About this trial
The goal of this observational study is to learn about the safety and accuracy of ultrasound as a screening tool to detect broken bones (fractures) in the elbow area in children and youth aged 5 to 15 years. The main question it aims to answer is:
\- Can ultrasound reliably show that there is a fracture in the elbow area after an accident?
Participants will:
* Have an ultrasound of their elbow to look for fluid in the joint. * Have standard X-rays of their elbow to check if there is a fracture. * Have their medical records checked and answer a phone call 6 weeks later to see how their elbow has healed (only if no fracture was found during the first visit).
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
children and adolescents aged 5-15 years with anamnestic and clinically justified need for the exclusion of a fracture after elbow trauma
Disqualifiers
elbow trauma as part of a polytrauma,
parents' insufficient German language skills (spoken or written),
trauma more than 72 hours ago,
presentation at the emergency room with current, post-traumatic external X-ray images of the affected elbow joint from another clinic or practice,
Trial population
All children and adolescents who present to the emergency departments of the participating hospitals with elbow pain following an accident will be screened for inclusion in the study during the study period until the statistically determined required number of cases has been reached.

Trial outcomes
Primary outcomes
Sensitivity of sonographic joint effusion
Sensitivity of sonographic joint effusion examination following a standardized procedure and uniform training of the physicians performing the examination in the detection of radiologically confirmed elbow fractures, as assessed by blinded experts.
Secondary outcomes
Time required for ultrasound examination
The total time for performing and evaluating the ultrasound examination is measured.
The additional time patients spend in the emergency room due to X-ray examinations
The time that patients and their relatives spend additionally in the emergency room due to X-ray imaging is measured. The time at which the family leaves the treatment room after the ultrasound is noted. Then the time at which the family re-enters the treatment room after the X-ray is performed is noted. The difference is the additional time patients spend in the emergency room due to X-ray imaging.
Radiation dose from X-ray imaging (dose area product)
The radiation dose of the initial radiological imaging (dose area product) is recorded.
The initial assessment of the X-ray images by the attending physician in the emergency department
The exact fracture type determined by the attending physician in the emergency department.
Other outcomes
Potential confounders of the primary outcome
Potential confounders of the patients include age, sex assigned at birth, gender identity, pre-existing conditions, location of the accident (in daycare/school or outside of these settings), accident mechanism, swelling of the affected elbow, hematoma of the affected elbow, other fractures caused by the same trauma, and the time interval since the trauma. Potential confounders of the attending physician in the emergency room, who is performing the sonography include previous experience with ultrasound imaging of fractures, the physician's area of expertise, and level of training.
