Introduction: The use of allografts carries the risk of various complications. Among the most frequent is infection. An important risk factor for infection with the use of bone grafts is the transmission of germs through the graft itself. Our objectives are to determine if there is a relationship between possible contamination of the grafts from this bank and postoperative infections; demonstrate how the proper donor selection, procurement, and processing of the graft decrease the rate of contamination; and report other complications related to the quality of the graft. Materials and Methods: We selected patients who received structural bone grafts from our bank. All grafts were microbiologically studied. A review of the health records, anamnesis, physical examination, and radiographs was performed to evaluate infection and other complications. The ISOLS Osseointegration Scale was used to assess the consolidation of the grafts. Results: No graft contamination was detected. One case (7.7%) of infection by carbapenemase-producing Klebsiella pneumoniae (KPC) and 3 cases (23%) of nonunion were identified. Consolidation was good to excellent in 77% of cases, satisfactory in 8%, and poor in 15%. No other complications were found. Conclusion: There is a risk for infection transmission with structural allograft. Regulated donor selection criteria and control of bone bank procedures reduce the risk of infection due to graft contamination and other complications related to graft quality.
