Now let's move on to Salter-Harris
0:03
type 2 injury, also involving the ankle.
0:06
This time we're looking at the injury to
0:09
the tibia versus Salter-Harris type 1 injury we
0:12
saw before that involved the distal fibula.
0:15
Take a look at the plain radiograph first.
0:17
I'm going to blow this up
0:18
to make it a little bigger.
0:19
Again, adjacent physes are your friend.
0:23
This time it is the physis of the distal
0:25
tibia which is wider, more irregular
0:28
than the physis of the distal fibula.
0:31
What else do you notice?
0:32
You notice that there's a little
0:34
bit of periosteal reaction extending
0:37
up the metaphysis on the lateral side.
0:39
What does that mean?
0:40
That means that the injury involves
0:42
not only your physis, but also your
0:46
metaphysis, even if you don't see it.
0:48
Okay, so that virtually guarantees you're
0:51
looking at a Salter-Harris type II injury.
0:54
And what does that look like on plain film?
0:56
I'm sorry, on MRI?
0:57
Here's the MRI on your right.
0:59
This is a fat-suppressed,
1:00
fluid-sensitive sequence.
1:02
And look what you see here.
1:03
Indeed, look at the physis
1:04
here of the distal fibula.
1:07
Look at the irregular enlarged
1:09
physis of your distal tibia.
1:12
And here is the injury extending into the
1:15
metaphysis and causing subperiosteal fluid
1:18
formation and elevation of that periosteum.
1:22
So this is what you're looking at on
1:24
your plain radiograph, equivalent to
1:27
a Salter-Harris type II injury.
