@precordialthump I totally forgot about the EKG library! Awesome stuff. Keep up the great work (when do you sleep?!) 257 days ago
@emeducation Perfect, thanks for the suggestions! Turns out one is co-authored by Jeff Tabas. He already gave them all books. 257 days ago
Recommendations for an EKG resource to review bread & butter cases for senior residents? Pre-graduation panic setting in for our residents. 258 days ago
@danipedia Good point. I use the studies to convince the trauma consults NOT to get c-spine imaging on EVERYONE (citing distracting injury)! 263 days ago

Beware the hidden tibia plateau fracture

Posted Feb 11 2010 12:00am
Find the fracture in this patient with blunt knee trauma.

As a general rule, plain films are insensitive in ruling out orthopedic injuries. One particularly tricky area is the knee. This 2-view knee series above is normal.

Did you know that the sensitivity of picking up knee fractures is as low as 79% with a 2-view series and 85% with a 4-view series? With the advent of CT imaging, more and more subtle fractures are being found.

Here is the same patient with 2 oblique views:


Although oblique views add more sensitivity in detecting fractures, these are also normal. However in the CT reformats of this patient's knee, the fracture becomes obvious - a depressed lateral tibial plateau fracture.



Beware the "invisible" tibial plateau fracture on plain films!

CT image the patient's knee especially if unable to bear weight after significant blunt trauma, despite plain films.
