Hi Dr. O, this ones for you.
Could you tell me exactly what is the "cortical bone?
I think it is the third metacarpal, but not sure. Also what is the general prognosis, in your experience, of a fracture to this bone.
THANKS!

Hello Ike,
Cortical bone is the "outside" or structural part of any bone and characterized by high calcium-phosphate content. This cortical bone surrounds the cancellous bone which is the softer middle where cartilage, blood vessels, and tissues that produce blood cells predominate.

There is no "general fracture" of the cannon bone Ike that can be compared across the board but the prognosis of any long bone fracture depends on
  • how much of the bone has fractured through
  • damage to the surrounding soft tissue especially the blood supply
  • the size and age of the horse

Dr. O,
Yes, of course. That makes sense.
Thanks!
