Broken derailleur

I have a Campagnolo Chorus 10 speed with 50/34 rings and the front derailleur cage is broken. Will other derailleurs work, as long as the cable pulls from the same direction?

Yes, Mostly

A replacement 10 speed Campy Chorus derailleur replacement runs from $16 used to $40 new on your favorite auction site, so a replacement won't break the bank.

Front derailleurs have fewer limits on them than rear derailleurs, and a road front works just as well in friction as with integrated shifters. Since the shifter is what controls the cable pull, just about any similar speed derailleur will work given the same chain width, but I'd go for a direct replacement.

How'd you break the cage?

Multiple episodes of chain suck over the years must have bent the thing enough times to cause metal fatigue. I think the clamp came loose a time or two.
I'm not exactly the master of maintenance and I tend to let things go until they fall apart or fail. The bike has 35,000 miles from me and I bought it used.

I'll check out e-bay but I was wondering if something I have lying around might work.

Chain suck is a symptom of a worn drivetrain. You may need more than a new derailleur then. Worn chainrings, stretched chain, worn out rear derailleur springs can all contribute to chain suck. If your chainrings are worn and the teeth look like shark fins, chances are that your cassette cogs are also worn unless you've replaced them already.

It wouldn't be a bad idea to see what your friendly neighborhood bike shop mechanic has to say. You'd probably get a few opinions here if you can post pictures too.

The chain and cassette have been replaced a few times and the rings once. You're right, it all probably needs to be freshened up. Maybe I'll just get a new bike instead. What's that retirement account for, anyway?

Thanks for your insight, btw.
