Acetabular Reconstruction Using Massive Allografts for Combined Cavitary and Segmental Defects

Acetabular reconstruction in cavitary, segmental defects and pelvic discontinuity is a technically challenging surgical procedure. Today in orthopaedic surgery there are some available solutions to face this challenge: acetabular reinforcement devices with morselized or bulk grafts, Jumbo hemispherical cups, oblong or bilobed-shaped cups and anti-protrusio cages with morselized bone graft. In this manuscript we described two cases of pelvic discontinuity treated with bulk bone grafts and hemispherical press-fit cups in our Institution.
