This is a person with wrist pain after a fall.

0:03

On the outstretched hand here we have three projections

0:06

of the wrist, our frontal, our lateral, and an oblique.

0:11

And as we look at the distal radius contour,

0:14

we can see an abnormality along the metaphysis.

0:18

On the frontal projection, there's a transverse lucency

0:22

noted through the metaphysis, just proximal

0:24

to the distal radial ulnar joint.

0:26

We wanna look at the congruity of the distal radius

0:30

articulating with the carpus, the width

0:33

of the distal radial ulnar joint,

0:35

and any additional fractures.

0:37

Here we see a small OCI fragment off of the ulnar styloid,

0:42

which is often an associated lesion.

0:45

The proximal carpal arc is here, mid carpal row,

0:51

carpal metacarpal junction.

0:53

All of those look intact.

0:54

The lateral projection helps to show the degree

0:58

of angulation, whether there's some dorsal angulation

1:02

as indicated here by buckling of the distal cortex.

1:06

We can also see dorsal tilt

1:09

of the distal radius articular surface.

1:12

The distal radius does remain coline with the lunate

1:16

and the capitate, so that's our typical relationship.

1:19

Distal radius, lunate capitate,

1:22

and third metacarpal scaphoid is here,

1:28

usually resides at about 30 to 60 degrees

1:31

to this carpal plane.

1:33

And the oblique projection does not reveal any

1:36

additional fracture patterns.

1:38

Sometimes can help to confirm

1:41

or suggest whether there's an intraarticular component.

1:44

We do not perceive a definite intraarticular component,

1:48

so this would be a distal radius fracture within the

1:51

colleagues type.
