With a chameleon who has MBD this is quite important:
Do NOT attempt to manipulate any of his/her limbs.
To quote from Dr Wissman of exoticpetvet.net ,"Handling MBD patients should be kept to a minimum to prevent additional damage to the skeletal system." and on Adcham, Dr Kramer states,"Be very careful handling patients with MBD as their bones are very fragile and subject to further injury if mishandled."
Obviously, MBD chams have extremely fragile bones and trying to help his leg will be
much more likely to do harm than good.
The reason that animals with MBD don't get their broken bones splinted is that the same bone is very likely to break above and below the splint

His hip may not actually be out of place--it may be a bone deformity resulting from MBD or the beginnings of hind limb paralysis--also of MBD origin.
If crickets have been the only food for your cham, then MBD is not a surprising result. The ratio of calcium to phosphorus in crickets (and mealworms) is the opposite of what they need. Gutloading and dusting with Calcium without D3 (most often) do make them suitable food for chams.
There should be a variety of insects in your cham's diet: Silkworms, butterworms, Phoenix worms, Dubia roaches and superworms are good foods for your Veiled.
I don't know the details of your setup, but hope that you do have a Reptisun 5.0 UVB light , calcium powder without D3, another calcium with D3 and vitamin powder.
Here's an excellent site with plenty of details on care of your Veiled cham:

Do take note of the recommended cage size, for when your chameleon is better.

Hopefully, this info will help you to get Yoda recovering more quickly than the seemingly vague advice that you mentioned.
Not all vets are familiar enough with chameleons to treat them properly.
