Hock pathology

Bone loss appears to affect both sides of the joint making osteosarc less likely and an inflammatory or immune mediated condition more possible. Joint taps may yield some information, or biopsy if you're happy to take a chunk out of such a narrow, moth eaten bone without causing fracture! Symptomatic treatment and prepare owner for amputation?

It's not so much the instability I'm worried about but what's going on inside that moth eaten bone.

I'd say do stressed views to be sure of the direction and level of instabilty.

The crepitus might be from the djd or i suppose there could be a fracture in there somewhere.

When it's held in place and flexed is there crepitus?

Sorry contralateral normal.

It's unstable mediolaterally with a bit of force. Worse medially. Craniocaudally stable. Crepitus pronounced. Swollen and sore.

Are the chronic changes in this hock also seen on the contralateral joint. If not they may be related to the previous trauma.

On the cc view it look like the fibular malleolus is fractured but the hock looks like it luxates laterally which wouldn't fit. There is a big effusion of the tibio-tarsal joint.

In which/how many directions is it unstable?
