Abstract
Introduction: The tibia shaft is a common site for bone fractures and open fractures. Tibia shaft fracture is mostly caused by high-energy trauma such as a fall from a height or a road traffic accident. The objective of this study was to evaluate the treatment outcome of tibia shaft fracture managed by close reduction and internal fixation with interlocking Intramedullary Nails (IMN) and to determine factors that are associated with tibia fracture infection. Methods: This retrospective study was conducted at the Emergency Trauma Hospital, Freetown, Sierra Leone. We analyzed the medical records of a mixed cohort of patients who were treated for, tibia shaft fracture by closed reduction and internal fixation with interlocking intramedullary nails for the period January 2020 to January 2022; with at least 15 months of follow-up. We later used both bivariate and multivariate logistic regressions to determine the factors that are associated with wound infection post-internal fixation. Results: A total of Ninety (n = 90) patients’ medical records were reviewed of which 79 were included for analysis. The median age was 30 years (Inter Quartile Range: 16-67 years). The average hospital stay was 20 days (Inter Quartile Range: 6-156 days). The mean fracture nailing time was 11 days. Infection and non-union rates were at 18.99% and 3.8% respectively. Type of tibia shaft fracture (AOR = 25.51, 95% CI = 2.06-422.75,) and characteristics of wound (AOR = 29.51, 95% CI = 2.06-422.75) were significantly associated with wound infection. The treatment outcome categorization of IMN was successful in 88.61% of the patients. Conclusion: This study concludes that the type of tibia shaft fracture and characteristics of the wound are major predictors of wound infection. The findings of this study suggest that IMN fixation of closed and Gustilo type 1 Tibia shaft fracture led to successful healing in the majority of the cases with a low non-union rate.
