Default Neurergus Strauchii Strauchii limb regeneration photo documentary

Hello members,

I am experiencing a special situation with one of my newts, since I saw no similar treat in the forum I thought I share it with you.

A week ago (10 nov) my Neurergus Strauchii Strauchii juvenile had an accident. A tankmate saw his back paw as a meal and unfortunately his leg was quite injured after that. His leg was still attached but angled and he couldn't move it anymore, probably his leg muscles were ripped. I waited 2 days (12 nov) for it to maybe recover, however it was already to late. His resting leg tissue was degenerating and began molding. So I needed to amputate his leg. I did this very carefully with a sterilized nail scissor. I cutted the leg off as close to his hip as possible, to create a small surfaced wound to minimize the chance of infection.

In the bottom picture you can clearly see his leg bone was still intact, but the muscles around are missing. That explained why he could not move that paw anymore. Click the image to open in full size.

This was right after the amputation.

After the amputation is returned him to his tank. I threat the water with ESHA Optima and ESHA Minaroll,
which are stimulators of the immunesystem and vitamin preparations. T
his will back him up in his leg recovery. At the time he still ate food and does so now, so i dont think he became infected.

Day 14 (week 2) post amputation:

The little newt is still happy and healthy. His wound is slowly recovering and it's beginning to repigment into black. I am not sure if his leg will regenerate, but if it will, it will be a very patient process.

It should regenerate another leg, Iíve amputated lots of times and always new limbs grow back.
I have done it with juvenile animals and adults ,one adult grew back a stump instead of a foot but isnít a problem

Good to know, since my newt is juvenile I think his chances to regrow his leg completely are good.

Day 21 (week 3) post ampuation:

There is deffinetely progress now. His bone grow a bit longer and the stump is a bit bigger. His wound is now completely covered in pigmented skin. His legbone stick out a bit, it seems to grow on its own, which I did not knew was possible.
I guess his leg tissue will cover his bone someday, then his paw can be remodeled.

Day 28 (week 4) post amputation:

His stump is growing now. Very fascinating to already see a difference between day 0 post amputation. In the previous week his leg bone was still sticking out, but today his bone is covered in epidermal tissue.

His stump is probably end-dedifferentiation phase and is starting to proliferate newly formed bone and epidermal tissue cells, see the underneath picture. I predict the following week his leg will grow some length.

Day 35 (week 5) post amputation:

This week his paw is growing very well! A few millimeters are added in length. Also his stump can move like he uses his former leg. So the hip-leg muscles, which were ripped, did regenerate back this week, and still do.

This week his stump grew a bit longer en bigger, it developed a bit more limb-like, instead of a pointy stump from last week. Probably in like 3 weeks his toes and knee joint will develop.

Day 49 (week 7) post amputation:

Progress! The little newt is growing a few toes! I did not expect his foot is developing first, before his knee joint. Well as you can see, there are developing 3 toes for now. He also moves his mini-leg just like his others, so the hip muscles are completely regenerated at this point.

Day 56 (Week 8) post amputation:

His leg is growing very well. The knee joint is developing now. The newt also uses his regenerated paw when he walks. Very cool to see his new leg is moving around so much.
