ballerinas feet
Ballet dancers may develop sesamoiditis.
Sesamoid bones are unique because they are the only bones in the body that are not connected to other bones via joints. Instead, they are connected to other bones by tendons, or they are embedded in muscles in the body.

Examples of sesamoid bones in the body include the kneecap and two small bones in the foot, which are roughly the size of a corn kernel.

These foot bones are located underneath the foot, one on the outer side of the foot and the other near the middle of the foot. They are embedded in the tendon that helps move the big toe.
