Tell me about desmitis of the medial oblique sesamoidean ligament.

It was rather unexpected, but my 4-year-old gelding (Shotgun) was diagnosed with desmitis of the medial oblique sesamoidean ligament on Tuesday in his right front foot.

I have started loping the barrel pattern with him this year, as well as have been introducing him to small jumps for hunter classes. I had the vet appointment scheduled to check my other horse (who notariously starts having problems in June) and to make sure Shotgun was still good to go for his young age. I was fully expecting a clean bill of health for him as he has been performing fine without any problems.

He was 2+ lame on his right front foot during the lameness exam and flexion testing. There is no heat or swelling externally on the leg/foot. We nerve blocked to isloate the area, did x-rays (which were clean) and then did ultrasound to find the small area of fluid.

I am thankful we caught it very early and that the area affected is small. My vet recommended 45 to 60 days off, and keeping him in a small area so that he cannot run around. She said after 3 weeks, I can start hand walking him short distances in straight lines. She instructed me to use DMSO/nitrofurazone for 3 days and wrap it. After that, do cold hosing. I have him set up for an appointment in early August (about 60 days) so that we can recheck him.

I am sad that this is going to put a stop to our progress for the year, but he is young and I’ve had him since he was 6 months old and I want him to last his entire life. So time off it is!

I’ve never had a horse have this type of injury before so I really know very little about it. Was curious for people to share their experiences and outcomes.
