How do you recognize bone callus on x-ray film?

Bone callus on an X-ray film appears as an area of increased radiopacity (whiteness) around a fracture site, indicating healing. It typically develops within a few weeks post-injury and may present as a smooth, well-defined outline surrounding the fracture. The callus may be more prominent as the healing process progresses, eventually becoming less visible as the bone remodels. Radiologists look for these changes in the context of the fracture's age and the patient's clinical history.
