Hi all-
I have a 7-8 yo Cavalier KC with immune mediated poly arthritis, who presents with a pretty good carpal hyperextension issue. I have started with some basic ROM and gentle stretching as his extensors are snug and he has weak flexors. Also put him in the UWTM holding him just above the raised water, and he did the most wonderful dog paddle with his fronts! Wondering which splint would be the best in this case, how long he should wear it per day, what may be contraindicated with an immune mediated problem as this (laser. OK? Some edema perhaps capsular), and any other ideas for strengthening and weight bearing that would not keep him in his hyperextended position. He is a very docile and sweet boy! He is on immunosuppressant Thank you!

Oh- bilateral hyperextensions!

Oh the poor thing.

My usual thinking is to start with something soft, the the Therapaw carpoflex. However in a case such as this, I tend to think that going right to some sort of permanent splint might be best.
Where are you located?
North America - look into Hero (discount for FourLeg Members), Animal Orthocare, Orthopets, K9 Orthotics, (and there are others coming about now too).

My concern for a wrap / soft brace would be that there would be more skin breakdown due to the reduced 'breathability' and the fact that the dog would need to wear them frequently.

Which gets to the 'how often' question. I'd say, if attended and walking is possible / likely (i.e. even in the house) then have something on. The unsupervised times, the dog should be confined to a small room or a pen to avoid over stressing the ligamentous support even further. I'd not let a dog wear a brace if unsupervised... and I'd have it off at night as well.

Strengthening is tricky - because you can't strengthen ligaments (which are the structures letting the dog down!) So, walking with a brace is good for the whole body, and your swimming trick is perfect to try to get flexion from those carpal joints and to strengthen the flexors. To be honest, anything else is futile.

I'd use laser as well - for pain & for inflammation. There's no contraindication there.

Best of luck!

Great thoughts L- thank you!

I will look at the bracing options you mention. I agree that splinted walking will help the whole body, get the forces to line up a little better, and offer some proprioception input.

I will let you all know!
