The concept

The concept of this website is based on a previous site that was founded in 2008 and is still up and running. The website is composed as a book, where all sources are properly referenced, according to a good practice in scientific publications.

    Classification of acetabular fractures by Harris and Coupe

    Harris and Coupe classification was published in 2004. It is based on axial CT images of pelvis and has four basic types. Type II has four subtypes.

    Types Description
    Type 0 Wall fracture - limited to the posterior and posterosuperior or anterior wall component of the columns
    Type I Single column fracture - limited to only anterior or posterior column, may extend superiorly or inferiorly from the acetabulum
    Type II Two column fracture - simultaneous involvement of anterior and posterior column
    Subcategory by extension:
    IIA: none
    IIB: superior
    IIC: inferior
    IID: superior and inferior
    Type III Floating acetabulum: articulating surface is detached from the axial skeleton
