title: Three-dimensional computed tomography reconstruction measurements of acetabulum in Chinese adults.
abstract: The present study was designed to define the morphological dimensions of the acetabulum in normal Chinese adults and to statistically compare these data with the available data worldwide. This information is important for the diagnosis of dysplasia and treatment of total hip arthroplasty. In this study, the gender and bilateral differences were evaluated. One-hundred CT scans of patients were retrospectively studied. These individuals showed no signs of developmental disturbances in either of the hip joints. Thirty-five morphometric parameters of the acetabulum were measured. The size of acetabulum was evaluated by the acetabular perimeter, anteroposterior diameter, vertical diameter, the depth and width of fossa ovalis in both transaxial and coronal plane. The parameters of acetabular orientation were the acetabular angle, anterior center edge angle, neck shaft angle, acetabular anteversion, and abduction angle. The coverage of acetabulum was examined as the, acetabular head index, center edge angle, the distance between the femoral head, and acetabulum. Gender and bilateral differences were analyzed for each parameter, and compared with available worldwide data. The results showed statistically significant differences between the Chinese genders and also between the Chinese and other human races in some parameters. In conclusion, gender, bilateral and racial differences exist in the morphology of acetabulum. The data may be helpful for the design of total hip arthroplasty for the Chinese population.
