- Abstract
Background: Proximal femur replacements in patients with sarcoma are associated with high rates of infection. This study is the largest one comparing infection rates with titanium versus silver-coated megaprostheses in sarcoma patients.Methods: Infection rates were assessed in 99 patients with proximal femur sarcoma who underwent placement of a titanium (n = 35) or silver-coated (n = 64) megaprosthesis. Treatments administered for infection were also analyzed.Results: Infections occurred in 14.3% of patients in the titanium group, in comparison with 9.4% of those in the silver group, when the development of infection was the primary end point. The 5- and 10-year event-free survival rates for the prosthesis relative to the parameter of infection were 90% in the silver group and 83% in the titanium group. The overall infection rates were 10.9% in the silver group and 20% in the titanium group. Two patients each in the silver and titanium groups ultimately had to undergo amputation. The need for two-stage prosthesis exchanges (57.1% in the titanium group) declined to 14.3% in the silver group.Conclusion: Using a silver-coated proximal femoral replacement nearly halved the overall infection rate. When infections occurred, it was usually possible to avoid two-stage prosthesis exchanges in the silver group.
