Please note that this animal also appears to be suffering from a the effects of poor diet and poor lighting. I have seen many cases like this (with the shell deformed and the puffy skin around the limbs) Most often it is from diets that are VERY high in protein, lack of UVB lighting and overfeeding.

An outside arrangement where the creature could get natural sunlight and a good varied diet will be beneficial to helping this animal have a better quality life. The damage that is already there is most likely irreversible but at least it can be kept from getting any worse.
