Mechanisms of injury are categorized as follows:
1. Low-energy trauma (~100 foot-pounds of energy)
- Torsional injuries
- Fall from standing
II. Moderate-energy trauma (~300 – 500 foot-pounds of energy)
- Skiing injury
- Bicycling injury
III. High-energy trauma (greater than 2000 foot-pounds of energy)
- Motor vehicle accident
- Fall from height
Incidence rate for the fracture types under the Gustilo-Anderson Classification System are as follows:
•Most common cause of open fractures includes crash injuries, falls, and road traffic accidents.
•Type III open fractures are 7 times more likely to develop an infection
•Type IIIC fractures are 25-90% likely to need amputation.
