An appreciation of the range of normal variation and normal values for the pelvis and hip remains a continuing problem for the orthopedic surgeon in Korea. To help overcome this problem and to provide a comprehensive single source for this information, I have undertaken a study of 1037 unselected Korean subjects (605 normal males and 432 females) who varied in age from newborn to 86 years. The present study is concerned with normal angles and distances of the pelvis and hip, examined roentgenographically for statistical survey from January 1965 to August 1971 at Severance Hospital in Korea.
The results of this study are as follows:
1. The value of the C-E angle, distance h, and distance d is increased according to increment of age but the value of the femoral neck shaft angle, acetabular angle, iliac index and interval of symphysis pubis is decreased with age.
2. ´´The acetabular index in all age groups, iliac angle in the 1-3 months group, C-E angle in the
6-10 months group and the adult group over 18, interval of the symphysis pubis in the 4-22 year group, distance h in the 3-6 months group and the 4-8 year group, and distance d in the 1-3 months group show a difference between males and females.
3. There are differences between normal females and pregnant women in the interval of the symphysis
pubis. Also the degree of relaxation of joints of the pelvis is higher in primigravida than multigravida.
4. The value for the femoral neck shaft angle is higher in Koreans than Europeans.
