With this term we mean the concretions reportable at different structural levels.
Usually, with the term calcification we refer to the “free” concretions: namely, to those calcifications that don’t have any relations with the osseous structures. On the contrary, the exostosis is a concretion that, relating directly to the osseous structure, changes its profile.
Calcifications and exostosis are a frequent cause of inflammatory sports pathology, and especially of the post traumatic ones.
