If there is a fracture, it is possible to check whether there was a fracture before by X-ray or CT examination after 6 months. It takes 1~2 years to fully recover from a fracture, and the fracture can be fully recovered through the scab remodeling period (it takes about 1~2 years). The remodeling period allows the newly created bone scab to be remodeled and shaped under constant stress. In the end, there is no trace of the fracture on histology and imaging, so that the previous fracture can be detected by X-ray or CT examination in about 6 months. At this time, the manifestation on X-ray or CT is the formation of bone crust at the fracture site, which can be detected because the bone crust has not finished molding at this time. If the previous fracture is subtle, it may not be obvious on X-ray and can be clearly detected by CT examination. Consult your physician for details.
