BACKGROUND The recreational use of trampolines is an increasingly popular activity among children and adolescents. Several studies reported about radiological findings in trampoline related injuries in children. The following publication presents our experience with MRI for detection of trampoline injuries in children. METHODS 20 children (mean 9.2 years, range: 4-15 years) who had undergone ...

In the high-speed collision between a baseball and bat, most of the initial center-of-mass kinetic energy is converted into compressional energy in the ball, and about 75% of that energy is dissipated. Some of the energy is stored in vibrational modes of the bat, particularly in the so-called “hoop modes”, the most important of which is a radial deformation with a quadrupole azimuthal dependenc...

We reviewed the records of children referred to our hospital between April and September 2005 who had been injured whilst trampolining. Of 88 such children there were 33 boys and 55 girls with a mean age of 8 years 6 months (2 years 4 months to 15 years 9 months). Most of the injuries (53; 60%) occurred when bouncing and 34 (39%) were secondary to falls from the trampoline. The cause of injury ...
