Thanks, I've looked up a few other papers on pubmed (ie just the abstracts) that reflect similar findings on the subject. Its difficult to tell if they corrected for weight / condition score as neutered dogs tend do be more obese than uneutered, so is the increased incidence due to the neutering or just because, as a population, because they are higher condition score?

Hopefully not a current vet student; you'd think they'd be able to do a literature search. For starters:

About 6 months ago I saw a case of unilateral avascular necrosis of femoral head in a 10 month old British Shorthair cat that had been neutered at 4-5 months of age. I don't know whether it is coincidence or not or whether it is breed related. I have seen the odd case in British Shorthairs before.
