When my veiled chameleon had MBD he had the same problems with his legs. I don't think you caught yours in time like I did,but your chameleon will make it. There is a bulb called Active UV Heat that can reverse MBD and Exo-Terra makes something in the water that can also reverse it. In the stage your chameleon is in right now. There is surgery, that can be done. They replace the fractures in the bones with articial bnes, but it costs alot of $$$$. experience with what constitutes normal growth, failing to optimise their calcium regime and thus getting deficiencies. Unlike the acute cases above, these may be relatively mild in that the chameleon is getting some but not enough calcium and the most common manifestation of this is the small deformed juvenile. In these cases we see the failure to mineralise bones causing general deformity, bowing of the legs and swellings around joints of the legs and even ribs. Treatment results are directly related to the age at which it is instigated i.e. how much growth potential remains and are detailed above. There are cases where this can be precipitated in the females/subordinate males when multiple housed in that the suppressive effects of the male on a female or subordinate males seems to result in the oppressed animal growing in this way. The regime of supplementation itself may be sufficient in these cases, and the dominant animal grows normally. One would suppose that this still relates to calcium and the loss of supplementation during the increased time it takes the lesser animal to feed, but a physiological suppressive effect from the dominant animal may also be involved. The effects can thus be reduced by either hand feeding lesser animals whilst maintaining animals in groups, or better still, by rehousing all subordinate chameleons on their own.
