Femur Fracture clinical trials at University of California Health

The goal of this prospective observational study is to compare pain control strategies in children with femur fractures. Researchers will compare ultrasound-guided fascia iliaca compartment nerve block to IV pain control alone. The main questions it aims to answer are: - Are ultrasound-guided fascia iliaca compartment nerve blocks as effective as IV pain control in controlling pain? - Do patients who receive an ultrasound-guided fascia iliaca compartment nerve block require less opioid pain medication than those that don't? Participants will be asked to provide pain scores during their Emergency Department stay. Participants parents will be asked to complete a brief survey at the time their child is leaving the Emergency Department.
