Salter-Harris Injuries

Okay, our prior vignette, we sort of drew cartoon
0:04
diagrams and talked about the significance
0:07
of Salter-Harris injuries, where we talked
0:08
about what the different classifications
0:11
are, the importance of the body part that's
0:13
involved, and the difference between a
0:15
horizontal and a longitudinal or vertically
0:17
oriented or classified, uh, physeal injury.
0:21
I want to start out with the most basic
0:23
one, which is actually pretty uncommon.
0:27
Uh, and that is Salter-Harris Type I injury,
0:29
meaning that it involves only the physis.
0:32
And it's very difficult to appreciate because
0:34
there may just be a slight separation.
0:36
The ankle is a good place to look because
0:40
you have other physes there for comparison.
0:42
For example, here's an injury to a patient
0:45
on the lateral side, and you see on the
0:47
coronal fat-suppressed fluid-sensitive
0:49
sequence, there's a little bit of bright
0:51
signal in the very lateral aspect
0:54
of that distal fibular physis.
0:56
Compare it to the physeal size and
0:58
appearance of the distal tibia.
1:01
The image on your right is the same
1:02
patient with contrast administered.
1:05
The reason that contrast was administered is
1:06
because we weren't sure what the pain was from.
1:09
So only after the MRI did we realize that it
1:11
was from a Salter-Harris injury and eliciting
1:14
more, more, more history from the patient.
1:16
So again, here is the normal physis
1:18
on the distal tibia, and here is the
1:20
abnormal physis showing separation.
1:23
But not involving the
1:24
metaphysis or the epiphysis.
1:26
So this is a Salter-Harris Type I injury.
1:31
It's still at risk for bony bridge
1:34
formation, but much less so than if it
1:38
was a higher-grade Salter-Harris injury.
