Objectives: After studying the article entitled “Sonographic Evaluation of Fractures in Children,” you will be able to:
Explain the benefits and challenges for using sonography to diagnose pediatric bone fractures in comparison to other imaging technologies
Describe the evidence for sonography’s diagnostic specificity and sensitivity for bone fractures in various regions of the body
Describe the evidence for sonography’s diagnostic specificity and sensitivity for bone fractures in various regions of the body
Which type of bones have the most research evidence demonstrating high sensitivity and specificity of sonography for diagnosing fractures? Arm and hand bones Chest and back bones Face and skull bones Leg and foot bones
What is an advantage that sonography has over other imaging techniques in the diagnosis of pediatric bone fractures? Sonography clearly shows intraosseous abnormalities and open bone fractures Sonography is useful for differentiating the cause of pain in individuals with polytrauma Sonography of bones is easy and is not dependent on the experience level of the user Sonography permits evaluation of the cortex of long bones in multiple planes
For best visualization of cortical disruption in a bone fracture, the transducer should be positioned 45 degrees to the fracture line Coronal to the fracture line Orthogonal to the fracture line Parallel to the fracture line
What best describes the normal sonographic appearance of an unossified epiphysis in pediatric bones? Anechoic space between two hyperechoic continuous lines Continuous echogenic line around the end of the bone Homogeneous hypoechoic pattern with scattered hyperechoic signals Hyperechoic border with anechoic shadowing in the far field along the length of the bone
A common indicator of a bone fracture is two parallel hyperechoic reflections along the surface of a long bone. This image signal is known as a Cortical deviation Double-line sign Fracture step-off Hemorrhagic signal
