Cuboid stress fracture vs. Calcaneocuboid joint arthritis. How can a runner tell the difference?

If you call me and you tell me, I think I have a cuboid stress fracture, the first thing I'd say is...pretty unlikely. 
 
In fact, cuboid stress fractures are less than 1% of all the stress fractures that happen in the foot in athletes. 
 
So they really are very rare. 
 
One thing you can get that's actually much more common is arthritis within the joint. That's also pretty rare, but you can tell the difference.
 
How can a runner tell the difference between a cuboid stress fracture or calcaneocuboid joint arthritis? 
 
Well, that's what we're talking about today on the Doc On The Run podcast.
