Complications of Open Tibial Fracture Management: Risk Factors and Treatment

Abstract

Open tibial fractures result in high rates of complications. This study aims to elucidate the risk factors causing these complications, and suggest antimicrobial regimens based on the organisms grown in post-operative infections. Over a period of five years, 173 patients had sustained open tibial fractures and undergone operative treatment at a single institution. All surgical data was gathered retrospectively through online medical records. Thirty-one patients (17.9%) had sustained post-operative bony complications, while infective complications were reported in 37 patients (21.4%). Patients with Gustilo type III fractures were found to be more than three times as likely to sustain post-operative infective (p=0.007) or bony (p=0.015) complications, compared to Gustilo type I or II fractures. The fracture location and time taken to fixation did not significantly affect the complication rate, but results were trending towards significance. The commonest cause of infective complications were hospital-acquired organisms, such as Methicillin-resistant staphylococcus aureus (40.5%). Closer monitoring of patients sustaining high grade Gustilo open fractures, as well as antimicrobial prophylaxis for both hospital-acquired organisms and environmental contaminants, will result in the best outcome for patients. Further studies with larger sample sizes are warranted, to determine the significance of fracture location and time taken to fixation on complication rates.
