I think it’s impossible to answer that question on a forum tbh. There are no guarantees horses will stay sound with or without the issues shown in the X-rays. The sidebone on the LF is significant so in 6yo it would put me off. Actually that much sidebone in both feet at 6yo would put me off. Sidebone indicates instability in the leg so there may be problems higher up which are causing it. Having said that once it’s formed it doesn’t seem to cause too much of a problem in itself. The foot balance on each foot is not good but that could be improved with good trimming/farriery.
If this is a horse you are looking to buy I would walk away. If you own it already then work it as you aim to and see if it stays sound. If it doesn’t look higher up and see what’s happening there.
Some of them stay sound with X-rays like that. Some of them don’t.
