Abstract
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.
Highlights
Periprosthetic joint infection (PJI) of the hip has been treated with two-stage revision arthroplasty with success
One-stage revision arthroplasty with a functional antibiotic cement spacer has been used to treat of PJI of the knee with success, while avoiding complications and cost associated with prefabricated and manufactured spacers
With the steady increase in total hip arthroplasty (THA) performed annually in the United States, effective hip PJI management is of paramount importance [3,4]
Summary
Periprosthetic joint infection (PJI) of the hip has been treated with two-stage revision arthroplasty with success. Concerns with this treatment approach include significant morbidity, cost, and functional impairment for the patient. One-stage revision arthroplasty for PJI is commonly performed outside of the United States. The gold standard for definitive chronic PJI is two-stage revision arthroplasty [5]. This treatment is associated with significant morbidity, cost, and functional impairment for the patient [5,6,7,8,9]. Appealing, prefabricated manufactured antibiotic molds and spacers are attributed with limited patient function, greater theoretical risk of mechanical failure and significant cost [13,14,15,16,17]
