Abstract
Ultrasonography has begun to be applied to the examination of fractures in recent years owing to its safety, noninvasiveness, portability, and high sensitivity. The subcutaneous soft tissue of children is thinner than that of adults, children's bones have a high level of elasticity and a low level of brittleness, and the pediatric fractures heal quickly and produce more callus, therefore ultrasonography is a more suitable examination in pediatric bone fractures. In this paper, we intend to review the mechanism, performance, and examination effect of ultrasound examination in bone fractures, analyze the advantages and disadvantages between ultrasound imaging and X-ray imaging, and further propose an outlook for the application of ultrasound technology in pediatric bone fractures.
