My Favourite Tidbit of "English Language Use" Lately

I was doing a little homework on hemmorhagic shock... and I came across this sentence beginnin with:

"Recent Studies involving URBAN PATIENTS WITH PENETRATING TRAUMA..."

I know it was a medical academic article, but couldn't they have just written "Minorities getting shot or stabbed?"

What other kind of PENETRATING TRAUMA IS THERE?

(Somebody is going to come up with an anal sex joke, so save it.)
