Well, tomorrow is the big day. Tully is booked in for a plantarsal (plantar-tarsal) arthrodesis, which is plates and screws in the hock region. It will keep her hock rigid but allow her to put pressure on that leg. It's all worrying, the complication rate is quite high (33% for a major complication like loss of limb or death and 42% for a minor complication). And because Tully is old, and has an autoimmune disease the odds worsen. Even loss of limb would be bad for Tully because her other hock is on the way out so she would basically lose the use of her back legs altogether (and her shoulders aren't that great after ball chasing and dog sports). Both specialists think she should be PTS if that was to happen. I've had two different opinions from two different ortho vets. One says leave it and just keep her in a splint until she can no longer walk, the other says do the surgery and give her a quality of life. The first option has become less and less viable - she's chewed her leg to bleeding over the top of the splint, her leg keeps twisting underneath her when she falls, she's being knocked over all the time and I have to keep carrying her up stairs with my bad back and of course, she still wants to chase . Leaving it in a splint will mean the other leg will fail at some point and I'll have no other options then. I'm pretty upset. It's dire times. I know I'm always amazed how Tully bounces back but each illness just makes her more fragile and she's had her fair shared of illness over the last year. I have to give her a fighting chance, but this one is going to be tough. Tully is 13 years and 8mths old.
