Fig. 7A–B.

This figure shows a second potential application of the determined reference values for the acetabulum. (A) The AP pelvic radiograph of a 32-year-old male patient is shown. The analysis with Hip²Norm reveals excessive values of all parameters (indicated by darkened boxes) except for the anterior coverage, which was normal. Acetabular overcoverage with a too prominent posterior acetabular rim was diagnosed. (B) The patient underwent surgical hip dislocation with trimming of the posterior and superior acetabular rim. The anterior rim was not addressed surgically. This led to normalization of most of the parameters.
