Hilgenreiner's line

Hilgenreiner's line is a radiographic measurement used in the diagnosis and monitoring of hip dysplasia. It was named after German pediatrician Heinrich Hilgenreiner.

Overview

Hilgenreiner's line is drawn horizontally through the triradiate cartilages of both hips on an anteroposterior radiograph of the pelvis. It serves as a reference line for other measurements, such as the Perkin's line and the acetabular index.

Usage

In the context of hip dysplasia, Hilgenreiner's line is used to assess the vertical orientation of the acetabulum. The acetabular index is the angle between Hilgenreiner's line and a line drawn from the acetabular roof to the triradiate cartilage. An increased acetabular index is indicative of hip dysplasia.

History

The line was named after Heinrich Hilgenreiner, a German pediatrician who made significant contributions to the field of pediatric orthopedics. He introduced the line as a tool for diagnosing and monitoring hip dysplasia in children.
