Revisión acetabular en los defectos óseos severos con cotilos esféricos atornillados recubiertos de hidroxiapatita y homoinjertos óseos fragmentados impactados

For the reconstruction of major acetabular defects, primary screw-in hydroxyapatite-coated cups resting on impacted and morselized allografts can be stable and integrate radiographically without need for full contact with fresh bone.
