Thanks for posting that skeleton pic. The rib joints are lower (which is what I thought) so the bumps wouldn't be the rib joints.

I hope there can be some resolution. Please consider taking her to a vet.

They are broken ribs.
It's very clear... the animal fell and broke them.

The "nodes" are the result of the animals attempt to heal itself.
this isn't because I'm suggesting that the owner has been throwing
it across the room or playing "frog baseball" with it
it's because these animals climb and fall in their cages.

I've said this before in other threads
There's often a kneejerking reaction post that usually appears
often in several forms around here... they include:
MBD
VET ASAP!!!
EGGS!~!!!!!
WORMS!
and MBD with EGGS and need to get to the VET combos
with NUTRITION thrown in to round things out.

All can be usually discounted if the poster can spend some time
and think things through to find logical reasons for their statements
BEFORE posting one of the above "catch all - non answers"
that way the person asking for help will get a good signal to noise ratio here.
We're all trying to help here.. I know that...

It's just if you're really trying to help then please include the reasons why
you believe your statements are true.

I happen to know what broken ribs look like
when I examined one of my sub adults that had a nasty fall
these are broken ribs no doubt
there isn't any sign of MBD nor is it gravid.
we're dealing with the aftermath of a impact injury.
sorry if I sound short but I'm trying to get out of the office asap
so I can feed my kids a bowl full of flies. ;D

You said..."little bumps on both sides of her ribs"....
You said..."she has only just started digging around the viv for the past week"...was she mated? Does she have a suitable place to dig to lay eggs? Has she laid eggs before? Is your other chameleon the same species?

nah she hasnt been mated, and has a deep pit to dig around in, she's never layed any eggs yet and neither has the other one, she is the same species aswell.

How often do you dust with the nutrobal? You said it contains D3 and vitamin A...both of which are fat soluble and can build up in the system. I dust most of the time with a phos.-free calcium powder (without D3 or A).
What do you gutload/feed the insects with?

Even if the bumps on the ribs were caused by a fall and broken ribs, IMHO its worth going over the husbandry to make sure that the ribs didn't break partly from weak and not just the trauma of the fall. Its also worth taking the chameleon to the vets IMHO. The vet could run tests to see if nutrient levels played a part or if it could be gout.

so does anyone know of a corfirmed cause of these bumps yet? i have read they are parasites, yeast desosites, broken ribs ect?!?
