In a strict sense, however, since there can be racial differences among their anatomical morphologies, it is clinically important to reconsider those parameters for the Japanese. In the present study, in order to investigate correlations among hip and pelvic morphometric parameters, frontal radiographs were taken from 98 Japanese adults (60 males and 38 females) without acetabular dysplasia and arthropathy in the standing position. Their mean age was 62.0 \u00b1 16.7 years. The horizontal position of HRC was significantly correlated with the pelvic width in both genders (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mi>P<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.0026<\/mml:mn><\/mml:math>and 0.0010 for the males and the females, resp.).
