OBJECTIVES To determine the agreement between observers and to investigate the effect of observer experience in diagnosing canine hip dysplasia and providing final scoring of hips using the standard ventrodorsal hip-extended radiographic method. The agreement of the final scoring, with a presumed correct assessment based on the Norberg angle, is also investigated. METHODS Thirty observers wer...

BACKGROUND The prevalence of hip dysplasia is 1 in 1000. Several pelvic osteotomy methods have been developed to prevent early osteoarthritis, such as triple osteotomy. In this study we are going to introduce our new technique that was done on 4 patients with favorable short-term results. METHODS Four patients underwent triple osteotomy and fixation using a reconstruction plate and early weig...

There has been an increasing demand for hip resurfacing as an alternative to total hip arthroplasty. A number of reports have been published recently detailing the technique and role of resurfacing in a variety of extra-articular deformities, dysplastic conditions, and settings of retained intramedullary hardware and other impediments. The following report proposes a classification system that ...

The mathematical models and the corresponding computer program for determination of the hip joint contact force, the contact stress distribution, and the size of the weight bearing area from a standard anteroposterior radiograph are described. The described method can be applied in clinical practice to predict an optimal stress distribution after different operative interventions in the hip joi...

Decades of selective breeding to reduce the prevalence of hip and elbow dysplasia (HD and ED) in Swedish dogs, based on phenotypic assessment of radiographic hip status, has had limited success. The prevalence of dysplastic dogs is still high in many large-sized and giant breeds and among the most common causes for euthanasia and costly veterinary care in numerous breeds are joint-related probl...

Developmental dysplasia of the hip (DDH) or congenital hip dysplasia (CDH) is the most prevalent developmental childhood hip disorder. It includes a wide spectrum of hip abnormalities ranging from dysplasia to subluxation and complete dislocation of the hip joint. The natural history of neglected DDH in adults is highly variable. The mean age of onset of symptoms is 34.5 years for dysplastic DD...

Total hip replacement for developmental hip dysplasia is challenging. The anatomical deformities on the acetabular and femoral sides are difficult to predict. The Crowe classification is usually used to describe these cases - however, it is not a very helpful tool for pre-operative planning. Small acetabular components, acetabular augments, and modular femoral components should be available for...
