[Acetabular Revision: Reconstruction of Cavitary and Segmental Defects with Special Consideration of Modular Highly Porous Acetabular Revision Systems].

Due to the increasing number of primary hip arthroplasty procedures, revision surgery will be an increasing challenge. The surgeon is frequently confronted with important acetabular defects. Careful preoperative planning is essential to achieve functional and long-term success. Treatment options include porous hemispheric cups, porous metal augments, oblong cups, cemented implants, rings, allografts, patient specific implants and component combinations. In addition to large hemispherical cups, modular porous metal revision systems are increasingly being used to treat severe acetabular bone loss. This article provides an overview of relevant literature and implant-specific features of different reconstruction strategies. Georg Thieme Verlag KG Stuttgart · New York.
