Wk 4, Case 5 - Review

HIDE
PrevNext

0:00

This is Pediatrics week 4 case 5 and

0:03

we have radiographs of the forearm

0:06

and wrist of a six-year-old child with fall

0:09

onto outstretched hand and so

0:12

of course the injury that we're most suspicious of

0:15

is a distal radial and ulnar fracture and

0:18

sure enough. That's exactly what we're getting on this image. You

0:21

can see that there is a subtle buckling

0:24

right here.

0:27

At the metaphysis or maybe you'd say the metadiaphysis of

0:30

the distal radius and

0:33

there's also just a very slight

0:36

disruption of the normal trabeculae right in

0:39

there take a look without The annotation. You can

0:42

see it's a little bit more Lucent and there's a little bit

0:45

of a Sawtooth pattern right in here

0:48

where those trabeculy have been fractured. And in

0:51

fact the fracture line in this case extends all the way

0:54

up to the fisces and it turns out that in many

0:57

cases of distal radial fracture, even though

1:00

it's not clearly disrupted at the

1:03

fisces. The fracture does extend all the way up. It also extends all

1:06

the way across to the other side. This is called a buckle fracture

1:09

or a Taurus fracture and that Taurus just

1:12

as Latin for bump or

1:15

a hump. And if you're looking at the Contour of the

1:18

cortex, you can see just a very subtle little bump here.

1:21

It's the Clue the other area you want to be aware

1:24

of is the ulnar styloid in this case.

1:27

Hardly even ossified but it's frequently fractured in

1:30

association with a distal radial fracture.

1:33

Over the years people have come up with names for these things colleagues fracture

1:36

is one orientation of the

1:39

fracture Smith fracture. All the eponyms may

1:42

not be helpful here. The key thing is it's a sequela of

1:45

following onto an outstretched hand. It typically

1:48

does not disrupt the articulation between

1:51

the distal radius and the carpus of the hand but this

1:54

metaphaseal or meta-diaphaseal bone

1:57

is where the fracture occurs on lateral view. You can

2:00

see just a very subtle angulation right here in instead

2:03

of a natural curvature that your clue of the

2:06

fracture and these patients tend to

2:09

do quite well and not require surgical repair given

2:12

the non-displaced status of the fracture. That's the end

2:15

of the case.

Report

EXAM: Left Wrist radiographs (X-ray), 2 views

INDICATION: 6-year-old girl with fall onto outstretched hand

TECHNIQUE: AP and lateral radiographs of the wrist were obtained

FINDINGS:

2 view radiographs of the left wrist reveal a torus fracture of the distal left radius, likely extending to the physis, but without significant displacement. Alignment at the radial-carpal articulation is anatomic. The bones of the visualized hand appear normal.

IMPRESSIONS:

Distal left radial torus fracture.
