Five year old greyhound with chronic lameness of uncertain origin in right fore. We&#39;re fairly sure that there is pain on forced extension of right shoulder (vs no reactionw ith same on left), anden-USTelligent Community 10https://www.vetsurgeon.org/thread/35624?ContentTypeID=1Tue, 29 Mar 2011 08:28:04 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:f62c7993-4eb2-427a-91e0-a743cef31ca8Chris Barker<p>Have to agree this is probably an incidental finding&nbsp;&nbsp;&nbsp; Given that this is a &#39;chronic&#39; lameness I&#39;d expect more secondary OA changes&nbsp;&nbsp; Joint space looks even and consistent with others at the same level, there are no periarticular spikes/osteophytes or significant periarticular soft tissue swelling, and the &#39;fracture line&#39; looks very smooth and the distal portion of the sesamoid rounded.&nbsp; Also this is one of the &#39;typical&#39; sites for bipartite sesamoids&nbsp;&nbsp;&nbsp; Suspect the sourse of lameness lies elsewhere</p> <p>Chris B</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/35623?ContentTypeID=1Tue, 29 Mar 2011 08:10:55 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:a12dec3f-66a5-432a-92c0-da89e3c57d7asharon rankin<p>On further thinking, I do recall from college days that traumatic/stress fractures of the sesamoid were common in racing greyhounds-( mainly digit 5/ sesamoid 7) but I thought this would have been more common on the innermost leg which takes most of the stress on racing&nbsp;ie the&nbsp;left. I would have thought if significant however,&nbsp;pain on deep palpation would be evident. Sorry, I&#39;m of little help- I&#39;ll defer now to someone more knowledgeable <img src="https://www.vetsurgeon.org/emoticons/v2/Ashamed_smiley.png" alt="Embarrassed" /></p> <p>Sharon</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/35620?ContentTypeID=1Mon, 28 Mar 2011 22:43:47 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:1fad94ff-0857-474e-958f-b868cc37040fsharon rankin<p>Hi there!</p> <p>Certainly no expert, but looks like a&nbsp;bipartite sesamoid- v common in Rotties but also occur frequently in greyhounds. Would say this is an incidental finding but perhaps the orthopods may say otherwise..?</p> <p>Sharon</p><div style="clear:both;"></div>
