Recently, it has been reported on the basis of statistics compiled by Japan School Safety Association that the number of fractural accidents of children became larger progressively. On the contrary, some are opposed to this view. 1, 330 children with fracture treated at National Senboku Hospital and New Senri Hospital for the last ten years have been statistically investigated with respect to the causes and the mechanisms. Especially, a fracture in the forearm accounting for 27.9% of all the cases has been examined on its site and type. Moreover, investigation has been made to 367 adult patients with fractures of forearm.
Consequently, there was no tendency to year-course increase in fractural events of children. Fracture occurred most frequently, in 27.9%, at the forearm and was due to a fall or turnover in 62.0%. These findings did not markedly differ from those of previous reports. In children, bones of the forearm were often fractured at the distal diaphysis (53.0%) . The bones were broken by turnover or fall in 81.9%. The state of the extremities when the event occurred could not be analysed clearly. There was no marked difference, again, between our results and previous reports. It is suggested, therefore, that statistical data obtained from hospitals are insufficient to discuss whether or not fractural events of children have increased, and that various factors related to these fractures, especially the protective buffer effect, should be clarified.
