Possible fracture?

[Huckleberry]

Took Flint in this morning despite my husband and I being pretty sick and didn't get very good news. The said he has angular limb deformity. When we got to the vet we noticed he was already starting to bend his other leg out as well, although nothing like the right leg. Carpal valgus bilateral with fetlock tendon laxity is what he said. He has 35% deviation on the right leg and 20% on the left. They said we can splint him for several weeks and hope to solve the tendon laxity, but he most likely will not have a future as a packer. I'm incredibly bummed about this and don't understand how it happened so quickly. The vet said he wasn't sure as to the cause either, they are usually born this way, but Flint has never appeared to have had an issue before. We did hoof trims on New Years and he appeared normal. I asked if it could be a mineral or diet issue and they said possibly. We purchased him from Carolyn Eddy so I don't think it would be a hereditary deformity. He was raised on his mom and then switched over to orchard grass hay with free choice minerals. The plan for now it to take him in weekly to re splint and go from there. Any insight or thoughts would be much appreciated.

Here's a pic of the poor fellow, just glad to be back home.
