Management of infected bulk allografts with antibiotic-impregnated polymethylmethacrylate spacers.
Twenty-seven patients developed infection following bulk allograft transplantation and were treated with resection of the allograft, placement of an antibiotic-impregnated polymethylmethacrylate (PMMA) spacer, and intravenous antibiotics. Overall, the infection was eradicated in 14 (52%) of 27 patients. Of the 11 patients who did not undergo allograft reimplantation, 5 underwent amputations for persistent infection in the presence of the spacer and 4 had a retained spacer at most recent follow-up. No significant correlation was noted between successful eradication of the infection and age, sex, diagnosis, adjuvant therapy, acute or chronic infection, number of operative procedures, type of allograft procedure, duration of antibiotics, or type of organism. Although deep infection of allograft transplantations continues to result in a high rate of failure, this method of management results in successful limb salvage in almost half of the patients.
