Background/Aim. Anatomical parameters of the bony components of the hip joint
are essential for better understanding of etiopathogenesis of diseases like
primary osteoarthrosis of the hip joint. The aim of this reserch was to
examine the normal acetabular morphometry in Serbian population and to
determine whether there are sex differences in anatomical parameters of the
acetabulum among asymptomatic subjects. Methods. Pelvic radiographics of 320
adult asymptomatic patients (640 hips) were analyzed in 170 men and 150 women
to determine the morphology of the acetabulum in Serbian population. For each
hip the center edge angle of Wiberg (CEA), the acetabular angle of Sharp
(AA), acetabular depth (AD), acetabular roof obliquity (ARO) and roof angle
(RA) were measured. Results. The following average measurements for
acetabulum geometry were obtained (X ? SD): CEA - 33.5 ? 6.5? (33.6 ? 5.8? in
male, 33.3 ? 6.9? in female), AA - 38.0 ? 3.8? (37.5 ? 3.6? in male, 38.5 ?
3.9? in female), AD - 11.9 ? 2.8 mm (12.5 ? 2.7 mm in male, 11.2 ? 2.7 mm in
female), ARO - 7.6 ? 5.7? (6.2 ? 4.9? in male, 9.0 ? 6.0? in female) and RA -
18.4 ? 10.0? (19.6 ? 8.5? in male, 17.1 ? 9.5? in female). There were
significant differences in the CEA, AA, AD, ARO and RA related to gender (p <
0.01, t-test). Conclusion. There are significant gender differences in
Serbian population for all the examined anatomical parameters of acetabulum.
We found sex-related differences in acetabular morphology, female acetabulum
being marginally more dysplastic than male acetabulum. There is also a clear
tendency of female hips to be more dysplastic than male ones.
