Hello DrO - I have recently requested a full pre-purchase exam done on a horse I am considering. The Xrays are showing some "calcium deposits on the sesamoid bones where the ligaments attach". Small "lumps" are visible in both hind fetlock areas. No response shown by horse when lumps are "manipulated" I have requested Xrays to be sent to local diagnostic clinic for their evaluation as well. Horse is travelling very well with no signs of lameness. Also passed 3 individual flexion tests on each of his 4 legs with no issues. Can you explain to me what this could mean and if it could be manageable with maintenance?

Welcome Lorrie,
the term for these lesions is enthesiophytes and they suggest either a past incidence or possibly ongoing sesamoiditis. The problem is:
1) Is this a chronic ongoing problem that is quiet right now
or
2) The left overs of a past injury that have healed up to the point the horse might be used in the manner you intend.
The evaluation of their significance is going to take a combination of exam of the horse, radiographs, and a understanding of what you plan to do with the horse. For more on this see "Diseases of Horses » Lameness » Diseases of the Lower Limb » Diseases of the Sesamoid Bones".
