Summary

In order to look for phenotypic correlation between hip (HD) and elbow (ED) dysplasia, we used radiographic scoring obtained from 1,411 dogs of different breeds, which were evaluated for authoritative grading of both conditions. In this population, we found that the risk ratio for an animal to be simultaneously affected by HD and ED is 1.67. For a dog with ED, the risk ratio to be affected by HD increases as the ED grade increases. Similarly, for a dog affected by HD, the risk ratio to be affected by ED increases as the HD grade increases. In a dog affected by HD or ED, the clinician should look for the second condition in the same animal. Due to the low, yet positive correlation, selection against one trait will not affect the other trait sufficiently. Therefore selection has to be conducted at reduction of HD as well as reduction of ED.

Within this Öffnet externen Link in neuem Fenstercurrent issue of VCOT, Nicolas Jardel et al discuss an anatomical study which they conducted in which 20 canine cadaveric elbows were used. The aim of this study was to describe the relationship of the major muscular, ligamentous and neurovascular structures in relation to standard medial elbow arthroscopic portals used in dogs.

WVOC 2010

From the 15th to the 18th of September, 2010, the next World Veterinary Orthopaedic Congress will be taking place in Bologna, Italy. ESVOT, in collaboration with VOS and the University of Bologna, will be organising this event, which only takes place in Europe once every 8 years. There will be an excellent programme for both large and small animals, pre-congress courses and seminars, in-depth seminars, as well as extra-curricular activities.
