Re: Performance dog pups, PennHip and JPS

[Guest guest]

Hi CarolI think evaluation the hips of prospecitve performance pups around 16 weeks of age would be great, especially as JPS seems to have promising outcomes. I am working with a few adult performance dogs right now who were diagnosed with hip dysplasia but are doing well (so far). And I wish I would have known about JPS 3 years ago.Unfortunately, with this procedure we have to rely on the owners not to submit X-rays later on or to breed those dogs.The only long-term study I am aware of isLong-term outcome of juvenile pubic symphysiodesis and triple pelvic osteotomy in dogs with hip dysplasia.Manley PA, WM, son KC, Dueland RT, Linn KA.J Am Vet Med Assoc. 2007 Jan 15;230(2):206-10.Antke--- Dr. Antke C.

The science is not that great … but the last paper from the Wisconsin group showed (I think) that hips that are too loose could not be helped using JPS but there might be some benefit for dogs having DI’s between 0.5 and 0.7. These are not cut in granite and I think this would be a good opportunity for a group like ours to conduct a randomized, controlled, and if possible, blinded clinical trial on the efficacy of JPS. Aldo Vezzoni is selling it as a done deal in Italy and throughout Europe and because it can be a source of new revenue in the depressed veterinary market it resonates with practitioners. The science needs to come first: ready, aim, fire, NOT ready, fire, aim!Best,Jan

Interesting question about doing "prophylactic" JPS, but it seems that DVMs who care for performance dogs aren't ready to start advising JPS based on results of joint laxity at an early age. Their opinion might be summarized as "Penn Hip is based on the theory that prepuberal joint laxity is an accurate predictor of phenotype, which remains to be shown." Articles like the one below from 2009 show either no correlation or only moderate correlation. Maybe someone else has some relevant study findings.

Comparison of clinical, radiographic, computed tomographic, and magnetic resonance imaging methods for early prediction of canine hip laxity and dysplasia.

Abstract

The purpose of the study was to use two palpation methods (Bardens and Ortolani), a radiographic distraction view, three computed tomography (CT) measurements (dorsolateral subluxation score, the lateral center-edge angle, and acetabular ventroversion angle) and two magnetic resonance (MR) imaging hip studies (synovial fluid and acetabular depth indices) in the early monitoring of hip morphology and laxity in 7-9 week old puppies; and in a follow-up study to compare their accuracy in predicting later hip laxity and dysplasia. The MR imaging study was performed with the dog in dorsal recumbency and the CT study with the animal in a weight-bearing position. There was no association between clinical laxity with later hip laxity or dysplasia. The dorsolateral subluxation score and the lateral center-edge angle were characterized by a weak negative correlation with later radiographic passive hip laxity (-0.26 < r < -0.38, P < 0.05) but its association with hip dysplasia was not significant. There was an association between early radiographic passive hip laxity and synovial fluid index with later passive hip laxity (0.41 < r < 0.55, P < 0.05) and this was significantly different in dysplastic vs. nondysplastic hips (P < 0.05). There was no association between the remaining variables and later hip laxity or dysplasia. The overlapping ranges of early passive hip laxity and synovial fluid index for hip dysplasia grades and the moderate correlations with the later passive hip laxity make the results of these variables unreliable for use in predicting hip laxity and dysplasia susceptibility.

First of a huge thanks to TheraPaw for the recent conference. It was a long way to travel, but well worth it.

I'm looking for information and opinions about the idea of evaluating hips on prospective performance dog pups at/about 16 weeks of age and following up with JPS (juvenile pubic symphysiodesis) if the score and physical exam warrant the procedure.

To my knowledge, there is no published data looking at this but I'd love to get my hands on it if it's out there.
