What are bilateral bipartite sesamoid bones in a runner?

This episode comes from a question from one of the Doc On The Run YouTube channel viewers who wanted to know about “bilateral bipartite sesamoid bones” and what that really means.  I get these kind of questions all the time, when somebody really wants to know what a term means, and what the implications are for them as a runner. Usually the runner is trying to figure out how to keep running while the sesamoid heals. Sometimes the concern is a sesamoid stress fracture or a condition like sesamoiditis where you start to get pain under the big toe joint.  If you see a doctor, they look at your x-rays, they may tell you, "Oh, you have bilateral bipartite sesamoids."  Today on the Doc On The Run Podcast, we're talking about bilateral bipartite sesamoid bones in a runner.
