Dropped fetlocks - experiences?

A close friend of mine has just had her 4yo possibly diagnosed with dropped fetlocks (at the back). The first vet identified one dropped fetlock, and basically said he would need to be put down, then the second vet (an older one) identified that both the hind fetlocks are dropping but said he'd rather refer to a specialist and have MRI done before giving him a death sentence.

It's not a huge surprise as this chap was a rescue case and his conformation is a bit all over the place, he's an odd mix of Cleveland, ISH and warmblood. He's grown very fast recently, I think was mal-nutritioned when she got him at 2 so that won't have helped.

He's not in ridden work, was starting to be backed but started going a bit lame hence the investigation. He's intermittently lame even in the field so it's not looking great, and his owner although devastated is realistic and won't keep him alive for sentimental reasons if he's in pain.

So - just wondering if anyone else has had experiences of dropped fetlocks and whether there's anything that can be done, as I haven't come across it before. The owner has asked me to ask around so I thought HHO would be a good place to start...

Yes, I have had experience of a dropped fetlock, and I'm afraid that it did not have a good outcome.

It was my sec D/TB dressage horse. I bought him as an unbroken 3yo, he went lame with a knackered suspensory and had to be retired age 7, and had to be PTS age 10 as the fetlock joint was collapsing and dropping. His final ultrasound scan showed that there was a significant hole running the length of the ligament.

In hindsight, I think that various training 'niggles' were early signs that he was in discomfort, before he actually showed up lame. He had always had very 'springy' fetlocks.

My vet said that previously he had only seen such damage in elderly brood mares.

Not sure why an MRI is required, unless a suspensory injury has already been ruled out? What a shame, in such a young horse.

I'm not sure why they need an MRI - I guess to rule soft tissue issues out? It is so sad, he was never meant to be competitive, just a hack and she's put so much into him to turn him into a healthy young horse from a horrendous wreck of a 2yo so I feel gutted for her.

Look up Degenerative Suspensory Ligament Desmitis where original collagen material is unfortunately replaced by cartilage regeneration.
