The Hilgenreiner line is a line drawn horizontally through the inferior aspect of both triradiate cartilages. It should be horizontal, but is mainly used as a reference for Perkin line and measurement of the acetabular angle.
Use of this line with the other lines and angles is used to diagnose developmental dysplasia of the hip (DDH).
History and etymology
It is named after the German surgeon Heinrich Hilgenreiner (3 November 1870 - 24 October 1954).
