Are they the same thing? Mare has been diagnosed with the latter following nerve blocks/scans in her off fore. Low grade damage but can't tell if aggravated old injury or fresh damage. Have been instructed to bute/field rest for 4 days then see how she is.

Amy experiences? Good or bad. Also does Proximal Seasmoid Desmitis differ from full blown Proximal Suspensory Desmitis?

Thanks
 
Have no experience with this condition but it is totally different to proximal suspensory desmitis (PSD); the proximal sesamoids are 2 small bones at the bottom of the cannon bone at the back of the fetlock. The sesamoidean ligaments, which i assume are the ones showing changes in this case, run from the sesamoid bones down the back of the pastern to which they then attatch. I would imagine that the prognosis for this condition would be better than for PSD and recovery time would be shorter but as i said have never seen it so could be wrong. Hope this helps!!
 
Thanks, am totally confused as damage is behind the knee where the suspensory ligament attaches to the bone, but I thought the vet mentioned sesamoids.
 
Not necessarily it could well be desmitis of one of the sesamoidean ligaments. My mare is retired following a tear of the proximal end of the straight sesamoidean ligament.
 
there's no such thing as proximal sesamoid desmitis. i think you're getting confused.

PSD is proximal suspensory desmitis - inflammation of the suspensory ligament at its attachment just below the knee.
 
I swear the vet did mention sesamoids at time (my Mum thought so too) and googling it confirms that there is such a thing but it occurs at the fetlock, which is why I was totally confused as I knew the damage was at the back of the knee!

Anyway, checked with vet yesterday and it is proximal suspensory desmitis. Scan showed the damage to be a fuzzy boundary where the ligament attaches to the bone, no holes/tears and she was 2/10 lame. Took him a while to find the damage as it's not immediately apparent

Star - what sort of prognosis have you seen with PSD in the foreleg? Vet has told me bad short term but good long term but this contradicts everything I've ever heard about PSD!
 
better in frontlegs than hindlegs. both benefit hugely from shockwave. preferred treatment regime is 6wks box rest with 3 lots of shockwave 2wks apart, then ridden walking for 2mths, trotting for 2mths then canter work - all in straight lines before starting schooling again.
