Abstract

Two-stage exchange with implantation of atemporary spacer is the gold standard treatment for chronic periprosthetic joint infection of the hip. This article describes asimple and safe technique for handmade spacers at the hip. Periprosthetic joint infection of the hip. Septic arthritis of the native joint. Known allergy against components of polymethylmethacrylate bone cements. Inadequate compliance for two-stage exchange. Patient unfit to undergo two-stage exchange. Bony defect situation at the acetabulum impeding stable reduction of the spacer. Bone loss at the femur jeopardizing stable fixation of the stem. Soft tissue damage with need for plastic temporary vacuum-assisted wound closure (VAC) therapy. Tailoring bone cement with antibiotics. Preparation of ametal endoskeleton. Molding of spacer stem and head by hand. Customizing spacer off-sets to bony anatomy and soft tissue tension. Implantation assuring rotational stability at the femur with abone cement collar. Confirmation of correct position by intraoperative radiography. Restricted weight-bearing. Range of motion as possible. Reimplantation after successful treatment of infection.
