How does natural bone remodeling differ from acute fracture healing in terms of surface appearance?

Explanation:
Natural bone remodeling reshapes the outer surface gradually, with resorption and new bone deposition smoothing the cortex into a continuous, even surface. In contrast, acute fracture healing creates a periosteal and endosteal callus that bridges the fracture, producing a rough, irregular surface around the fracture site. Over time, remodeling can smooth this area again as the callus is resorbed, but during the healing phase the surface contrast is clear: smooth surfaces from remodeling versus a bridging, rough surface from callus formation.
