The centre--edge angle of Wiberg in adult Africans and Caucasians. A radiographic comparison.

In an earlier publication (Skirving and Scadden I 979) an anthropometric study of neonatal African hips concluded that the immunity of the African to congenital dislocation was probably related to anatomical factors. The depth of the acetabulum relative to its diameter tended to be deeper in the African than the Caucasian, although the orientation of the acetabulum and the femoral neck was similar in the two groups. It was suggested that a radiographic comparison of the hips of adult African and Caucasians might reveal further evidence of a basic difference in the shape of the hips of the two racial groups.
