Salvage of acetabular insufficiency with cementless components.
In conclusion, it appears that large outside-diameter bipolar devices or threaded, cement-free acetabular components (with or without porous surfaces) provide excellent hip stability when used to salvage hips with acetabular insufficiency. The bipolar or threaded devices can maintain or restore normal or nearly normal hip mechanics, minimize pain by preventing motion between the cup and the bone, and permit fill-in of bony defects and healing of nonunited fractures. Both grafting should be used whenever possible, since it may prevent medial migration and allow for replacement with a cemented or cementless porous-surfaced cup in the future should pain occur. A cane or crutch should be used to minimize stress across the joint and thereby prolong the life of the reconstruction. All patients must realize that these are salvage procedures.
