Nick’s doctor tells him that his injury is a rare one. “It’s very difficult to break the longest and strongest bone in the human body,” she says. What bone did Nick break?

The femur, or thigh bone, is the longest and strongest bone in the human body. Since Nick’s doctor describes the injury that way, he broke the femur. The tibia is also a large, weight-bearing bone, but it is not the longest and strongest.
