Not I. Using your hands is supposed to transmit the shock to the clavicle and cause breaks. But is that worse than landing on the edge of the clavicle as you surely must without your hands? I have been using my hands for 34 years through at least 20 falls. The only time I broke my clavicle was when I hit it on the ground anyway. Anecdotal? Sure. But at least that is my experience.
