Objective: To measure the depth of acetabulum [the Centre edge (CE) angle] in adult normal Jordanian population. Design: Descriptive Case -Series Study.Participants: Antero -posterior (AP) radiographs of (400 hips) taken for adult nonorthopedic patients of various age groups, 105 were men and 95 were women. Main Outcome Measurements:The centre -edge (CE) angles of 400 hips were measured by Wiberg method.Results: The (CE) angle increased with age. There is no significant difference between men and women, nor is a significant difference between right and left. The distribution of (CE) angles is similar to other studies in Indians, Caucasians and Africans. Conclusion:The acetabular depth measured by the (CE) angle (acetabular dysplasia) could not be the main factor in etiology of osteoarthritis and congenital dislocation of the hip.
