The most important basis for determining a fracture is by taking X-rays or doing CT examinations. However, in the case of more serious fractures, the presence of a fracture can be judged by physical examination, for example, if there is obvious swelling and deformity at the fracture site, accompanied by abnormal movement and a sense of friction or a sound of friction between bones can be felt. However, a minor fracture is only manifested as swelling and pain at the fracture site because there is no obvious displacement, and in this case, an X-ray or CT is required to determine accurately. Therefore, the most important basis to determine the fracture is to go to the hospital and take an X-ray or CT for clear diagnosis and treatment to avoid delaying the condition.
