Custom 3D-printed porous titanium augments for Paprosky type III acetabular defects: a case series combining biomechanical rationale with early clinical outcomes

Personalized 3D-printed porous titanium alloy augments demonstrate favorable biomechanical safety and clinical efficacy based on FEA and initial case review. For severe acetabular bone defects, these custom augments offer good initial stability, promoting bone integration for long-term fixation, and potentially reducing risks associated with cup loosening, dislocation, and periprosthetic fracture.
