Two-stage arthroplasty using functional temporary prosthesis to treat infected arthroplasty and septic arthritis of the hip

AimsThis study introduced a modified technique in two-stage revision arthroplasty to insert functional spacer using modular components coated with antibiotic-impregnated polymethylmethacrylate.MethodsSince June 2006, we used the construct in twenty-three consecutive patients (17 with infected arthroplasty, and 6 with septic arthritis of the hip).ResultsMean follow-up was 48 months (range 30–84 months). Two patients were excluded (no second stage), two patients had persistent infection, 19 patients received successful re-implantation at the second-stage.ConclusionThe technique provides a construct that can be used safely and successfully as a functional, spacer in two-stage revision arthroplasty.
