Need a wheelchair... Parapelegic guppy :(

I think one of my guppies has a spine injury.
I'm about to euthanize it because it's obviously in pain, but wanted to make sure it's nothing contagious.

It doesn't look like swim bladder disorder- her head is pointed down, and her front fins, mouth, and gills are moving frantically, but her tail is curved and not moving at all. Sometimes she twists her front half, which lifts her off the substrate, but she eventually sinks again head-down.

Any ideas?
I already posted her in the memorial forum...

I don't think its anything contagious. I do think you should just euthanize it as I don't think it has any chance of survival. :( The best method I know of is to get water freezing cold (put some ice in some water and allow it to get really cold) and drop the fish in. She should die in about 2 seconds. If anyone knows a better method, or if this isn't as humane as I think, feel free to chew me out.

Temperature shock method (freezing)
This method utilises the coldest water you can find - a bowl of water that has been placed in the freezer long enough for the surface to freeze is good. The surface ice is broken and the bowl taken to the dying fish.
The fish is then captured and dropped into the freezing water. The difference between the temperature of the tank and the freezing water causes an instant fatal shock to the fish nervous system stopping all organ functions instantaneously - anyone who has found themselves suddenly in water that is much colder than your body temperature will know the feeling when you initially can't breathe (people have died of heart failure under similar circumstances), it is like that but much more severe and sudden.
A variation on this is freezing alcohol (pure or vodka)
Stress is caused in the handling of the fish, but in most of the methods the fish must be handled - however this handling is brief.

Diseases aren't my thing but don't fish curve like that with dropsey? Possible TB as well? Just throwing ideas out there.
