Yes - would love to see those xrays for people who know xrays (I do not).
Please look into the FHO.
When you google it, you will find articles from vet surgery centers that do the THR who say how it's really not a good procedure, vets who will say it's not used anymore, it's a salvage procedure, that it's only used for tiny dogs and cats, and you will pretty much feel like a bad pet owner for doing it.
I just went to my vet with a dog that our rescue director knew of, and the dog's owner. The dog is a 108# Mastiff/Dane mix who has a broken hip. They were quoted either the $6,000 THR or $3000 (?!?) for an FHO but with an additional thousand in rehab. They did not recommend the FHO on this dog. The family, including three kids, were unable to do this, and were afraid that they would have to put their young, otherwise healthy dog down. She goes Wednesday for her FHO at the vet office I go to. Rehab - none in my vet office ever go to rehab, the owners all do it. To say this family is happy is an understatement - you could see the relief in the woman's face.
My vet did say a bigger dog (this giant girl) may be less agile (she probably is anyway!), that the leg length size might be a bit more noticeable, but that the dog would likely do well (as in all surgeries there are potential complications) with the FHO.
With the FHO there is no crate period, no time where the dog can't move, much less worry about them hurting themselves, and I am going to guess, less concern about infection as there are no foreign bodies implanted. Check that though!
My dog who had one is 50# or so, and she's done amazing with it - there is no difference in muscle tone between legs, she may be able to do more than the typical dog - she can jump, pivot, more - but she's a nutball.
Here is the interesting thing - when we were all at the vet, there was a 4th year student from Purdue University - and when the owner was saying that the FHO is bad, and I said salvage, I saw the student make a face like "huh?" Later she told me that at Purdue, the THR is the rare procedure, the one they consider salvage and that the FHO is preferred. Sooooo....a very interesting regional difference.
