Most big non-avian theropods had reasonably long arms relative to body size.
Aside from tyrannosaurs, there are a few exceptions: the carnotaurines had
truly puny arms; and some 'megalosaur'-grade carnosaurs had rather short
arms (also extremely robust, especially the forearm). Among smaller-bodied
non-avian theropods, the compsognathids had rather small arms; and the
alvarezsaurs had small arms that were also highly specialized. There are
plenty of big theropods that had fairly long arms, including some
ceratosaurs, spinosaurs, allosaurs, the larger dromaeosaurs, and especially
therizinosauroids (probably not such great runners) and _Deinocheirus_
(likely a very-long-armed theropod, even though we don't have the rest of

Maybe that's when the prey would come in handy - to break the tyrannosaur's
fall. :-) Of course, if the prey was a _Triceratops_, it could turn out
badly for the tyrannosaur.
