Abstract
The anatomy of the posterior wall of the acetabulum is important for the hip stability. We wanted to know whether differences can be observed. On lateral 3D pelvic CT reconstruction of the pelvis two types were identified. On axial CT-images acetabular angles were determined. We observed 35 type I acetabular and 61 type II acetabular. Posterior acetabular sector angle was 114° in type I and 94° in type II acetabular (p < 0.01). At an cut-off angle of 100° we could predict the type of acetabulum. We could describe reference values for the posterior wall to distinguish two morphological types.
