Depends on how large the jump is...
I hit a few this past season on 40ish footers and that combined with some drops with flatter landings gave me a stress fracture in the fibula of my back leg.
Schims hit it though... try to absorb the impact at all costs. I've found that lowering my tail/nose (depending on the trick) so that it hits first helps. The flex of the board sort of allows you to roll into the impact and provides a lot more cushion. But if you land perpendicular to the slope, you're basically fucked.
