Elbow, and not electric
Meh, I injured myself the old school way: kick scooter (i.e. I was the engine), hit a kerb with my front wheel, flew like Superman, did a screw through the air, landed on my left elbow (dislocation and terrible triad injury). Helmet wouldn't have helped me :)
Cause: good old speed (the m/s kind, not the kind mentioned in the article) and lack of judgement
I was seen by an elbow specialist and my healing is astounding after 9 months. Very little loss of range of movement.
