MBD or injury? Help my little guy.

My 6 month old chameleon may have MBD. I have given him proper UV lighting, glut load and dust crickets, drip system, misting, and humidifier. His housing is not the issue. I'm worried he injured his back legs and now he has MBD. I haven't seen anything regarding a broken bone causing MBD. It's seems to be the other way around.

After his injury, his back legs and hip turned brown. He didn't use them or turn green for about an hour. 2 hours later he was crawling around, hunting, and showing normal behavior. This was 6-7 weeks ago. The cause of the injury is still in question because I poorly trusted someone to check on him while I worked a long shift. I have not taken him to a vet because there isn't one close to me that takes exotics (unless to euthanize :( ).

The past 10 days he's been showing signs of MBD. He still hunts crickets and attempts to crawl but his back legs are weak. I have been giving him flukers repti-boost (.3 cc for his weight) and half his cricket diet. I give him a calcium d3 dust to his crickets every other day. I only handle him if necessary. I also replaced his UV lights just in case.

He stays on the bottom of his enclosure and doesn't attempt to go to the top. I have a hammock for him with plenty of branches to reach the top safely. I put his lighting at the bottom along the side of his enclosure at almost a 90 degree angle. I also have a low heating pad under his enclosure. He has repti bark but to make it easier to move I covered the bottom with paper towels. He also has a pathos plant that he climbs in to sleep.

He's pooping normally. His legs essentially look weak. He doesn't seem malnourished, dehydrated, or emaciated. He can grip with his feet but doesn't put much weight on his back legs. He still curls his tail and sits up right. Sometimes he lays on his back which makes me nervous and I flip him over if he doesn't hiss at me (which is rare). I try to take him outside but I'm worried it stresses him even in his enclosure.

I guess my questions are:

Am I on the right track with the care I'm giving?

Is it MBD, broken bone, or both? I may have a vet that can take him in for an X-ray but I'm waiting to hear back.

Should I give him some sort of brace? I saw someone gave their chameleon a cast made from a straw to help with MBD/broken bone.

Is there a "point of no return"? A time table would be great to help me track his progress.

I'm staying positive and vigilant. I work most days from home so I keep a close eye on him without stressing him out. He's surprisingly well tempered and only hisses when he sees the dropper with his liquid diet...which is perfect because it's easy to give it to him :)

I'm willing to do whatever it takes for my little guy.

Thanks for reading.
 
As posted in your other thread (maybe a moderator can combine these?):

I don't see obvious signs of MBD, but in that second picture it looks like the back half of his body starting around his hind legs is slightly darker. Not sure if that is a fluke of the lighting.

Do you know what caused his injury? Staying and sleeping on the bottom like that is definitely not normal so it seems like something is bothering him. Is his spine straight all the way to the back? If he bruised it maybe he doesn't have full control of the back of his body.

Do you have a reptile/chameleon vet? I am sure someone can recommend a good one if you don't. They really need to specialize in chameleons due to their uniqueness.
 
Everything I've ever heard or read concerning reptiles in general points to a lack of UVB and/or calcium being the cause of MBD. I can't see how it would have happened so suddenly, either. You should have noticed some kind of degradation in his condition over time, even if not drastic.

If your UVB bulb is current (usually 6 months expiration on the coil 5.0's) and he's getting his supplements, this sounds like more of a traumatic injury. Maybe getting crushed or dropped. That xray might be really helpful.

I feel you on trusting someone with your pet and regretting that choice. My female hog island boa got sold to a pet store by a "friend" who was watching her for me... I had to delay picking her up by a week due to car trouble. His explanation? "I can't afford to keep feeding your snake." UGH.
 
MBD can appear to happen suddenly because until it reaches a certain point it may not show up in the limbs. Sometimes a sudden trauma will cause an already weakened bone to break when the bowing/deformities haven't really shown up yet. This being said I really think you need to get him to a vet ASAP because he should not be laying on his side like that.
