how do you remove the broken pivot bar

Do you know how to remove a broken pivot bar that broke off while still in the window? Any suggestions on how to remove the piece left in the window Thanks

It broke off at the screw hole closest to the head of the pivot bar and the rest of the bar is stuck inside of the window.

I just had to replace two of them in the same window. Since they was older windows the bar that was broke was stuck, so i took a small nail and stuck it in the screw hole, and gave it a few taps with a hammer. It loosened it up enough that i could use something to press against the bar and move it enough to get a hold of it with some pliers. it came out easy enough

I had a similar issue. Two pivot bars, each broken off with a portion left inside. After struggling to extract them for (thankfully) not too long using needle nose, nails, etc... I stumbled into any easy solution. I was able to simply push the piece back further inside the window, out of the way of the new one. Easy peasy! Not sure if every brand/model of window has that extra hollow space behind the bar like mine did, though. Cheers!
