Hip dysplasia is a common, inherited malformation of the coxofemoral joint that eventually leads to Osteoarthrosis. Several breeds of dogs are affected and the prevalence varies between different breeds. As part of the effort to reduce the prevalence of hip dysplasia and select dogs suitable for breeding, radiological screening is performed by at least 12 months of age. Before the radiological examination the dog has to be chemically restrained, sedated or anesthetized. The sedation protocol used differs between veterinary clinics. The impact of sedation method of the screening result for hip dysplasia has been studied.

The aim of this study was to examine which research had been done on dietary supplements for dogs suffering from Osteoarthrosis. The main questions the author wanted answers to were ?Is there evidence in the research that dietary supplements for dogs with osteoarthritis have effect in such a way that quality of life is increased in these animals??, ?are there any contraindications regarding dietary supplements?, ?who is responsible for the control of safety on dietary supplements for dogs in Sweden? and ?what kind of advice would I give to dogowners about dietary supplements?. To be able to answer these questions the author conducted a literature study of the recent research on dietary supplements for OA in dogs. The results showed that despite the lack of research in this field, some promising research has been done on multiple different supplements.

Joint injury (inflammation) or osteoarthritis is the most common cause of poor performance in the athletic horse. Osteoarthritis is the ensuing degeneration of joint cartilage due to inflammation/injury. The single most important factor in the inflammation cascade of joint injuries is interleukin-1 (IL-1). Until recently, these injuries have been treated with products like hyaluronic acid, cortisone and polysulphated glycosaminoglycans (PSGAG). Several studies have not been able to demonstrate a significant difference in the clinical improvement of joint injuries treated with hyaluronic acid or PSGAG and saline.

Sammanfattning Syfte och frågeställningarSyftet med denna studie var att sammanställa kvalitet på och resultat av studier som undersökt om långdistanslöpning ger artros i höft-, knä- eller fotleder. Finns det vetenskaplig evidens för att långdistanslöpning ger artros i höft-, knä- eller fotleder? Vilka styrkor och svagheter har de studier som försökt utröna om samband finns mellan långdistanslöpning och artros i höft-, knä- eller fotleder? MetodSökning av litteratur utfördes i PubMed, CINAHL, Cochrane Library och PEDro. Detta resulterade i att tio artiklar inkluderades för närmare granskning och sammanställning. Utifrån artiklarnas sammantagna bevisvärde poängsattes och graderades artiklarna efter evidensnivå enligt Statens Beredning för medicinsk Utvärderings (SBU) granskningsmallar för kohortstudier med kontrollgrupper. ResultatEndast en av tio studier visar ett positivt samband mellan långdistanslöpning och artros i höft-, knä- eller fotleder, i detta fall höftledsartros.

Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of Osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.
