Enostosis; fibrous osteodystrophy; juvenile osteomyelitis; eosinophilic panosteitis. Panosteitis is said cabine be a common disease of German shepherd dogs.

It is characterized by inflammation of the bone marrow, especially that of the limb bones, with episodes of bone pain, which can be severe, and lameness in young German shepherd dogs.

It is thought to have a genetic basis but the genes involved have not been determined. Panosteitis is an inflammatory disease primarily of the fatty bone marrow with subsequent effects on the surrounding panosheitis Shell It can occur in any bone which contains significant volumes of pxnosteitis marrow, long bone shafts being the most common sites. Generally affecting juvenile male German shepherd dogs GSDsthe disease is usually self-limiting and spontaneously regresses once sexual maturity is reached, although some individuals may be affected up to middle-age Bohning et alBerry Affected dogs may be lethargic, show a loss of appetite and have a raised temperature.

The dog may show a pain response on panosreitis handling. Reoccurrences may coincide with panotseitis of stress Shell During active bouts of panosteitis, affected GSDs exhibit signs of significant limb pain. Affected dogs also often feel ill due to fever. Affected GSDs may suffer recurrent bouts from five months of age, lasting from a few days to weeks, although they may last longer.

The disease usually resolves when the dog reaches sexual maturity, at between months, but some dogs are affected until middle-age. The GSD is the breed most commonly affected with panosteitis. The genetics of panosteitis have not been studied and the genes responsible for the condition have not been determined. There is no genetic test for the disease. It is not known if unaffected carriers of the gene s exist – animals that do not have the disease themselves but are able to pass on the gene s that cause the disease to their offspring – and, as far as we know, there is no information about the heritability of panosteitis in GSDs.

As far as we are aware, there are no breeding schemes aimed at reducing the incidence of panosteitis. Generally it seems sensible not to breed from individuals that have been affected by the disease or from their relatives. For further details about this condition, please click on the following: Panosteitis is an inflammatory disease that generally affects the long bones of young, large breed dogs, especially GSDs.

Primarily it affects fatty bone marrow and has subsequent effects on the surrounding bone Shell It can occur in any bone that contains a significant volume of marrow but, as marrow is largely found in the diaphysis shafts of the long bones, these are the most commonly affected sites.

Long bones are the bones of the limbs. They are essentially supporting columns that have to carry the weight of the animal.

These epiphyses have an outer layer of compact bone and spongy bone in their centre. Between the epiphyses and the diaphysis in young animals are the growth, or epiphyseal, plates which are the zones in which bone lengthening occurs. The diaphysis the shaft of the bone has, in cross section, an outer thin fibrous layer of tissue called the periosteum and, inside this, a wide layer of compact bone which provides the strength.

In the centre of the shaft is the bone marrow cavity that contains the soft, blood cell producing, haemopoietic bone marrow and yellow fatty bone marrow. Bone is a dynamic, living tissue that can slowly respond to the forces exerted on it by remodelling, strengthening and repairing itself. To do this it has cells called osteoblasts which produce bone and osteoclasts which dissolve it.

In animals affected with panosteitis, the fat cells of the yellow marrow degenerate, inflammation occurs and this tissue is replaced with fibrous tissue, which in turn is calcified and turned into spongy bone tissue, as osteoblasts, osteoclasts and fibroblasts fibrous tissue-producing cells are activated ShellBrooks Ultimately, as the disease process subsides, this new bone is removed as part of the normal bone remodelling processes and the fatty marrow regenerates.

The causes of panosteitis are unknown ShellBrooks Various possible causes have been proposed as listed below. Generally affecting juvenile dogs, the disease is usually self-limiting and spontaneously regresses once sexual maturity is reached between months of age, but some individuals may be still affected in middle-age Bohning et alBerry Males are affected more frequently than females Trostel et alShell These signs often last from a few days to a few weeks, disappear and then reoccur i.

Handling the limb may elicit a pain response. Reoccurrences of the signs may coincide with periods of stress Shell Until spontaneous regression of the condition occurs, pain-relieving medicating is often needed and reduction of stress and activity levels are also recommended Shell During bouts of panosteitis, affected GSDs exhibit signs of significant limb pain. They react to having the affected bones touched.

Shell stated that: The disease usually starts at between five and 18 months of age and is often recurrent.

It regresses in most individuals once they reach sexual maturity at between months, but some Canien are affected until they are seven years of age Bohning et alBerry Individual bouts may last panosteeitis weeks to months at a time Shell Panosteitis may be suspected panosteiitis a juvenile GSD showing lameness.

However other orthopaedic conditions also commonly occur in young GSDs so confirmation of the diagnosis needs to be made using radiography x-rays ShellBerry The radiographic appearance of the tissues of the bone changes during the course of the condition and such radiographic changes lag behind the clinical signs by about days so it is possible for an affected dog to have initial lameness without being able to detect corresponding radiographic changes Shell This can make diagnosis difficult.

Blood tests may show an eosinophilia higher than normal concentrations of a particular white blood cell panosreitis Shell With the current state of knowledge it is difficult to give good advice. Generally it seems sensible not to breed from individuals that have been affected by the disease or which have more than a very few affected relatives including siblings and siblings of parents Bell Prospective dog owners may wish to avoid acquiring dogs of breeds in which there is a high prevalence of the pwnosteitis in order to help avoid perpetuating the problem unless they are able to ascertain that the disease does not occur or is very rare in the particular lineage of the dog they are interested in acquiring.

Clinical and pathological effects Panosteitis is an inflammatory disease that generally affects the long bones of panostitis, large breed dogs, especially GSDs. The theory is that high protein levels lead to oedema fluid collection and retention within the tissues of the medullary cavity. As the bone is rigid this extra volume of fluid causes compression of blood vessels and to inadequate blood supply to the tissues of the bone, leading to panostsitis ischaemia Schawalder et al a, b, Shell Because some breeds of dogs including GSDs and Bassett hounds are predisposed to the disease, the implication is that there may be a genetic cause to the condition Brooks Stress is often thought to play a role Shell Return to top 2.
