Why Stress Fracture Grading is BS for Runners

I just had an interesting call with an elite runner, who's a high school cross country runner.  He developed a tibial stress fracture, or stress reaction.  But he thought it was shin splints. When I looked at it with ultrasound, I saw some stuff that made me really worried about it. So, I got an MRI to confirm.  The first question he had was, what's the grade? Grading scales cause confusion. Today on the Doc On The Run Podcast we're talking about why stress fracture grading is BS for runners.
