Background: Although delays in musculoskeletal care in low- and middle-income countries (LMICs) are well documented in the open fracture literature, the impact of surgical delays on closed fractures is not well understood. This study aimed to assess the impact of surgical delay on the risk of infection in closed long-bone fractures treated with intramedullary nailing in LMICs.
Methods: Using the SIGN (Surgical Implant Generation Network) Surgical Database, patients ≥16 years of age who were treated with intramedullary nailing for closed diaphyseal femoral and tibial fractures from January 2018 to December 2021 were identified. Infection was diagnosed based on the assessment by the treating surgeon. A logistic regression model, adjusting for potential confounders, was used to analyze the association between delays to surgery (in weeks) and infection.
Results: Of the 9,477 closed fractures that were included in this study, 58% were femoral fractures and 42% were tibial fractures. The mean age was 35 years, and 76.2% of the patients were men. The mean delay to surgery was 10.5 days, and the median delay to surgery was 6 days. The overall infection rate was 3.1%. The odds of developing an infection increased by 9.2% with each week of delayed surgical treatment (odds ratio,1.092; 95% confidence interval, 1.042 to 1.145). Increasing delays were also associated with longer surgery duration and higher rates of open reduction.
Conclusions: Surgical delays in LMICs were associated with an increased risk of infection in closed long-bone fractures. This study quantified the increased risk of infection due to delays in receiving care, highlighting the importance of timely surgery for closed fractures in LMICs.
