So we spent over an hour with the specialist today. He was so sweet and gentle with Tinsel that our little man was quite comfortable before, during and after the examination.
The verdict on the right carpal joint is that the ligaments have been destroyed, a not uncommon occurrence in this breed due to the size of their leg bones vs the size of their bodies. In other breeds it is usually due to traumatic injury such as the shepherd he is currently treating that jumped through a window of a second storey.
There is surgery available which basically is a fusion of the joint. How much fusion is dependant on how much of the 3 segments are involved. We would have to do a stress xray to find that out. Coupled with doing imaging of his hips, the cost is about $1000. The surgery ranges from $2500 - $3200 with approximately 4 months of being in a cast, rehab afterwards etc. etc. There is a risk of sores developing from the plate and screws, or from irritation by the dog if he is bothered by the hardware. Without something done, it will get worse. Often when one goes, another will as well. Apparently shelties are fortunate in that it is usually the lower extremities that become like this as opposed to other breeds which have more knee and hip issues. At present he doesn't appear to have arthritic changes in either his hips or his wrist.
He doesn't think the dysplasia will be as bad as previously predicted by our regular vet. Tin has decent range of motion with no slipping or popping in the joint by manual manipulation. Of course only imaging will tell us to what extent his hips are involved.
The alternative is to have a custom brace made. Cost of this is between $600 - $800. He recommended a place in Toronto for this. He put us under no pressure to have the surgery and is willing to refer us for the brace. Dr. Bouke said that doing a stress xray if we decide not to do surgery, would be purely academic. Also, hydrotherapy would be advised to muscle up his rear to help stabilize his hips but would do nothing for the carpal joint.
We have decided to have our regular vet do the hip shots and have a custom brace made. Until he is actually wearing the brace we won't know if he has to wear it all the time except for sleep or if only for exercise purposes.
I'm really happy that we decided to go see this specialist. BTW. Tinsel was really well behaved during all this. He even took a treat after all the manipulation and bore no ill will to the vet. He then went over to "Auntie Star's" house were he was given 3 beds to choose from, a chew stick, some yummy treats and then she gave him a big kiss on the top of his head. She has only met him once before but he took it like the trooper he is.
