Way back about 1952, when I was 12 years old,was showing off by dismounting my bike, running along side it for a ways and then hopping back on it. Unfortunately, my foot slipped off the pedal and went into the spokes and that was about the same as power brakes nowadays. Bike came to a quick and complete stop and I started falling over backwards but landed very hard on my right elbow. Shortly afterwards noticed that it was getting difficult to bend and finally couldn't stand the pain any longer. Fessed up to mom and off to the doctors. Seems like I damaged it enough to start some kind of growth or something right in the joint where it flexed. Spent the rest of the summer and into the fall walking to the hospital three times a week for therapy. They wrapped it in hot warm towels, then made me put it in a whirlpool that was about scalding for a while. Lastly, I had to start lifting small weighgts via a pully system attached to a wall and do it for a few minutes and gradually longer till I recevered full use of the elbow. No fancy surgery or stuff back then for dumb little boys showing off! As others have said, don't overdue using the elbow till your therapy is completed.
