Welcome Cody, sorry to hear about your accident, but its a good reminder for us all to be careful whenever we are doing dangerous things. And yes ladder falls are way too common and dangerous.
I had an employee on a roof. I went to the front of the house and heard commotion and a scream. Went out back to see the fellow laying on the ground in pain. He tried to climb down the ladder with out the help of someone footing it (which has always been our policy) and the bottom slipped out. Like you, he fell about 10ft. landed squarely on his heel breaking it in half. He was laid up for almost a year exactly.
I hope your recovery is much better, I look forward to the progress on your car.
