Examination methods of rib fracture: 1. Local pressure method. Local if the fracture displacement is more obvious, you can feel the local deformity, the feeling of bone rubbing. However, if the fracture is localized and the displacement is not obvious, only the local swelling and pressure pain can be felt. 2, thoracic squeeze sign, the operator usually uses the palms of both hands and places them at the location of the sternum in the anterior thoracic region, behind the thoracic vertebrae in the back, and then squeezes the thorax in the middle. If there is a painful episode at the location of the rib injury when squeezing, or if the pain is aggravated on top of the original pain, this is called a positive thoracic squeeze sign and is a highly suspicious technique for rib fracture. 3, X-ray examination, usually check the X-ray to rule out the presence of rib fracture, you must do the orthogonal and double oblique position of the chest to be able to see clearly. 4, some very subtle crack fractures, even the X-ray can not If you can’t rule out the fracture, you can use chest CT, preferably a 3D CT of the chest followed by 3D bone reconstruction, which can basically confirm the diagnosis.
