BoneCrusher is a user-driven database of injuries to paddlers that result from impacts while on the river, with a goal of providing evidence of the effects of impacts on long-term paddler health.

Enter as many incidents as you know of. Enter historical data for insight into the debilitation results. The data entry is simple and quick. Please share the data entry form with friends, clubs, and associations. We need THOUSANDS of entries before we can move from the anecdotal to the statistical realm.
