The hip bone has two surfaces (lateral and medial) and is bounded by four margins (anterior, posterior, superior and inferior). The classification and subsequent treatment of acetabular fractures are based on imaging studies that have been derived from a thorough understanding of the anatomy of the innominate bone [17, 18, 19].
