Saphenous Nerve

HIDE
PrevNext

0:02

The saphenous nerve.

0:03

It lies medial within the adductor canal and then

0:07

it exits the distal canal between the sartorius

0:10

and gracilis, just distal to the knee joint.

0:14

It becomes subcutaneous in the medial aspect

0:17

of the knee and then it descends in the

0:20

subcutaneous region along the medial aspect

0:23

of the lower leg, coursing directly behind,

0:27

there it is right there, directly behind

0:29

our friend, the greater saphenous vein.

0:32

Probably the most common cause of injury

0:34

to this nerve, and there it is as we

0:36

go up, and here it is as we go down,

0:40

is stripping of the greater saphenous vein,

0:42

which is often performed for cardiac

0:45

bypass surgery or for venous insufficiency.

0:49

Let's follow the greater

0:50

saphenous vein nerve down.

0:52

There it is.

0:52

There's the vein in front of it.

0:54

There's the nerve.

0:54

There's the vein on T2.

0:56

Let's keep following it.

0:57

We can see it on this 3 Tesla

0:59

scanner, and then we lose it

1:00

momentarily, as it gets faint

1:02

and has an oblique course.

1:04

And then it comes back again a bit laterally.

1:06

So as we go down, it starts to

1:08

move a little bit posteriorly.

1:10

Now we've lost it again,

1:11

and there we see it, we find it again.

1:14

Just along this protuberance of the

1:17

anteromedial aspect of the talus.

1:20

The saphenous nerve, a nerve that is injured

1:23

more commonly, iatrogenically, than with a

1:26

primary process in the ankle joint or lower leg.
