This is basic MR, maybe, maybe not so basic,
0:03
but let's talk classification systems.
0:05
And I'm going to go with the most basic one,
0:08
which is the Quénu and Kuss classification
0:11
classification from 1909, about when I was born.
0:16
It's divided Lisfranc fracture
0:18
displacements into three categories,
0:21
homolateral, isolated, and divergent.
0:25
So what do we mean by this?
0:27
Well, homolateral is the most common.
0:30
In other words, all five of the metatarsal
0:33
bases all go in the same direction.
0:36
And they usually go this away.
0:39
Then we have what I call isolated injuries.
0:42
This is the least common.
0:44
It consists of displacement of
0:46
perhaps one or two metatarsal bones.
0:50
Usually, in my experience, it's the second
0:52
and the third that may slide or slip a little bit,
0:55
but not the others.
0:57
Then you've got the divergent one,
1:00
which is rather catastrophic looking.
1:03
It involves subluxation or dislocation of
1:06
the first metatarsal medially while the
1:09
other metatarsal bones move laterally.
1:11
So if we look at the columnar
1:14
presentation, we've got three columns.
1:16
A medial column, a middle column,
1:18
and a lateral column in the divergent form.
1:21
The middle column and lateral column
1:23
go out, or stay where they are,
1:25
and the medial column goes this way.
1:28
So the separation here is very dramatic.
1:31
This is a very simple diagnosis to make.
1:36
There are other classification systems.
1:38
There will be a story for another day,
1:39
such as the Myerson classification system,
1:42
and you can Google that at your leisure.
