Are Custom Triflange Acetabular Components Effective for Reconstruction of Catastrophic Bone Loss?

Although the introduction of ultraporous metals in the forms of acetabular components and augments has increased the orthopaedic surgeon's ability to reconstruct severely compromised acetabuli, there remain some that cannot be managed readily using cups, augments, or cages. In such situations, allograft-prosthetic composites or custom acetabular components may be called for. However, few studies have reported on the results of these components.
