I would forward the findings to the best Stateside lameness vet I could find that has evaluated radiographs and reports from Europe before. Include the horse’s history, your projected use, and resale possiblity.
A good friend imported a young barely backed beautiful Warmblood last century, early 1990’s. She did not have X-rays done because she thought it was a waste of $$$. Note this was years before the age of digital xrays.
Anyway, horse ended up being diagnosed with severe Navicular disease soon after being ridden regularly. Think he was four or five years old. Stellar conformation. Just stunning. Sweet big horse. Required nerve block surgery to stay comfortable. You never know I guess?
Horses are a crap shoot.
Second getting an opinion from a reputable vet. I’ve used Virginia Equine Imaging (they do remote review of x-rays) and they’re pretty candid (i.e. buy/not buy recommendation) and in my case helped to dodge a bullet - in hoof conformation specifically. I know a couple of others who wouldn’t buy a horse without one of their vet’s approval. It’s a bit pricey for a short one-page long review (I think ~$400?), but if you’ve invested in a full set of x-rays and the horse is otherwise fine and sound, I’d just do it for my own peace of mind.
That’s kind of my list, too. But I’d add any suspensory injuries. And one to the proximal part of that ligament behind? No way.
