title: Evolution of the term and definition of dysplasia of the hip - a review of the literature.
abstract: There is no consensus on the definition of dysplasia of the hip (DH). Past and present concepts used to describe DH do not form a complete view of the pathology. Moreover, some authors still present the disease as congenital, not developmental. This prompted authors to analyze the evolution of the definition of DH. Based on the biomedical databases 500 articles and books in the field of hip dysplasia were found and analyzed. Fifteen definitions of hip dysplasia met inclusion criteria, subsequently were analyzed and presented in chronological order. The analysis revealed that currently there is no single, universal definition of hip dysplasia in the aspect of morphological, clinical, and radiological studies. Despite the widely-used term of DH, it is described imprecisely and in different ways. Therefore, it is necessary to develop a multidisciplinary definition of this pathology covering all aspects of hip disorders considered valid in modern orthopaedics.
