What can a vet do for this feral kitten's legs?

I found a feral kitten four weeks ago and it was in critical condition. The hind legs had been cut off, and his front right paw had nerve damage. He was severely starved and dehydrated as well.

The legs had scabs and were not infected. They didn't think he'd make it, and thought I should consider putting him down.

I didn't, and he has now doubled in size and seems healthy, but the scabs came off and his legs are open wounds. It almost appears like the bone is sticking out at the end of his right leg, and there's not much skin.

Has anyone experienced what they do for the stumps in situations like these? He's been at the the vet several times, but they thought he'd die, and he had to get healthier so wouldn't discuss it.

Now he's going in again Friday, but I'm not sure what to expect. I'm scared for him and have fallen immensely in love with him.
