Tibial Nerve
HIDEInteractive Transcript
0:00
Let's talk tibial nerve, and therefore,
0:03
we're talking about the anatomy of the tarsal tunnel.
0:06
Not the anterior tarsal tunnel,
0:08
but the main medial tarsal.
0:12
You can use the mnemonic Tom,
0:15
Dick, and very nervous Harry.
0:19
So, Tom, the tibialis posterior.
0:22
Dick, the flexor digitorum.
0:24
Very veins burying the posterior
0:27
tibial artery, which is right in here.
0:29
And then nervous, the nerve, posterior
0:32
tibial nerve, or the tibial nerve.
0:35
And then hairy, the flexor
0:36
hallucis, tendon, and muscle.
0:39
A useful, cute mnemonic.
0:41
If we follow the tibial nerve inferiorly,
0:45
it's gonna bifurcate into two nerves.
0:47
Let's follow it.
0:48
There it is bifurcated.
0:49
It's still bifurcated into a
0:51
medial and lateral plantar nerve.
0:55
Right next to it is the neurovascular,
0:57
or the vascular bundle, or pedicle.
0:59
These are veins.
1:00
There's the posterior tibial artery
1:02
with a little more flow void.
1:03
There's another vein around it.
1:05
Let's review again.
1:06
Tom, tibialis posterior.
1:08
Dick, flexor digitorum.
1:10
Harry, as an excellent landmark, for right
1:13
behind it is the medial plantar nerve.
1:15
Just lateral to it is the lateral plantar nerve.
1:19
There's the posterior tibial
1:20
artery and some surrounding veins.
1:22
And for your pleasure, the superficial
1:25
retinaculum, or laciniate ligament.
1:28
Thank you.
1:28
We're going to tackle the
1:29
plantar nerves separately.
