Which bone had spurs removed after Biles's 2013 World all-around win?

After winning the 2013 World all-around title, Biles had bone spurs removed from her right tibia.

The surgery followed her breakthrough World Championships in Antwerp, where she won the all-around at age 16. Bone spurs are abnormal bony growths that can cause pain or irritation, particularly under the repeated impact and extension demands of elite gymnastics. The procedure sidelined Biles for about three weeks.

The right tibia is the shinbone on the right side of the lower leg. It is not the fibula, the thinner bone alongside it, and it is not the femur, which is the thighbone. Those anatomical alternatives are common quiz traps because all are major leg bones.

Biles returned to competition and continued building one of gymnastics' most dominant careers. Her 2013 season already included U.S. and World all-around titles, and the surgery did not prevent her from becoming a repeat world champion in 2014.
