Total hip replacement surgery in the face of major acetabular bone loss is at high risk of early loosening unless the bone stock is properly reconstructed. Six types of acetabular deficiencies are identified for which unique autograft and allograft techniques are used. These are superolateral, superior, posterior, medial or protrusio, combined or global, and pelvic discontinuity. Several different types of acetabular components can be successfully used in each type. The various acetabular defects encountered are described, along with the current method of reconstruction and case examples.
