Columnar midfoot anatomy.

0:02

Let's go.

0:04

The midfoot consists of a lateral column,

0:08

a middle column, and a medial column.

0:14

Let's break them down.

0:16

First, the lateral column.

0:18

It consists of the articulation of M4,

0:21

fourth metatarsal, and M5 with the cuboid.

0:26

It's pretty flexible, actually.

0:29

The middle column, it's rigid, which explains

0:32

why it's prone to injury of the ligaments.

0:36

13 00:00:36,535 --> 00:00:41,495 It consists of the C2 and M2 articulation

0:41

and the C3 and M3 articulation and

0:45

all the structures in that line.

0:47

It's the most rigid.

0:50

Then finally, the medial column.

0:52

It's the articulation between C1 and

0:55

M1 and this one's pretty rigid too.

0:57

It just happens to be stronger and not

1:00

quite as rigid as the middle column.

1:04

This columnar anatomy is going to

1:06

be very important when explained.

1:08

The different types of convergence and

1:10

divergence that occur as a result of

1:13

failure of the Lisfranc mechanism.
