The trampoline is a popular source of recreational and competitive sport. However, little is documented about the dangers associated with its use particularly in the paediatric population. We reviewed paediatric patients referred to our service from April to September 2005 inclusively, having been injured on a trampoline. This unit services a catchment area of approximately 400,000 patients. Eighty-eight patients were assessed (mean age: 8 years 6 months). There were 33 males and 55 females. Most injuries (53/88) occurred while bouncing on the trampoline, while 34 were secondary to falls off the trampoline. The injured child was supervised in only 40% cases. In 31 cases, the injury was attributable to the presence of others on the trampoline. Thirty-six children required surgery. Fracturesof the upper extremities occurred in 70% of cases. Injuries related to the recreational use of trampolines are an important and significant cause of paediatric injury. These results strongly suggest that there is a clear need for guidelines.
