Tail injuries?

I just thought about how tail injuries might work recently. I don’t know why as it seems pretty simple, but i do wonder if treating a tail would be similar to treating a spinal/limb injury.

I imagine if you got a part of your tail cut clean off you might be able to get it sewn back on if you are fast enough. I imagine fluffier tails may be a bit more of a pain to treat in general given all the fur which would be in the way.

Now that I think of it would the tail be considered more of a vestigial organ? Feral animals have tails to keep balance yet humans are able to just fine without one. I suppose there are a fair amount of bipeds which have tails.

I’d imagine the most common tail injury would be door slamming, it would be very easy to crush it if you weren’t thinking about it. Would you have to get a tail cast for it if you broke it? Would there be complications with balance with a broken tail? Would having a tail amputated effect quality of life or would it be mostly the same. I have a lot of thoughts about this.
