What is the Role of Point of Care Ultrasound for Suspected Pulled Elbow in Children?

Children presenting with suspected pulled elbow who have evidence of hook sign (or J-sign) and an absence of elbow effusion on POCUS can be diagnosed with pulled elbow and safely undergo reduction. POCUS can be used following reduction to demonstrate resolution of these signs and confirm its success. Elbow injuries with effusion are likely to have bony injury, meaning that X-ray is required. Additional prospective study of children presenting with elbow injury would be required to accurately determine the effectiveness of POCUS in the diagnosis of pulled elbow.
