WWWTP #16 Answer…

Elbow XR, Orthopedics, Trauma, WWWTP, XR


Several days ago I asked What’s Wrong With This Picture (WWWTP #16):

Elbow fx 3Elbow fx 2Elbow fx 1

Here’s what radiology thought:

1.  There is a fracture of the lateral epicondyle with displacement.

2.  There is subluxation of the capitellum anteriorly.

3.  There is a minimally displaced fracture of the olecranon process.

4.  There is a large amount of soft tissue swelling adjacent to the elbow, most pronounced laterally.

5.  Exam is somewhat limited due to lack of true lateral radiograph.

 

#1 is fairly easily identified on all 3 radiographs.  #2 is readily apparent if you apply the anterior humeral line to the radiograph, see link below for further details.  #3 can be best identified by the lucent line on the latter two radiographs.  #4 is apparent also on the second two radiographs.  #5 is a true statement, it is not a great lateral radiograph.  However, can you imagine the difficulty the radiology tech had trying to get anatomic landmarks when it is this swollen?

Hopefully you got all the findings!

Here is a brief review of the anterior humeral line of the elbow from radiopaedia.org:
