title: Orthopedic injuries associated with backyard trampoline use in children.
abstract: BACKGROUND
  Trampolining on an outdoor oval or circular trampoline is a popular activity for children but is associated with a number of orthopedic injuries, especially in children between the ages of 5 and 15 years. In this paper we review the orthopedic injuries in children associated with backyard trampoline use, through our experience with a series of children admitted to the Winnipeg Children's Hospital, the only tertiary care pediatric centre in Manitoba.
  
  
  METHODS
  We reviewed the charts, x-ray films and operative reports for 80 children under 16 years old (mean 9 yr, with 14 [18%] children between 2 and 4 yr) with an orthopedic injury sustained when using a trampoline in the backyard. We noted the mechanism of injury and type and severity of orthopedic injury sustained.
  
  
  RESULTS
  Fifty-two (65%) children were injured on the trampoline mat, and 24 (30%) were injured when they were ejected from the trampoline. Sixty (75%) children sustained a fracture or fracture-dislocation. Forty-eight (80%) orthopedic injuries occurred in the upper extremity. No child died as a result of a trampoline injury.
  
  
  CONCLUSIONS
  The use of the "backyard" trampoline by young children can cause significant orthopedic injury.
