Previous year in march I had a terrible accident with my little dirtbike (pitbike). Here you can read the article (in dutch) from then and view some images of the fracture.
Due to a bad landing on the track I smacked hard to the dirt after a jump. My bike landed on my right leg and my leg was broken on several places. After more than a year and a half of pain and side effects, the dokters (specialists) decided to remove all the material out of my leg because now it is strong enough again to wear the weight of my body.

Picture from what they removed: Titanium Nuts and Bolts!
