Functional Prosthetic Spacer Surgical Technique for Definitive Management of Hip Periprosthetic Joint Infection

The appropriately sized acetabular polyethylene liner is utilized. If instability is a concern, a dual mobility liner can be utilized. The back side of either chosen liner is scored with a saw or burr. In situations where significant acetabular bone loss is present, screws may be placed in the anterior and/or posterior columns to serve as rebar for the planned cement mantle. The femur is broached sequentially until an adequate fit is obtained. A cemented femoral stem is used primarily. If proximal femoral bone stock is poor, a long-cemented stem is utilized.
