Abstract
We measured the CE angle, Sharp angle, acetabular roof obliquity and acetabular cover ratio of the femoral head of 62 males and 216 females.
The CE angle was 37±7.2 degrees (mean±SD), the Sharp angle was 36±5.5 degrees, the acetabular roof obliquity was 5.6±5.7 degrees. These values are similar to those of a Caucasian. The anterior acetabular cover ratio was 52±14 percent, the posterior acetabular cover ratio was 79±12 percent.
The CE angle correlated very closely with the posterior acetabular cover ratio. With increasing age, the posterior acetabular cover ratio tended to increase. We assumed that the reason was that the pelvis tilted to the posterior with increasing age.
