Wiberg's 1953 paper formalizes the CE (center-edge) angle as the radiographic tool for quantifying acetabular coverage in adults and children. It then reports outcomes of the shelf acetabuloplasty in 85 hips with dysplasia, subluxation, and dislocation. The paper answers two questions: how do we measure the problem, and when should we operate?
