The forearm (radius and/or ulna) fractures are the most common fractures of childhood. One third of all fractures are radial fractures in the distal part. The fall on the extended arm is the main mechanism of injury. The diagnosis is based on anamnesis, physical status and x-ray image. The treatment procedure mostly consists of fracture repositioning and arm immobilization. The high incidence, and the possible poor outcomes of treatment, justifies the questioning of preventative measures in the occurrence of these injuries in children. For successful prevention, it is necessary to know the places and ways of the fracturing. The aim of this study is to investigate the sites and ways of the fracturing the forearm in the children living in Zagreb. In a tested analysis 395 children with forearm bone fracture were treated (hospital and outpatient) at UHC - Zagreb in the period from January 1st 2014 to October 19th 2017. The examined group consisted of 265 boys (67.1%) and 130 girls (32.9%). The average age was 9.1 years. Girls were on average younger than boys; approximately 16 months. The majority of children was 5-9 years old, 175 (44.3%) of them. There were 104 (26%) children with isolated distal part of the radius, 104 (26%) with distal parts of both forearm and the 96 (23.6%) children with diaphyseal fractures. The leading cause of fractures in our children's group is falling. Thus in 94 (23.1%) the fall was at ground level, and in 55 (13.8%) was low height fall. Activities during which fractures usually occurred were recreation and sports, 274 children (68.7%). Of this, there were 69 fractures (26.2%) while playing in the park, 54 (19.7%) while riding bicycles and 46 (16.8%) while playing football. Out of 69 children who had had a forearm fracture on the playground or in the park, 39 children (56.5%) experienced the fall in the park play; including swings, slides, and trampoline. Boys fall more often than girls, almost three times more in the ground level, and twice time more from small height. Girls are more likely to get injured by a fall from roller-skates. On average, hospital care in our group of children lasted for 2.8 days. The biggest occurrence is during spring, then during summer. Based on the results of this research, boys are more likely to be threatened with such injuries, and the dominant mode of injury is falling. Mostly, the patients are children of pre-school and early school age. Community should focus on those children during their recreational and sporting activities (cycling and football). Children's playgrounds and parks are the most common places of the forearm fractures in children.
