As a reptile keeper and reptile rescue I have had broken bones in animals. The way how reptiles heal fractures is different from mammals. The first phase the animal is restricted in its movement. In nature, they would find a hiding spot. Reptiles cam go a long time without eating. After a while, usually ten days to two weeks, a callous will form around the fracture, made from fibrous tissue as a natural cast while the bone inside heals. This can look like a huge swelling but it's part of the process. Once that has occurred, the animal can move nearly normal again. And as to why this Dino had fractures mostly of the arms is again easily explained if you just observe behaviors of living reptiles. For instance green iguanas are quite social but also very quarrelsome, especially during breeding season. Two battling males will usually attack each other around the heads and forelegs. Green iguanas also do the "death roll" which can tear off the limbs of another. Seriously, just watch living reptiles and birds and you will find explanations for a lot of the questions. Also, why are carnivores always depicted as screaming or bellowing? That would warn all the other animals and make hunting very difficult.

The ones in the movie had the dna of other animals to fill in the gaps. So of course they're gonna look different.
