Could be but I'm thinking things would get pretty western trying to get a cow hung up by her back legs. Especially working by myself.
I have done a tail block with lidocaine to push back in a prolapse.
All done with cow in a chute which is safer for both me and her.
I have had legs back and even a head back presentation but usually you can work between the cow's pushing.
If she won't quit straining, then I have used a tail block for that too
