I've fed raw meaty bones for more than 20 years. It doesn't seem to weaken pasterns or feet - if anything, the feet and pasterns get strengthening exercise from holding the bones while the dog eats. Dogs with longer pasterns seem to take longer to come up on them.
It is important to feed the meat with the bone. That way they get the balanced minerals from the bone. Feeding calcium without the correct balance of phosphorus and magnesium will lead to joint problems. So, if the dog is fed the raw meat without the accompanying bones small enough to chew and digest (or sufficient ground sterilized bonemeal - not the stuff that goes on the garden), they will be worse off than if they are just fed a good kibble.
I note that others have had problems with impaction (and vets would see these, when they occur, so this would influence their views). The meaty bones that I feed are always raw and from small or young animals and a variety of sources: chicken, lamb, veal, pork. Once or twice a week they get sardines, yoghurt & an egg. Each day, they get a spoonful of oil (cod liver, olive or sunflower) and kelp powder. The oil may act as a lubricant because I have never had a dog with a bowel impaction (or maybe I've just been lucky).
ETA: I've fed puppies from weaning on this diet with no problems. It is important to keep puppies from becoming overweight - too much weight will flatten feet and bend pasterns!
