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[edit | edit source]
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[edit | edit source]
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[edit | edit source]
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.
