title: [The significance of the center-edge angle in the prognosis of the dislocated hip 50 years after its initial description by Wiberg].
abstract: In a small child, the prognosis of hip dysplasia is determined most of all by the quality of the covering over the femoral head. A simple radiometric expression of the extent repositioning has been achieved is Wiberg's CE angle (1939). It is suggested that a new classification be established for the critical area: between 10 degrees and 20 degrees. Other criteria for evaluating dysplasia of the hip are suitable for establishing the prognosis--assuming they include the socket; however, their application is often more complicated. Deformation of the femoral head, the CCD angle, and antetorsion of the femoral head are less suitable predictors. In the 100 patients with uni- or bilateral CDH, the long-term follow-up (mean of 47 years), indicates that there is an extraordinarily high incidence of arthrosis.
