Yes. My older sister broke her arm when she was about 2 (i think? i wasn't born until she was 7). Her arm was broken in 6 places and never healed to become a normal human arm, so she now has 6 extra bones totaling 212 bones. I heard about this story recently and i have also become interested in humans with more than the average amount of bones, but i can't find any results.
