Differentials of Insufficiency Fractures

HIDE

0:00

<v ->Now there is a differential diagnosis when dealing

0:03

with fractures in the subchondral bone.

0:07

I've listed some of the conditions

0:09

that can be associated with fractures

0:12

in this particular location including

0:17

the cases of infection tumor

0:19

and certainly neuropathic osteoarthropathy.

0:23

I show you a subchondral fracture here occurring

0:27

in that subchondral bone of the distal femur.

0:31

I'm gonna talk more about that in my last lecture

0:35

at this course.

0:37

I show you this case, you saw it earlier in the week.

0:40

This was a patient with congenital insensitivity to pain

0:45

and we're looking at a neuropathic fracture

0:50

separating the subchondral bone plate

0:53

and articular cartilage from the parent bone.

0:58

This was presented as an unknown case on a film panel

1:02

and indeed some of the people looking

1:04

at it thought the more likely diagnosis

1:07

was septic arthritis.

1:09

Certainly that would be

1:10

in the differential diagnosis of this.
