Abstract

We present three cases of fracture of the proximal tibia in young children who were jumping on a trampoline. The typical radiological findings and the underlying mechanism of trauma are discussed.

The key radiological features are: a transverse hairline fracture of the upper tibia often accompanied by a buckle fracture of the lateral or medial tibial cortex, buckling of the anterior upper tibial cortex and anterior tilting of the
epiphyseal plate. 

New types of injuries related to specific recreational activities are recognized. It is often helpful to associate a typical injury with a particular activity. Trampoline related injuries have increased dramatically over the last years. The
most common lesions are fractures and ligamentous injuries, in particular a transverse fracture of the proximal tibia. However the radiological findings can be very subtle and easily overlooked. It is therefore important to be aware of
the typical history and radiological findings.
