Seven children (aged 2-5 years) sustained fractures of the proximal tibial metaphysis while jumping on a trampoline with a heavier child or adult. Most impaction fractures were transverse and neither angulated nor displaced. None of the children developed permanent disability or impairment. Parents and physicians should be aware of the possible danger to small children while tandem jumping on a trampoline with a heavier partner.

Activities like ball bouncing and trampoline jumping showcase the human ability to intuitively tune to system dynamics and excite motions that the system prefers intrinsically. This human sensitivity to resonance has been experimentally supported for interactions with simple linear systems but remains a challenge to validate in more complex scenarios where nonlinear dynamics cannot be predicted analytically. However, it has been found that many nonlinear systems exhibit periodic orbits similar to the eigenmodes of linear systems.

Study Design: The authors designed a 20-year cross-sectional study using the National Electronic Injury Surveillance System (NEISS) database.
Objective: The purpose of the study is to determine the risk factors for hospital admission among individuals who suffer head and neck injuries secondary to trampoline use.
Methods: The primary predictor variables were a set of heterogenous variables that were categorized into the forementioned study variable groups (patient characteristics and injury characteristics).
