While effective, X-rays require transporting patients to a radiology suite, involve exposure to ionizing radiation, and can contribute to longer emergency room wait times. POCUS is a portable, radiation-free imaging tool that physicians perform directly at the patient's bedside. The investigators hypothesize that POCUS can accurately identify or rule out long bone fractures when compared to standard X-rays, and that its use will reduce the time required to make clinical decisions.\n\nThis is a multicenter, prospective observational study. Participants arriving at the emergency department with a suspected long bone fracture will undergo a bedside ultrasound examination performed by a trained emergency physician. Following the ultrasound, all participants will receive standard-of-care X-ray imaging.\n\nResearchers will compare the initial POCUS findings to the final X-ray results (the reference standard) to determine the sensitivity and specificity of the ultrasound. Additionally, the study will measure operational timelines-including time to diagnosis, time to treatment decision, and total length of stay in the emergency department-to assess the impact of POCUS on hospital workflow and patient care efficiency.",[24,25],"Bone Fractures","Long Bone Fracture",[27,28,29,30,31],"POCUS","Ultrassound","Fractures","Bones","POCUS BONES BR","NOT_YET_RECRUITING","2026-07-21",{"date":35,"type":36},"2026-07-27","ACTUAL",{"date":38,"type":20},"2026-10-19",{"date":40,"type":20},"2027-11-20",{"name":42,"class":43},"University of Sao Paulo","OTHER"]
