Bone Growth on Pathogenic Dinosaur Fossils

I'm wondering if healed injuries in dinosaurs may have some correlation with metabolism. Do reptiles heal slower than a bird or mammal when, say, a rib is broken? Theoretically, an endotherm that is ingesting a lot more food than an ectotherm should be able to heal quicker - and show some distinctive isotopic levels or bone growth patterns. Any info on this?
