[Anterior cruciate lesions and the protective components of ski bindings].

Serious internal injuries of the knee make up today for the main share of alpine skiing casualties. As well the frequency of such mishaps, as the type of injury and the analysis of how the events happen to unfold, make obvious the requirement for a better protection of the knee joint, and more specifically, of the anterior cruciate ligament. The main role in this regard falls to the ski binding systems. To this end, adding a back fall release trigger, in introducing a vertical elasticity component, may be adequate to avoid the peak strength impulse which acts on the anterior cruciate ligament during an unprotected fall backwards.
