Yea, you need a vet.
It looks like your cham has MBD.
The extra bends shown in the front arm,and the back leg are breaks or bends that should not be there.
this means there is not enough calcium in the body to supply to the bones to keep them from breaking.
You need a vet to determine what the caclium levels are at.
You mgiht be able to reverse some of the damage done, but without a vet, it will get worse, and soon it can affect the jaw, and eventually it leads to death.
also, I think you have a female, from the shape of the casque and the fact that at that size you should see yellow barring if it was male, which is another issue, as females need calcium to lay eggs (*bred or not, they still lay).
