured in a lateral
1:08
approach to fixing a calcaneal fracture.
1:12
This one or its cutaneous
1:14
component can also be injured.
1:17
When there is lesser saphenous vein stripping in
1:20
somebody that has venous insufficiency syndrome.
1:23
The sural nerve, a nerve that is injured
1:27
iatrogenically, more common than it is from
1:30
a traumatic event or from a mass or tumor.
