Disruptions in the continuity and integrity of the fracture line at the bony site are primarily observed on radiographs. Fracture lines will be evident on radiographs after a fracture. Fracture lines usually appear as highlighted lines on an x-ray. When looking at fracture lines on an x-ray, it is best to do so under an even light source so that the details of the bone damage can be clearly distinguished on the x-ray. In conjunction with the patient’s site of pain, the condition of the bones in the corresponding part of the radiograph can be viewed. Discontinuities, interruptions, and angulation of the fracture line may be detected, or there may be an appearance of misalignment of the bones. It is also necessary to carefully observe the trabecular alignment of the bone for continuity, limited density increase and other manifestations in order to find some subtle fractures. X-rays are best viewed under the guidance of a doctor to comprehensively determine the fracture and provide timely targeted treatment.
