Delay in Initial Debridement for Open Tibial Fractures and Its Possible Impact on Patient Outcomes: A Single-Center Prospective Cohort Study.

Abstract

Background:The current consensus regarding the management of open fracture indicates that the initial debridement should be performed within the first 6 hours after injury. Unfortunately, in Pakistan, the emergency medical services are not well-established and patient arrival at the hospital is delayed the majority of the time. In this study, we present our experience with delayed surgical management of open tibial fractures.Methods:A prospective study of patients who presented to the accident and emergency department of the authors’ institution was performed. The duration of the study was 4 years. All patients ≥18 years of age with an isolated open fracture of the tibia were included in the study. Open fractures were graded using the Gustilo-Anderson (GA) classification. The study participants were divided into 3 groups based on the timing of the surgery. Infection and nonunion rates were compared using chi-square analysis. P < 0.05 was considered significant.Results:A total of 1,896 patients were included in the study. There was no significant difference between the results of surgery performed before 48 hours and those of surgery performed after 48 hours with regard to the infection rates associated with GA type-I (p = 0.48), type-II (p = 0.70), or type-III (p = 0.87) fractures or the nonunion rates associated with type-I (p = 0.6338), type-II (p = 0.4030), or type-III (p = 0.4808) fractures. A higher GA classification was associated with higher rates of infection and nonunion independent of the timing of the surgery (95% confidence interval [CI] = 1.24 to 1.89, p < 0.01).Conclusions:Our study indicates that the risks of infection and nonunion remain acceptable despite delays in the management of open tibial fractures within a 24 to 96-hour window. A delay in the initial time to debridement is acceptable only when early care cannot be provided. Prompt initial debridement remains the best possible treatment for open tibial fractures.Level of Evidence:Therapeutic Level II.
