Assessing Outcome of Unreamed Interlocking Intramedullary Nailing in Open Tibial Shaft Fractures – An Observational Study (Code-T0326)

Introduction: Open tibial shaft fractures are common orthopedic injuries that pose challenges in 
management due to their high risk of infection and nonunion. Unreamed interlocking 
intramedullary nailing (ILN) has emerged as a preferred treatment modality for these fractures, 
providing stability while preserving endosteal blood supply. This study aims to evaluate the 
functional and clinical outcomes of unreamed ILN in open tibial fractures. 
Aims and Objectives: The study aims to assess the effectiveness of unreamed ILN in open tibial 
shaft fractures by analyzing fracture healing, functional recovery, and complication rates. It also 
seeks to determine the impact of fracture classification (Gustilo-Anderson) on outcomes. 
Methods: A prospective observational study was conducted on patients with open tibial fractures 
treated with unreamed ILN. Patients were categorized based on the Gustilo-Anderson 
classification. Demographic data, mode of injury, fracture patterns, time to surgery, weight
bearing timelines, and postoperative complications were recorded. Functional outcomes were 
assessed using range of motion (ROM), weight-bearing capacity, and the AO classification 
system. Statistical analysis was performed using chi-square tests and ANOVA. 
Results: The study found no significant association between sex, occupation, mode of injury, or 
fracture side with clinical outcomes. While unreamed ILN resulted in satisfactory union rates, 
functional recovery varied based on fracture severity. Complications such as delayed union and 
superficial infections were observed but were not statistically significant. 
Conclusion: Unreamed ILN is a reliable method for treating open tibial fractures, providing 
good functional outcomes. Early intervention and rehabilitation play a crucial role in optimizing 
recovery.
