    PROCEEDINGS 27th annual meeting of the INTERNATIONAL ELBOW WORKING GROUP April 11th 2012 ICC, hall 7b Birmingham, UK The International Elbow Working Group acknowledges the financial support by HILL’S PET NUTRITION 27th annual meeting IEWG, Birmingham UK, April 11th 2012, p 2 WELCOME ADDRESS Birmingham, April 2012 Dear IEWG-congress participant, The International Elbow Working Group (IEWG) has been founded by a group of veterinarians and dog breeders in Davis, CA, U.S.A. in 1989 with the aim to increase the knowledge on and awareness of elbow disease in dogs, and to support all stakeholders in disseminating new knowledge in this field. The interest in hereditary aspects of elbow dysplasia (ED) has been increasing ever since both among breeders and veterinary surgeons and radiologists alike. ED has been recognized as a cause of lameness in a large variety of dog breeds with an incidence as high as 50% of the screened dogs. Published data on prevalence vary depending on breed and country. These discrepancies can be a matter of screening bias (e.g. not including dogs suffering from the disease and treated at a young age, or not submitting films of affected dogs for official screening), of improvement gained by the implementation of breeding restrictions for affected dogs, or may be caused by different screening or grading modes. The latter emphasizes the necessity of uniform grading, preferably by the protocol introduced and refined by IEWG and in use in many countries for many years. Some research groups are in a process of performing molecular genetic research in the field of canine elbow dysplasia, to use the results in the future for screening of potential breeding stock.

  • Australian Cattle Dog Health Testing
    AUSTRALIAN CATTLE DOG HEALTH TESTING “BREEDER OF HEART” REQUIREMENTS All purebred or mixed breed dogs can have genetic and other health issues. Testing the sire and dam before breeding is a way to decrease the frequency of or prevent disorders. Your breeder should be willing and able to discuss health and genetic issues found in your chosen breed. Your breeder should also be willing to show you the proof of testing. They should be able to verify which dogs the tests relate to through means such as microchips or tattoos that correspond to the test results. They should be willing to give you copies of tests related to your new dog. Look at what the actual test results say and do your research at sites like http://www.offa.org (Orthopedic Foundation for Animals) and http://www.acdhew.org (Australian Cattle Dog Health, Education and Welfare) to understand what they mean. Even if your breeder does all suggested testing, health challenges may still arise as these are living creatures, not machines. However, as a result of testing the parents and careful breeding based on testing, the likelihood of getting a healthy puppy is higher. Testing should be done on the sire and dam before breeding as described below. Some tests can also be performed on puppies, as noted. On DNA tests, the point is to avoid producing “affected” dogs. “Carriers” of disorders can make perfectly fine pets but should only be bred to “clear” dogs to avoid producing more “affected” dogs. Sometimes the breeder has done generations of tests to produce “obligate” clear dogs so the puppies themselves are no longer tested for certain disorders.

  • Assessment of Canine Elbow Joint for Osteoarthritis and Treatment with Synovetin OA®
    Assessment of Canine Elbow joint for osteoarthritis and treatment with Synovetin OA® Steven M. Fox, MS, DVM, MBA, PhD PAIN Pain is the clinical sign most frequently associated with osteoarthritis (OA).1 The clinical manifestation of this pain is lameness. When an animal presents with clinical lameness, a determination must be made whether the animal is unable to use the limb or is unwilling to use the limb. Inability to use the limb may be attributable to musculoskeletal changes, such as joint contracture or muscle atrophy. These anomalies are best addressed with physical rehabilitation. On the other hand, unwillingness to use a limb is most often attributable to pain. Herein, lameness is an avoidance behavior. Ironically, articular cartilage is frequently the focus of studies regarding OA. However, clinical treatment of the OA patient is most often focused on the alleviation of pain. Appreciating that articular cartilage is aneural, the focus of OA pain management resides in the periarticular structures. No pain is elicited by stimulation of cartilage, and stimulation of normal synovial tissue rarely evokes pain.2 OA pain is the result of a complex interplay between structural change, biochemical alterations, peripheral and central pain-processing mechanisms, and individual cognitive processing of nociception. The source of pain in the joint ‘organ’ is multifocal: direct stimulation of the joint capsule and bone receptors by cytokines/ligands of inflammatory and degradative processes, physical stimulation of the joint capsule from distension (effusion) and stretch (laxity, subluxation, abnormal articulation), physical stimulation of subchondral bone from abnormal loading, and (likely) physical stimulation of muscle, tendon, and ligaments.

The term osteochondrosis refers is an abnormal development of the cartilage on the end of a bone in the joint Osteochondritis dissecans (OCD or OD) is an inflammatory condition that occurs when the diseased cartilage separates from the underlying bone. It most commonly affects the shoulder joint but the elbow, hip, or knee (stifle) may also be involved. Which dogs are likely to be affected by this condition? This is a developmental disease that occurs in rapidly growing medium to large breed dogs typically between 6 and 9 months of age, and may occur more often in male dogs. "...limiting dietary intake of energy and calcium reduces the incidence of this condition..." This disease is more common in dogs receiving too much energy and calcium in the diet. Studies have shown that limiting dietary intake of energy and calcium reduces the incidence of this condition, and of other developmental orthopedic conditions. What are the symptoms of OCD? Dogs that are affected with OCD typically limp or are lame in the affected leg or legs. During an orthopedic examination, when pressure is applied to the affected joint, or when the joint is manipulated, the dog will often cry out in pain. The affected joint may be swollen and warm to the touch. In some cases, the lameness may be mild and intermittent while in other cases, the dog may be in constant pain, and avoids bearing weight on the affected leg.

  • Update on Diagnostic Imaging in Elbow Disease. I
    Update on diagnostic imaging in elbow disease. I. Gielen, B. Van Ryssen, H. van Bree Department of Medical Imaging & Small Animal Orthopaedics. Veterinary Faculty Ugent Elbow dysplasia (ED) is characterized by varying degrees of elbow incongruity, bony fragments (bone chips), and ultimately, severe arthrotic change. The term was introduced to describe generalized osteoarthrosis (arthrosis) of the elbow joint in which the anconeal process may be ununited (UAP), the medial coronoid of the ulna may be fragmented (FCP), and osteochondrosis of the humeral condyle (OCD) may be present. These three aetiologies resulting in ED can be present individually, but it is important to note that there can be considerable overlapping in their presence. In diagnosing ED there a two different issues: there is the need for selecting ED free breeding stock and there is the diagnosis of the condition in the individual patient presented for forelimb lameness. For selection purposes, most of the time the secondary degenerative joint (DJD) changes are scrutinised by means of radiographs and mostly the individuals are not suffering lameness. For the individual patient the early diagnosis of the primary lesion is very important because an early treatment guaranties a better prognosis. The diagnosis of elbow dysplasia in lame dogs is made from a combination of clinical signs, palpation (manipulation) of the joints, and medical imaging. A wide range of imaging options is now available but the “perfect” imaging protocol does not exist because each modality has his strengths and limitations. Economic considerations will also have to be taken into account. In case where the clinical examination is not providing a clear localisation or in case of uncertain radiographic findings, scintigraphy is a useful technique to localise the cause of lameness.
