Hip Pain in Preschool-Age Children

Abstract

Evidence is lacking on the most common causes of hip pain in children because most data come from cohort studies and include referred patients. Based on these studies, transient synovitis is the most common cause of hip pain in preschool-age children, accounting for more than 80 percent of cases. (Strength of Recommendation [SOR] = B, based on fair-quality cohort studies performed in referred populations). Septic arthritis, Legg-Calvé-Perthes disease, and trauma are important but less common causes of hip pain in this age group. (SOR = B, based on fair- quality cohort studies performed in referred populations).
