To determine whether a patient has a fracture, we must first look at the history of trauma, but also look at the patient’s symptoms, the fracture site will usually be swollen and painful, you can also judge from the physical signs, the fracture will lead to loss of function, there may also be deformities of the limb, appear in these symptoms and then combined with X-rays and other tests to confirm the diagnosis of fracture. Fracture to see whether the patient has a fracture, from the following aspects to determine. The first one is to see if there is a history of injury. Fractures usually have a history of external injury. You lie still, even if the bone is destroyed, the bone is loose, the fracture has been completely destroyed, lying motionless, how can it be fractured? There must be an external violence. Of course, like young people, external violence can be very large. The second look at the symptoms. After the fracture, the fracture site will be swollen, the swelling is very strong, the patient is in great pain, you let him move, the fracture, the patient’s own limbs can not move, this is the symptom. The third one is judged by the physical signs. When we touch the fracture site, we will feel the bone stubble touching back and forth, we feel the bone rubbing sound, originally the bone is a bone stick, it will not move when you move it, but after the bone is broken, there is an abnormal activity, regardless of the two sections, there is an abnormal activity. When you ask someone to move it, it can’t move by itself and its function is lost. After the fracture, the bones are not in their normal position, and some limb deformities may occur, such as abnormal deformities in the arms and legs, regardless of rotation and twisting after the break. If these manifestations occur, then we highly suspect a fracture, and we need to take a film to confirm whether it is a fracture, which part is fractured, what type is it, and how to treat it, but there are some tiny fractures, some small gaps may not be judged by ordinary light film, then some need to further investigate a CT, CT and then not to do a three-dimensional reconstruction, generally for the This fracture can be diagnosed.
