I was just called up by the owner of the stallion I was planning to breed to. He is 13 years old and had previously been radiographed for stallion approvals and evaluated free of OCD. He has been actively competing in eventing.
He recently was slightly off in one hind leg and a radiograph today revealed a cyst in the stifle.
It is as yet unclear if his stifles were radiographed for the stallion approvals. Of course if his stifles weren't radiographed before then it I would have to assume the cyst has been there all along. However, if they were radiographed four years ago and were clean at that point, would this bone cyst be of a concern for his use as a breeding stallion? Could it then be a result of an injury?

A little more info: Diagnosis subchondral cyst medial condyle.
Previous radiograph clear: lateral-medio projection of stifle.
Would that projection have exposed a bone cyst in the medial condyle?

FWIW. they xrayed my filly with stifle ocd~ lat/med and also front to back or whatever its called ~ they took 2 views.
she had the exact same diagnosis. And then ended up with wobblers and had to be euth. i think i read that wobblers and ocd are somehow strangely related. bone problem
just my story...i have no idea if it correlates to yours.

Lisa, if the horse has a OC lesion that is causing lameness, I would not breed to the stallion. We are increasingly sure disease from OC lesions has an important genetic component.

Thanks Dr. O. Can a subchondral cyst not also be due to an "innocent" injury? He radiographed clean four years ago, also in the stifle, and he has had an active eventing career. 13 years old and never had a problem with lameness before...and this time just slightly off.

When you ask can it be...there is nothing in this world that is 100%. Defects of endochondral ossification are pretty characteristic so you should discuss this possibility with the person that has reviewed the original radiographs.
