Double-metal tantalum cups restored acetabular structure, achieving initial stability without screws.
In a case of a 63-year-old male, severe acetabular bone defect led to a novel reconstruction technique.
The approach involved a staged revision with a focus on optimizing press-fit for improved stability.
Findings suggest significant potential in using double cups for patients with extensive bone loss during hip revisions.
