Horse has sidebone. Not possible to say if active or not based on these rads. Medial/lateral balance is crucial as well as eased breakover. Horse may still be intermittently lame,especially on uneven ground.
Pedal osteitis and articular ringbone, as well as sole depth, cannot be determined by these rads. Nonarticular ringbone is present however.
Determining joint spacing on a rad over the net is a joke. If your not there when the rad is taken, then you have no idea how the shot was set up or how the horse was standing at the time it was taken.
The "floating" spot could easily be crap stuck in the whiteline/bar area that wasn't properly cleaned out.
