This study compared the efficacy of
antibiotic impregnated beads with conventional intravenous
antibiotics in the treatment of
open fractures. A randomized prospective study was designed and conducted during a 29-month period. Sixty-seven patients with 75
open fractures were treated similarly, with the exception of the method of
antibiotic administration, and were followed up for at least 1 year after injury.
Infection occurred in two of 24 (8.3%) fractures treated with
antibiotic beads alone and in two of 38 (5.3%) fractures treated with conventional intravenous
antibiotics. In an unanticipated nonrandomized third cohort group, patients received
antibiotic beads and intravenous
antibiotics administered for nonorthopaedic reasons or limb threatening injury, or both. Two of 13 (15.4%) fractures in this high risk group became infected.
Infection ultimately resolved in all fractures treated with
antibiotic beads alone or
antibiotic beads in conjunction with conventional intravenous
antibiotics. This study was unable to achieve statistical significance; however, the data suggest
antibiotic beads may be useful in preventing
infection in
open fractures. Thus, a larger multicenter randomized prospective study of isolated
open fractures, eliminating other variables, is justified.
