Summary
Acetabular and centre edge angles were measured on normal radiographs of 164 children (328 hips) aged from three months to five years.
Using regression and correlation analysis, mathematical formulae were derived which allow the calculation of the normal acetabular and centre edge angles for a given age. The relationship between age, acetabular angle and centre edge angle was studied.
Résumé
L'angle du toit du cotyle et l'angle CE ont été mesurés radiologiquement chez 164 enfants (328 hanches) âgés de trois mois à cinq ans.
Grâce aux analyses de régression et de corrélation, on a pu mettre au point les formules mathématiques qui permettent le calcul des angles normaux pour un âge donné. Les rapports entre l'âge, l'angle du toit du cotyle et l'angle CE sont étudiés.
