When they drop their tails  they wiggle for like 20 minutes  ..  maybee it was just a nervous reaction to the impact .. I would think he would be  fine  but keep an eye  on the tail to make  sure the tip dosent die  and  get  necrotic ..

While I was moving my leo from one house to another in the car, somehow he got his tail pinched and half of it rattled and rattled on.. It eventually fell off, because the tail had separated internally. If your leopard gecko's tail tip is rattling around, I suspect that the tail was broken where you're seeing the wiggling going on, and it will stiffen up and fall off in a day or so. Leopard geckos are tough little guys, his tail will heal once it drops and it will regrow to a little fatty nub. Like Doomtrooper said, he should be fine, but keep an eye on him.

+1 to both of the above comments

Leopard geckos, like many lizards, have fracture planes between the caudal vertebrae in their tails (still part of the spine, by the way, albeit a less significant portion).  That twitching response is an involuntary defense mechanism that's activated when the tail breaks along one of those planes; you can imagine that if that tail piece came off in the paws of some predator, that jerking wiggling tail could preoccupy it just long enough for the gecko to escape with its life.  Another part of that mechanism tells the vessels just cranial to the fracture to clamp shut, keeping the lizard in the above situation from bleeding to death.  Unfortunately, if the tail is still attached (as in your case), that means all tissue caudal to the fracture no longer gets oxygen and nutrients from the blood, so that tissue dies.  Like Ihkura said, I would expect the tail tip to necrose over the next few days and fall off on its own.  However, if the damage seems to be ascending cranially PAST where you think the damage occured, I wouldn't wait to get your little guy to the vet!  Of course, on the other hand, maybe he was just twitching his tail cause he was annoyed that you dropped a keyboard on him?!  Maybe he'll keep it?  Stranger things have happened.  Keep us all posted on his progress!

...and hopefully you learned something important about the dangers of handling.  Some of the saddest and most devestating exotics injuries we see come through the vet school are caused by the most loving owners.  Owners so loving they just can't resist carrying their lizard places on their shoulder (and other common scenarios) only to have some freak accident result in a painful and often terminal injury to their beloved pet.  BE CAREFUL!

thanks you guys. his tail is just getting pal so i think it will result in the part that got smashed will most likly fall off over the next couple days. it's just sticking stright up right now. My hugest hope is for that tip of the tail to just regenerate and become normal... i'm gonna miss that tail though! ;c 

i touched his tail and he didn't move at all when i touched the part that was sticking straight up and the very very tip of it (where it goes to a point) and i was able to move it but he couldn't 

Now he's actually moving it! i think his tail migh just regenerate back!

Hey! How's the tail looking now?

it's looking ALLOT better, thanks :). He's doing great except he's just a little skiddish now, but i understand why lol.
