Abstract:
PURPOSE: The authors measured the anteversion of the femoral neck and acetabulum and the sum of the two values in normal Korean people by computed tomography. The authors examined the normal range of the values to analyze the difference in sex and sides as well as the relationship between the femoral neck and acetabular anteversion. MATERIALS AND METHODS: The authors measured the anteversion of the femoral neck and acetabulum in 118 normal Korean adult males and 114 females aged between 21 and 49 on both the right and left sides by computed tomography and calculated the sum of anteversion. The authors analyzed the mean and standard deviation, and investigated the sex differences and side differences, as well as the relationship between the acetabular anteversion and femoral neck anteversion statistically. RESULTS: The anteversion of the acetabulum in males was 15.3°±6.1° on the right side and 15.3°±6.6° on the left side. The anteversion of the femoral neck in males was 5.3°±7.6° on the right side and 1.5°±9.2° on the left side according to the Hernandez et al. method. The anteversion of acetabulum in females was 16.8°±5.4° on the right side and 16.3°±5.8° on the left side. The anteversion of femoral neck in females was 10.3°±8.2° on the right side and 7.9°±8.2° on the left side according to Hernandez et al. method. No difference in acetabular anteversion, and a significant difference in the femoral neck anteversion on both the right and left sides were observed between males and females. No difference of acetabular anteversion was observed between the right and left sides, but a significant difference in femoral neck anteversion was noted between the right and left sides measured by either the Hernandez et al. method or Weiner et al. method. The Pearson coefficient revealed no correlation between the femoral neck anteversion and acetabular anteversion. CONCLUSION: No difference in the acetabular anteversion was observed, but there was a significant difference in femoral neck anteversion between males and females. A significant difference in femoral neck anteversion was observed between the right and left sides. No correlation was noted between the anteversion of the femoral neck and acetabulum.
