[Purpose] To study preoperative and postoperative hip circumference data of various types of congenital dysplasia of the hip treated with total hip replacement, including the femoral offset, femoral neck length, height, and hip abductor arm parameters. [Subjects and Methods] This study included seventy-eight cases of congenital dysplasia of the hip (I-III type). Furthermore, four parameters wer...

OBJECTIVE The objective of this study was to investigate a possible relation between congenital hip dysplasia and acetabular retroversion and to explore the eventual influence of the latter in the surgical decision for periacetabular osteotomy. MATERIALS AND METHODS We assessed the classical morphological characteristics of both hips, with an additional newly described retroversion index. The...

I write in response to the letter written by Drs. George Hartofilakidis and George Babis commenting on the use of the term ‘‘developmental dysplasia of the hip’’ rather than ‘‘congenital hip dislocation.’’ There is currently no classification system or terminology that sufficiently captures the spectrum of pathology that can be seen in the newborn hip. Currently the term ‘‘developmental dysplas...

Il est incontestable que les troubles du développement de la hanche sont un sujet d’une importance capitale en pédiatrie. Le terme dysplasie comprend large spectre malformations sévérité très variable qui, non décelées ou traitées, peuvent avoir des conséquences graves à court long pour personne concernée. «luxation congénitale hanche» (congenital dyslocation of the hip, CDH) utilisé auparavant...

In this case report we present a patient with bifocal pubic rami stress fractures after contralateral total hip arthroplasty for congenital hip dysplasia and longstanding ipsilateral hip fusion. Treatment protocol for patients with various degrees of hip arthritis on one side and contralateral longstanding hip fusion are proposed based on the literature and our and previously published cases.

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 dys...

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...

The term "developmental dysplasia or dislocation of the hip" (DDH) refers to the complete spectrum of abnormalities involving the growing hip, with varied expression from dysplasia to subluxation to dislocation of the hip joint. Unlike the term "congenital dysplasia or dislocation of the hip," DDH is not restricted to congenital problems but also includes developmental problems of the hip. It i...
