Don't worry about it, this method is usually reserved for a bad mangled limb that you can't get to stop bleeding. By removing the leg at a lower joint you then have a smaller area of bleeding to control. But in your case that is a non issue. She may favor the leg, and it may be unsightly, but if she thinks it’s in her way she will remove it on her own. I have had a few T's pull brand new legs out a mangled limb, so just leave her be.I doubt he has any feeling in or control of the leg, looking at the way it's bent and how it doesn't move. Link to a guide on safely taking legs off spiders? A little nervous.
No, I have a picture somewhere of a M. Robustum that escaped and met the cat in the kitchen a few weeks later. His leg was mangled beyond all belief. It had some spot mold on it at one point, it turned black, it was curled and useless, but when molt time came a full sized new leg came out of that mangled mess.It's a him! :razz:
but seriously, you wouldn't worry about a dead leg attached to a live spider... like, rotting, or something?
