<v ->Okay, welcome back everybody,

0:02

and now we'll continue on with the final segments

0:06

of this four-day course.

0:09

And we're gonna turn our attention now

0:11

from transient osteopenia,

0:14

transient marrow edema, osteonecrosis, and talk a little bit

0:19

about subchondral insufficiency fractures,

0:23

terminology, pathogenesis, distribution,

0:27

and differential diagnosis.

0:30

As with the other segments,

0:33

I'd like to start with some terminology

0:35

so we're all speaking the same language.

0:39

A stress fracture is a general term for a fracture

0:42

that relates to repetitive normal or abnormal force

0:47

placed on normal or weakened bones.

0:50

So it's a general term.

0:52

We try to divide stress fractures into two types.

0:56

The first of these is a fatigue fracture

0:59

which is a fracture that relates

1:00

to repetitive abnormal force placed on normal bone.

1:06

And indeed, basically we see that in athletes.

1:09

The second is an insufficiency fracture.

1:12

It's a fracture that relates to repetitive normal

1:16

or abnormal force placed upon weakened bone.

1:20

So I'll try to be careful as I use those particular terms

1:26

during this lecture.
