Defense should not be thought of strictly in terms of breaking a limb (TRex
leg in this case). A simple knock down may be all that's needed, the 
hadrosaur then utilizing this opportunity to run while the rex tries to
pick itself up. Anything that slows down the predator can be translated
into escape and survival.

I recall, from a nature show, an instance where a zebra, chased by a
lion, broke the lion's lower jaw while kicking with its hind legs. This
lucky shot slowed this lion down for sure! (I can't recall what happened
to the zebra, tho, probably killed by other lions.)
