Abstract：Objective To investigate the epidemiological features of hip fractures in children, and to provide scientific basis for researches of prevention strategy. Methods Clinical data of 204 children with hip fractures treated in four hospitals of Fujian Province from January 2010 to December 2012, were collected and analyzed retrospectively. The patients'gender, age, injured factors and sites, types of classification were recorded and statistically analyzed. Results There were 110 males (53.9%) and 94 females (46.1%) with the average age of (9.5 ± 3.8) years old, and the incidence of fracture in children aged 10 to 15 years old was the highest (53%, 108/204). The difference of ratio of male and female among different age groups had no statistical significance (χ2 =5.514, P = 0.238). Total of 122 fractures (59.8%) affected the left side, while 82 (40.2%) the right side. There was statistical difference of ratio of sides among different age groups (χ2 = 21.987,P = 0.000), especially for children aged 4 to 6 years old. Summer and autumn were major high-risk seasons (65.2%, 133/204), and the main injured factors were falls (44.1%, 90/204) and motor vehicle collision (35.3%, 72/204). As for Delbet classification, typeⅠwas the least common fracture (3.4%, 7/204), and typeⅡwas the most common (45.1%. 92/204). Conclusions In Fujian area, high-risk age of hip fractures in children is 10-15 years old, left side is the common injured side (especially for 4-6 years old), the incidence is high in summer and autumn, and type Ⅱ is the most frequent fracture type according to Delbet classification.
