Efficacy of antibiotics in low-velocity gunshot fractures

We have investigated the efficacy of intravenous antibiotic therapy as a prophylactic measure to prevent infection following low-velocity gunshot fractures. Ninety-six consecutive patients were randomized prospectively to either an antibiotic group (Group I) or a nonantibiotic group (Group II) and were followed in a special gunshot wound clinic. Only patients with fractures that could be treated by closed techniques and did not require internal fixation were included. Sixty-seven patients (73 fractures) were followed radiographically. At follow-up, 36 fractures in Group 1 and 37 fractures in Group II comprised the study group. A total of two infections, one in each group, was documented. No significant infection prophylaxis was demonstrated by the use of intravenous antibiotics in these injuries.
