Case: Volar Plate Injury

HIDE
PrevNext

0:00

So this person comes in

0:02

after having suffered a hyperextension

0:04

injury to the little finger.

0:06

So radiographs were performed with these three projections,

0:09

frontal, lateral, and oblique.

0:11

And now we have them magnified, focused on the finger

0:14

of interest that is the little finger or the fifth digit.

0:17

And so as we look at the little finger here, we can identify

0:21

that the metacarpal phalangeal joint is maintained.

0:24

However, the proximal interphalangeal joint

0:27

or the PIP articulation shows a bony fragment.

0:31

When we go to our lateral projection, we now identify

0:35

that this fragment is along the volar aspect.

0:38

There appears to be some combintion.

0:41

The proximal phx shows mild dorsal subluxation

0:46

with respect to the metacarpal head.

0:48

The remainder of the osseous structures appear intact.

0:51

The DIP or distal interphalangeal joint space is preserved,

0:55

and the frontal projection reveals no additional injuries.

0:59

And so this represents a volar plate injury.
