Abstract:
The aim of investigation is to calculate the mean value of the acetabular anteversion of normal Korean adult after closure of growth according to different gender and sex age group, to find out any significant difference of the value of acetabular anteversion to some other variables such as age, height, weight and radiographic inclination(abduction angle) of acetabulum. Transverse pelvic computed tomography(CT) scans of 360 right hips with no known pathology were examined. The study population consisted of 12 groups by gender (male and female) and age(from third to eighth decade). The number of each group was thirty. The scanning slice nearest the middle region of the acetabulum (nearest through the center of the femoral head) on the scout film was chosen. A measuring point was assigned at the anterior edge of the acetabulum and second at the posterior edge. The line connecting these points was drawn. The angle formed by this line and the plane sagittal to the pelvis was determined as acetabular anteversion. The data analysis was run on a statistical analysis system(SAS). The mean value of acetabular anteversion 19.8±5.4 degrees(17.1±5.6 in males, 22.2±5.4 in females), it was greater significantly in females than in males (p=0.0001). The mean value of acetabular anteversion in third decade male group than the third, fourth and fifth decade group significantly(p < 0.05). The mean value of acetabular anteversion of Koreans was similar to Caucasians value. The value of acetabular anteversion was relatively releated to age. In conclusion, the acetabular anteversion of Korean females was larger than the Korean males. It was increased with aging. When we perform the total hip arthroplasty and pelvic osteotomy or reorientation procedure, we must consider the acetabular anteversion by different gender and age group.
