In long bones, diagrams of haematoma --> callus formation --> callus development --> remodelling have been circulating all over the internet. But since skull is not a long bone, it skips the callus formation stage ( https://www.sciencedirect.com/science/article/pii/B0123693993002044 ).
Is there any authoritative text or review that gives a comprehensive description on how skull fractures heal (i.e. depressive or linear), along with some biochemical/molecular mechanisms?
Thank you.
