We have been ultrasounding hips for a while now. We know this modality is accurate for finding effusions. This can really help in cases of suspected septic arthritis. Unlike patients with this disease, this study takes multiple steps forward. First it asks the question - "Does point-of-care ultrasound (POCUS) in the emergency department lead to a faster diagnosis?". Then it goes further by trying to determine whether or not POCUS can lead to earlier treatment as well. Fascinating results from a really hip study!
