[Aspects of dysplasia of the hip-joint, clinically and radiologically, 2nd communication: Remarks on clinical signs and average values of the acetabular angle during the first 3 months].

1. It is not very likely that all degrees of dysplasia of the hip-joint can be discovered with the Ortolani- or snap phenomenon. The definition of these phenomena which presumes a wideining of the acetabulum is against it. Slighter and medium degrees cannot be discerned. All aigns and symptoms however discrete have to be taken into consideration. 2. The average values and standard deviations for the acetabular angle are not sufficiently established statistically for the first 2 months. They cannot, therefore, be used.
