Radial Head Subluxation: Factors Associated with Its Recurrence and Radiographic Evaluation in a Tertiary Pediatric Emergency Department.

Background: Radial head subluxation (RHS) is a common complaint seen in the pediatric emergency department in children ages 6 months to 4 years. Classically, injury occurs due to axial traction on the arm, but this mechanism is not universal. Some patients will have recurrent RHS; some may undergo x-ray (XR) evaluation for alternative diagnosis.
