my mare has been short on one leg for a little while and then afew months ago almost started limping but worse on soft ground than anything, went to vets had 2 sets of nerve blocks (was bilateralon front) and xrays not a lot showed up, had wedges put on, went back, had mri but the lameness is now only really on the front left, shes better to "ride" (now on soft round 15mins max of walk with a little bit of trot thrown in and doesn't seem to "limp" as much), this is what they found -
have reviewed the radiographs and the MR study, as well as Rogers Vet Report regarding Venus. Imaging has revealed several findings:
(1) bilateral mild navicular bone pathology (LF worse)
(2) bilateral entheseopathy of the impar ligament (ligament that attaches the navicular bone to the pedal bone)
(3) bilateral lateral chondrocoronal ligament desmopathy (small ligament between the hoof cartilage and the hoof capsule)
(4) bilateral STIR signal in the dorsal distal aspect of P3 (fluid or oedema in the pedal bone)
(5) small dorsal irregularities of the lateral lobe of the DDFT in the presesamoidean area on the LF (irregular surface of the tendon in the foot)
(6) bilateral increased the signal in the middle phalanx, likely within the medulla. (fluid or oedema in the short pastern bone).
In summary, Venus has changes in her navicular bones and in some of the surrounding soft tissues in the foot. None of the lesions appears very extensive in the MRI. However, it is possible to underestimate pathology with a standing low-field MR system. I fully agree with Roger that, if she should be consistently lame, further work-up including a navicular bursa block would be required to weigh the significance (e.g. contribution) of some of these changes to the lameness. This will then allow for Roger and yourself to plan further management of your mare, which could (depending on the response to the navicular bursa bock) consist of surgical or medical treatment.
What is the prognosis for this? rideable? serious? thanks
