THE EPIDEMIOLOGY OF DEVELOPMENTAL DYSPLASIA OF THE HIP IN MALES

Abstract

The most frequent type of DDH was high dislocation (28.7%), and the acetabular index progressively increased with the age. The International Hip Dysplasia Institute classification was found to be more reproducible than Tönnis classification. Delayed diagnosis was associated with the absence of risk factors and with bilaterality. <b><i>Level of Evidence III, Retrospective comparative study.</i></b>
