Ernest in on limb three of four of pano.Greetings !
I am looking for some advice on a limping problem. We have a 9 month old Basset called Monty, and we're located in the UK. He has started to limp, and we are strugglinga bit with a diagnosis. Our vet in the UK
thinks he has Dysplasia of the elbow, and the prognosis is not all that brilliant on that. On this web site
and elsewhere, there is the whole "Pano" complex, which has a much more positive outcome. Can anyone help me on how one can realistically distinguish between the two ?? We are currently in the vets about once a week, and it ain't cheap ! Rimadyl has been prescribed and taken. We are inclined to try and keep the medication to a minimum. We are unsure about how much exercise has to do with any of this (probably not a lot). We also think that the genetics side has rather more to do with it. What responsibility does a breeder have in a situation like this ? Any thoughts please ?? Monty has been swallowing lots of dietary supplements, omega tablets etc. He has also been getting shots of cartrophen... which ought to help. Plus occasional injectiosn of more massive pain killers. He is not a very happy dog at the moment, which is very sad, since he is, basically, a very happy dog!
So any thoughts or suggestions very gratefully received.

The more likely cause is pano especially considering the dog is male. Males are much more affected by Pano than females. When Toughy went through his bout pano (for LAla don't be so sure on the three of 4 legs Toughy's effected each limb at least twice.) He was diagnosed with an Elbow Incongruity of 6MM. The Vet did not believe this was the cause of the problem because of the breed and tha fact he had see incongruities of twice that amount not effect the breed. A more conservative approach Until a definitive diagnose can be made would seem to be the prudent course of action.Paneosteitis is an elusive ailment occasionally seen in young Bassets.
It is also known as wandering or transient lameness. Attacks are
usually brought on by stress and aggravated by activity, and up to
now, the cause and the cure are unknown. This mysterious disease
causes sudden lameness, but its greatest potential danger may lie in
false diagnosis, resulting in unnecessary surgery...
In diagnosing the cause of a Basset's lameness, a radiograph of the
forelimbs may indicate a condition called elbow incongruity. (Elbow
incongruity is a poor fit between the 3 bones which comprise the elbow
joint.) Studies to date indicate that elbow incongruity is normal in
the Basset and is not the cause of the lameness. It is also suspected
that many of the previously mentioned unnecessary (panosteitis)
surgeries have been performed on Basset Pups just because radiographs
that were taken showed elbow incongruity. A study on forelimb lameness
in the Basset is currently underway at the School of Veterinary
Medicine, University of Pennsylvania. As previously mentioned they
have determined that elbow incongruity occurs in the Basset but
suspect that incongruity rarely causes the lameness. During the course
of the study, conservative therapy will be recommended for all cases
in which panosteitis appears to be the cause of the lameness. In cases
with severe growth deformities or elbow pain associated with elbow
incongruity, surgery may be recommended.[/b]

Of course it does but statisic shows it overwelmingly effect more males than females at about a 4-1 ratio.Pano can, and does occur in female basset hounds.[/b]
There is a nearly 4:1 ratio of males to females affected by panosteitis; the clinical signs are more severe and the disease more nearly chronic in males.[/b]
FWIW Toughy's bouts of pano lasted approx 1 month or a bit more on each leg. It seemed he went from limping on one leg to the next. It effected every limb twice with the left front 3 times. From the time he was 5 month to 18 months he was limping on on leg or another. Pano effects the idividual dog differently so you don't want to put to much stock in what is "typical" because "a typical" is very common in this diseases progression.If your dog does have pano my experience is that it will subside in about three weeks. That's the experience that we have had over the years as well as many other breeders and ownere here in Southern California[/b]
Whether it is very common for the same bone to be the site of recurrence is not a matter of total agreement, although too many owners report it to be so, to ignore that strong anecdotal evidence. One study of 100 consecutive cases at New York’s Animal Medical Center concluded that “after a bone has passed through all phases of the disease, it is unlikely that it will be affected again”, and reported only one incidence of return to a previously ffected bone. Another study released 5 years later held that “recurrence in the same bone was most frequently found in the radius, followed by the ulna...”, but mentioned a 6-month or more interval between episodes in individual long bones.

Canine panosteitis: an idiopathic bone disease investigated in the light of a new hypothesis concerning pathogenesis. Part 1: Clinical and diagnostic aspectsAccording to the research my vet has shared with me over the years, pano is caused by bones growing too quickly. His first question when we have a case, "Is the puppy still on puppy food?" [/b]
Panosteitis, an idiopathic bone disease of young dogs, was investigated in the light of a new, empirically based hypothesis governing its pathogenesis. Extensive clinical observations suggest a close relationship between the incidence of this disease and the commercialization of various protein-rich, high-calorie dog foods. The theory of an "osseous compartment syndrome" provides a hypothetical pathogenesis, which corroborates this findings. An excessive accumulation of protein causes intraosseous edema due to its osmotic effects. Because bone is a rigid compartment, this leads to an increase in intramedullary pressure and compression of blood vessels. Subsequent osseous ischemia leads to a deficient metabolic state (decreased oxygenation, inadequate influx of nutritive substances, local acidosis, decreased removal of metabolites, disruption of local biochemical processes, etc.), and a vicious circle is created due to the resulting local inflammation. The disease is aggravated by increased metabolism due to excessive physical activity. Within the context of a pilot study, clinical, radiographic, scintigraphic and thermographic examinations and a therapeutic trial with benzopyron were carried out. In addition, more modern investigative tools, including osteomyelography, magnetic resonance tomography and intraosseous pressure measurements were used to provide objective data concerning the pathogenesis of panosteitis. In most cases, clinical remission was seen within days of monotherapy with the proteolytic substance, benzopyron (Cumartrin). This finding appears to corroborate our hypothesis.[/b]
So, as I said, female bassets can get panosteitis. Personally I haven't seen a 4:1 ratio and neither have some of my friends who have been breeding for many years. I trust their experience over some limited study. It may be true that more males get it, but not at that ratio. This may be partly due to the fact that most basset hound males seem to be larger and heavier than the females. BTW - My ratio to date has been almost 1:1, but that's an a very limited number of bassets.Of course it does but statisic shows it overwelmingly effect more males than females at about a 4-1 ratio.
