    Default Navicular

    Hi:

    Does anyone know how long it would take for a horse to show Navicular damage on an X ray?

    We bought our horse sight unseen from a dealer in Europe and were shown a clean set of x rays. Eighteen months later his x rays show acute navicular deterioration. Does anyone know how long it would take for this to show up? We're wondering if they switched original x rays on us.....

    What is the area of specific damage and deterioration diagnosed from the x-rays?

    Default Navicular

    Not really sure where - the vet said he is showing lots of little lesions - maybe the coffin bone? The vet also said that its one of the worst cases he's seen in a younger horse so I wondered how long it takes to get pretty bad like this.....

    What are the clinical external symptoms that prompted the x-rays? 'nuther words, has the horse become lame over time and you got x-rays as part of a lameness diagnostic workup?

    Did the current vet compare the current x-rays to the previous x-rays taken before the horse was purchased?

    You can have navicular changes show up in months on rads, but usually horse has been experiencing progressive low-grade lameness for a while before rad changes are noticeable. Has your guy been lame for a while? You say he has "acute navicular deterioration," which can mean a variety of things - an isolated impar or DDFT injury (unlikely, but possible), an infection, mild laminitis etc.

    You can also have severely lame horses that block to the heels with no evidence of navicular involvement. It totally depends on the individual horse and what exactly is going on.

    Sorry to hear, what a mess! Did you not have pre-purchase radiographs done, or were those the ones done 18 months ago (and you've had him this long?). I had a mare pass a vetting at age 12, and retired at age 14 due to navicular. Nothing significant showed up on radiographs, we had to have a bone scan done to see it.

    I would send BOTH sets of radiographs to a board certified radiologist to compare, they may be able to tell if its the same horse or not, or if there infact WAS development on the first set. General costs for a radiologist to read rads is $50 or so...well worth it.

    Are you sure the original radiographs are actually of the horse you've purchased?

    Drastic changes in 18 months would really have me wondering about a bait and switch.
