The Effect of Treatment Delays on Fracture-related Infection in Open Tibia Shaft Fractures: A Retrospective Cohort Study

Résumé fourni par la source

Background: Controversy remains on the most effective method of treating open tibia shaft fractures. The timing of the different treatment variables remains at the heart of this dispute. This study aimed to investigate outcomes of open tibial shaft fractures. Specific objectives were to determine the association of time delay to antibiotic administration, surgical debridement, definitive skeletal stabilisation and soft tissue reconstruction, and the development of fracture-related infection (FRI). Materials and methods: A total of 227 patients with 237 open tibia shaft fractures were included. The time from arrival to (1) antibiotic administration (<3 hours vs >3 hours); (2) primary debridement in theatre (<24 hours vs >24 hours); (3) definitive skeletal stabilization (<5 days vs >5 days); (4) definitive soft tissue reconstruction (<5 vs >5 days); and (5) time to union was recorded. The number of debridements and the length of hospital stay were also recorded. Results: Patients who waited more than 5 days for definitive skeletal fixation or soft tissue reconstruction had a significant increase in FRI [odds ratio (OR) 4.7, 95% confidence intervals (CI): 2.0-10.9 and OR 4.7, 95% CI: 2.0-11.0, respectively]. Patients who underwent more than two formal debridements also had a higher risk of developing FRI than those who only had ≤2 debridements (OR 15.6, 95% CI: 5.8-41.6). Conclusion: Time delays in managing open tibia shaft fractures are associated with an increased risk of FRI. Definitive soft tissue reconstruction and skeletal stabilisation should not be delayed for more than 5 days. Clinical significance: Fracture-related infection following open tibia shaft fractures can be mitigated by reducing treatment delays, specific to definitive soft tissue reconstruction and skeletal stabilisation.
