Let's talk briefly about the oft forgotten
0:03
superficial peroneal nerve,
0:05
which gets a lot more attention in the knee.
0:09
The superficial peroneal and deep peroneal
0:11
nerve may divide higher up
0:14
around the fibular neck, but the division
0:17
is very variable from top to bottom.
0:20
The superficial peroneal nerve courses up higher
0:23
in the leg, within the peroneus longus muscle,
0:26
it innervates the peroneus longus muscle and
0:29
the peroneus brevis, and then it emerges through
0:32
the peroneal musculature about halfway down
0:35
the anterolateral aspect of the lower leg.
0:38
It exits at a level of defect in the
0:40
crural fascia, about 12 centimeters above
0:43
the ankle joint, and the remaining portion
0:46
from this point down is purely sensory.
0:49
Inferiorly, it divides into two
0:51
branches, which we actually see.
0:53
There's one branch right here, very small.
0:56
Here's the second branch here,
0:58
also very small, right underneath the skin,
1:00
and these are known as the medial and
1:02
intermediate dorsal cutaneous branches.
1:06
The superficial peroneal nerve reaches the
1:08
dorsum of the foot where it supplies the toes
1:10
with the exception of the first web space,
1:13
which is owned by the deep peroneal nerve.
1:17
You might say, "Well, can I
1:18
really track these nerves?"
1:19
It's pretty tough, to be honest with you,
1:22
but a terrific landmark to assess these
1:25
nerves is the extensor hallucis longus.
1:29
So, if we look at our friends Tom, Harry, and
1:31
Dick, and we just stay with Harry all the way
1:34
down into the toe, we're gonna be in the vicinity
1:37
of the superficial peroneal nerve, and there
1:41
is Harry right there, and there is one of the
1:44
divisions of the superficial peroneal nerve.
1:48
The superficial peroneal nerve, a pure
1:51
sensory nerve in the foot that takes care
1:54
of the dorsal sensation of the foot,
1:56
with the exception of the first web space.
