To determine whether there is a bone fracture in the heel, the diagnosis is mainly based on whether the patient has a history of trauma, whether there are clinical symptoms and signs, and with some auxiliary examinations. For example, when a patient suffers from external force, fall, smash, traffic accident, causing significant local swelling, pain, intense local pain on pressure, and a large amount of subcutaneous petechiae, and the patient is afraid to walk or move on the ground, a local plain X-ray and CT examination can be performed to determine whether there is a heel fracture, so that the corresponding treatment plan can be determined. The treatment plan can be determined accordingly. If the examination shows that the heel fracture is well aligned and aligned, the patient can be treated conservatively by strict external fixation in a cast for about one and a half months before the external fixation can be removed and functional exercises of ankle flexion and extension can be performed.
