Screening for heel fractures begins with a discussion of the circumstances of your injury—From how high up did you fall? How fast were you going during the car crash?—your symptoms and medical history, including any medications you are taking and any medical conditions you may have. After that, your doctor will look for other areas where the skin is punctured or damaged and assess whether your nerves are properly functioning and there is sufficient blood flow to the heel.
Imaging tests are then used to confirm a heel fracture diagnosis. The most common test is an x-ray, which is especially useful in showing fractures, although a CT scan may also be used to assess the severity of the fracture and help your doctor develop a treatment plan.
