CONTRIBUTIONS TO THE BIOMECHANICS OF THE HIP-JOINT WITH NEW ASPECTS CONCERNING THE DIAGNOSIS OF HIP-DYSPLASIA - CONSTRUCTIVE CRITICISM OF HD DIAGNOSIS AND CURRENT PRACTICES WITH RESPECT TO THE FUTURE

In absence of basic canine hip biomechanics, an own consequent three d imensional concept to evaluate the coxofemoral joint was developed for the dog. With the help of a new method to radiologically demonstrated the hip in a physiological standing position several new clinically r elevant aspects could be further investigated. For example the breed s pecific anatomical differences in the hip, and dynamics and the backgr ound on <<iatrogenic luxations>> in HD diagnostics could be shown. The caudal luxation and the growth abnormalities of the hip and their con sequences on the whole leg (antertorsion syndrome) as a consequence of inadequate breeding could be demonstrated.
