Conclusion: Swings at school are the most common mechanism of injury for TBIs, and the seasonal
data would suggest that increased supervision of children using swings during school hours might
reduce the occurrence of TBIs. Monkey bars are the most common cause of fracture, and fracture is the
most common cause of admission. Prevention strategies to reduce the number of fractures should be
directed at monkey bar equipment and landing surfaces. The trend in playground equipment injury also
indicates that monkey bars are problematic because the number of injuries per year per capita owing to
monkey bars is stable, whereas those from swings and slides is decreasing.
