My son broke his ankle skateboarding

My 14 year old son broke his ankle while skateboarding, right at the start of the summer.
He was doing a trick he had already mastered. This time, he just happened to land wrong.
It was a major break, and was dislocated too. So, it was quite an adventure.
The paramedics were called, the break was severe enough for them to insist he be transported by ambulance.
The poor kid waited for surgery at Children's Hospital for two days.
(On his birthday no less) in severe pain, on morphine.The dislocation was higher up from the break, they fixed that before surgery.
He was taken to surgery, which took about four hours. He emerged with four metal screws inside the ankle & a metal pin protruding outside. 
They put his leg in a cast and he has gone to see a Pediatrics Orthopedic doctor for X-rays a few times now. 
He’s been pretty bummed out about being stuck in the house and not being able to skateboard.
He was set to get his cast off last month, pending X-ray's. The poor kid, his ankle just was not healed all the way.
Now, his next doctor visit is on the 14th.
He starts high school on the 8th, on a huge campus, with crutches & cast.
Most of the safety tips did not apply, but maybe they will help someone else.
I have a video of him, with the paramedics right after this happened. 
I did not post it because the injury is pretty bad.

Tips for Using a Skateboard

Give your board a safety check each time before you ride.

Always wear safety gear. 
Never ride in the street. 
Obey the city laws. 
Observe traffic and areas where you can and cannot skate. 
Don't skate in crowds of non-skaters. 
Never have more than one person on a skateboard. 
Never hitch a ride from a car, bicycle or other such means. 
Don't take chances; complicated tricks require careful practice and a specially designated area. 
Learn to fall-practice falling on a soft surface or grass.
