case 009 - The Fracture That Wasn't on the X-Ray

A deep midfoot ache. Weeks of it. A normal X-ray. A green light to keep training. And then — a complete fracture.

The navicular stress fracture is running medicine's most deceptive case. The bone sits at the apex of the medial arch, absorbs enormous compressive force at push-off, and carries a blood supply too poor to tolerate a missed diagnosis. Get it wrong and a stress reaction becomes a fracture. Get that wrong and you're in surgery.

In this episode, we work through the five suspects — athlete profile, foot geometry, training errors, RED-S, and the early warning signal that runners keep training through. We cover the N-spot, the hop test, and why a normal X-ray is not reassurance. We explain why CT and MRI are non-negotiable, why immediate removal from running is the only appropriate response to clinical suspicion, and how fracture grade determines everything that follows.

This one's for every runner who was told their X-ray was fine and went back to training anyway.
