Periprosthetic infections occur with an incidence of less than 1% of patients but nevertheless are a serious complication of hip arthroplasties [1,2]. When early infections occur, within 4 weeks of implantation, the implant can be left in place with a high probability of cure whereas late infections require prosthesis revision to eradicate the infection [3,4]. In such cases, one can differentiate between onestage and twostage revisions. In the former a new prosthesis is implanted immediately after the removal of all foreign material in one operation. Twostage revision involves an initial operation to remove all foreign materials and this is followed by an interim phase of 6 – 10 weeks, either left as a Girdlestone situation or with the implantation of a cement spacer. Individual aspects of both forms of revision have been treated very differently in the past so, in the following paragraphs, the different concepts are summarized and their respective ad-vantages and disadvantages discussed.
