Harris classification (acetebular fracture)

The Harris classification of acetabular fractures is based on definitions of acetabular walls and columns that differ from the Judet and Letournel classification ¹.

Usage

The Judet and Letournel classification is more widely used and is applicable to both CT and plain radiographs, whereas, the Harris classification is applicable to CT only ^2,3.

Classification

The Harris classification defines acetabular fractures in four categories ^1,2:

category 0: anterior wall or posterior wall only
category 1: single-column fractures
category 2: both columns (i.e. transverse)
- 2a: no extension
- 2b: superior extension
- 2c: inferior extension
- 2d: superior and inferior extension
category 3: acetabular dissociated from the axial skeleton
