EASY Algorithm Trial (Elbow Trauma Assessment Using Sonography in Children and Youth) Diagnostic Accuracy and Safety of Point-of-care Ultrasound as a Screening Tool for Suspected Elbow Fractures in Children Aged 5 to 15 Years: a Multicenter Prospective Cohort Study

This study is looking for children and young people between 5 and 15 years old who have recently hurt their elbow and whose doctor thinks they might have a broken bone.

However, some children won't be able to join. For example, if the elbow injury is part of many injuries at once (like from a major accident), or if the injury happened more than three days ago. Also, if there's a visible bend or twist in the elbow, or if the skin is badly damaged, they can't take part.

It's also important that parents or guardians can understand German, either spoken or written, as this is where the study is being conducted. If your child has already had X-rays of the same elbow injury from another hospital, or if there are problems with their circulation or movement in the injured arm, they won't be suitable for this study.

If your child takes part in this study, they will have a few things happen. First, a doctor will use an ultrasound machine to look at their injured elbow. This is a bit like the scans used during pregnancy, where a gel is put on the skin and a small wand is moved over the area.

After the ultrasound, your child will also have standard X-rays of their elbow. This is to compare the ultrasound results with the usual way of checking for fractures. Researchers will also look at your child's medical notes. If no fracture is found during these initial visits, you will receive a phone call about 6 weeks later to check how your child's elbow has healed. There are no medications involved, and the entire process of the study is focused on gathering information about the diagnostic tools.
