Background. The present study evaluated some anatomical characteristics of the acetabulum and proximal femur in the hips of adult asymptomatic Vietnamese individuals. Methods. We used 32 slice computed tomographic system with a multiplanar reconstruction (MPR CT) protocol to evaluate several parameters of the acetabulum and proximal femur, including Acetabular diameter (ADi), Acetabular depth (ADe), Acetabular ratio (AR, calculated by (ADe/ADi) x100), Acetabular inclination angle (AI), Acetabular anteversion angle (AA), Centre-edge angle (CE), Femoral head diameter (FDi), Femoral neck anteversion (FA), Combine anteversion angle (CA, calculated by AA + FA), Femoral shaft-neck angle (SN), and Femoral medial offset (FO). Results. The average of parameters of ADi, ADe, AR, AI, AA, CE, FDi, FA, CA, SN, FO were 50.0 ± 2.9 mm; 24.3 ± 2.2 mm; 48.5 ± 3.7 mm; 38.5 ± 3.9°; 17.2 ± 7°; 38.3 ± 6.4°; 44.4 ± 2.9 mm; 13.7 ± 10.4°; 30.8 ± 13.2°; 129.5 ± 5.8°; 32 ± 4.9 mm, respectively. There were no significant differences between the sexes in ADi (P < 0.001), ADe (P < 0.05), FDi (P < 0.001). Males had significantly larger acetabula and femoral heads. There was evidence of a statistically significant negative association between age and ADi, FDi, SN (P < 0.05). There was evidence of a statistically significant positive association between ADi and ADe (P < 0.001), ADi and FDi (P < 0.001), AI and CE (P < 0.05), SN and FO (P < 0.001). Conclusion. There are marked quantitative differences between hip joint parameters of healthy adult Vietnamese individuals and what is reported in other ethnic groups. These data constitute a baseline for future research related to hip joint pathology and hip joint replacement surgery in Vietnamese subjects. [ABSTRACT FROM AUTHOR]
