Stress Fractures

HIDE
PrevNext

The next big thing I look for, um,

0:03

is stress fracture of the metatarsals.

0:05

Very common, um, to see that.

0:08

And what you're gonna do is you're gonna basically gonna

0:10

look at each metatarsal bone separately, scroll

0:13

through them, and you're gonna want to check

0:15

for any bone marrow edema, any fracture,

0:18

any periosteal edema, or new bone formation.

0:22

When you have a stress fracture,

0:23

there's a spectrum of findings.

0:25

If it's very mild, you might just see a normal x-ray,

0:28

and then you go to MRI

0:29

and you see bone marrow edema in the shaft

0:32

of the bone will show a picture of that.

0:34

If the patient keeps running, uh,

0:37

you might have an actual crack in the bone

0:39

and so you're gonna wanna see an actual line

0:41

going through the cortex.

0:43

So there's a variety of findings,

0:44

but usually you're gonna see bone marrow edema kind

0:46

of in the mid shaft of the bone,

0:49

and that is a very important finding to look for.

0:51

Here's the sagittal images,

0:53

and we also can look for bone marrow edema

0:57

in the metatarsal shafts.

0:58

This case is, uh, showing an example of relatively normal,

1:02

just giving you, um, just kind of pointers of what is,

1:05

what is a search pattern do to make sure you don't miss.
