Abstract

OBJECTIVES: To evaluate a large series of open fractures of the forearm following gunshot wounds in order to determine complication rates and factors that may lead to infection, nonunion, or compartment syndrome.

DESIGN: Multi-center retrospective review. SETTING: Nine Level 1 Trauma CentersPatients/Participants: 168 patients had 198 radius and ulna fractures due to firearm injuries. All patients were adults, had a fracture due to a firearm injury and at least one year clinical follow-up or follow-up until union. Average follow-up was 831 days. INTERVENTION: Most patients (91%) received antibiotics. Formal irrigation and debridement in the operating room was performed in 75% of cases along with either internal fixation (75%), external fixation (6%), or I&D without fixation (19%). MAIN OUTCOME MEASURES: Complications including neurovascular injuries, compartment syndrome, infection and nonunion.

RESULTS: Twenty-one percent of patients had arterial injuries and 40% had nerve injuries. Nine patients (5%) developed compartment syndrome. Seventeen patients (10%) developed infections, all in comminuted or segmental fractures. Antibiotics were not associated with a decreased risk of infection. Infections in the ulna were more common in fractures with retained bullet fragments and bone loss. Twenty patients (12%) developed a nonunion. Nonunions were associated with high velocity firearms and bone defect size.

CONCLUSIONS: Open fractures of the forearm from gunshot wounds are serious injuries that carry high rates of nonunion and infection. Fractures with significant bone defects are at increased risk of nonunion and should be treated with stable fixation and proper soft tissue handling. Ulna fractures are at particularly high risk for deep infection and septic nonunion and should be treated aggressively. Forearm fractures from gunshot wounds should be followed until union to identify long term complications. LEVEL OF EVIDENCE: Prognostic Level III.
