The fracture is determined by the history, symptoms, signs, and ancillary examinations as follows: 1. From the medical history, most fractures have a history of trauma, fatigue, or strenuous exercise. 2. 4. Auxiliary examinations, such as X-ray, CT, or MRI, can clearly show the presence of fracture lines, as well as the degree of displacement and comminution of the fracture. In short, to determine whether you have a fracture, you have to judge by medical history, symptoms, signs, and auxiliary examinations.
