RedactedNarrative: On 10/22/2016 at about 12:10 hours Subject#1 was wake boarding behind a 1989 Sanger Ski Boat Arizona registration xxxxxx.  The boat was operated by the Owner#1. The boat was going towards the main bay near the "no ski" buoys on Canyon Lake. Passenger#1 was acting as the observer and there was other passenger in the boat: Passenger#2. 
  
  Subject#1 attempted to do a flip from one side of the wake to the other. He went upside down and "crashed" when he came back around. Subject#1 said the crash broke his right femur. They got Subject#1 out of the water and into the boat and brought him to the Canyon Lake aid station. 
  
  I examined Subject#1's right femur and saw it was swollen and he said it very painful.
  
  Owner#1 told me he was "sober" and everyone told me they had not been drinking. Owner#1 said he was traveling about 24 mph. 
  
  Air Evc arrived and Subject#1 was transported to Scottsdale Osborn hospital. 
  
  Nothing further.
