DrO,
I have a 12yo horse I bought after being rehabbed with tendonitis. He had swelling on the inside of his RF during the 6 mo. I owned him.
I had a lameness exam done last week and the vet found the problem to be severe suspensory desmitis of the medial suspensory branch, and a fractured splint bone. This was apparently missed by the original vet so it's been chronic for about one year.
The splint bone is bad enough he's scheduled for surgery on Monday.
The suspensory had no core lesions but showed fiber disruption over 23% of the total cross section at the largest part. The total cross section was 2 cm, the comparison on the other leg was 12cm (large boned horse).
I understand from reading your articles and discussions with my vet what the prognosis and treatment is for severe desmitis.
My question is about the splint fracture, I understand it could have happened before, during or after the suspensory injury.
I also understand that the surgery may or may not improve the suspensory but that it's necessary anyway.
But in your experience is it possible that the sonogram will show improvement simply if the irritation is removed from the suspensory? Have you heard of an injury being downgraded or prognosis improved after this surgery?
Thanks, Janice

Welcome Janice,
If I understand your question right the answer is it will depend. Yes a suspensory injury that is related to a sesamoid fracture is likely to improve after the sesamoid fracture is stabilized. However if the fracture does not involve the attachment of the suspensory, say a small basal fracture, I would think improvement unlikely.

Thanks DrO, I've learned more about lameness and treatment on your site than anywhere else.
The fracture is at the distal end of the splint bone. The radiographs show the fracture right where the splint bone begins to angle away from the cannon bone. The button is displaced about 1 in.
There are no avulsions at the sesamoid bone.
My question is more about can the displacement of the splint bone be causing this large distension of the suspensory?
And could the fiber disruptions shown in the sonogram really be related to swelling and really be artifacts not actual damage?
Thanks, Janice

I am sorry Janice, even though you say "splint" repeatedly everytime I read "sesamoid". Unless in contact with the suspensory, and your description does not support he idea, I don't think this is going to have any relation on the suspensory injury. Thanks for the kudos inspite of my terrible reading!
