Ok, so i have got the vet report for Tyers investigations.
This is roughly what it says:
''X rays show some sidebone on lateral aspect of both feet, not particularly active looking. very flat pedal bones v small oestophyte at dorsal aspect of rf pastern.''
I'll give this a try (good revision/ learning exercise for me)
Your horse has sidebones on the outside of both front feet. Sidebones are basically the mineralisation of cartilage plates that sit across the coffin joint. Horses are particularly annoying animals in that they immediately form new bone in response to any trauma or injury. not active will mean that the cartilage isn't ossifying (turning into bone) actively at the moment. Horses may be lame during the formation of sidebones as the area does become inflamed and painful, but they are of very little clinical significance once formed and tend not to cause any problems.
They haven't yet told us the significance if any of flat pedal bones. I don't know whether this is referring to the general angle of the bone or the shape so wont comment. Could be shock absorption problems or even just a general observation (vets seem to like making these)
The small osteophyte - dorsal aspect rf - dorsal does usually mean 'back' but when talking about anything below the knee in the horse the dorsal side refers to what we would call the front of the limb, the back is known as the palmar aspect. rf I'm assuming means right front. So he has a small bony bump on the right pastern (crap term, doesn't really help locate exact location. Which pastern, pastern joint?) on the front of his leg. If this is in a joint area (most likely place for extra bone to form) it could potentially cause problems. Only as it is forming - again inflammation and pain so a possible cause for lameness unless the bony bump interferes with the action of the joint in which case it could lead to Degeneratibve joint disease (DJD or arthritis)
However on the whole it doesn't look like a bad prognosis. Looks like concussion may have to be limited ie no fast work on hard surfaces for the time being.
ps I am not an expert, simply a first year vet student trying to revise anatomy. decided that trying to put it into practice on newrider is a better revision technique than simply rote learning
