Introduction: Tibial fracture is one of the commonest bony injuries associated with increasing number of road traffic accidents in developing countries. The long bone contains long medullary canal & have a subcutaneous position. Reaming of medullary canal may increase the chances of fat embolisms syndrome & increase the inflammatory response. Controversy prevails between reaming & unreaming of the medullary canal as considered the fracture union, ease & short surgical time & systemic complications. Objective: The objective of the study is to evaluate the results of short surgical time & unreamed vancomycin dipped tibia interlocking nail surgery in hanging leg position for tibia fractures. Material & Methods: In this study total (n= 49) cases of tibia fracture who underwent unreamed tibia nailing were evaluated retrospectively. Among (n=49) cases (n= 35) 71% were males & (n=14) 29% were females. According to Ellis classification (n=20) patients had mild, (n=25) patients had moderate & (n=4) patients had severe variant. Results: In the study total number of cases with tibia fracture included where commonest mode of injury was vehicular accident (n=40) (82%) and fall from height (n=9) (18%). Patients who were operated late had associated injuries that prevent early operation. Rust score was used for radiological union score. Mean value of rust score for this study was 8.8 with Inter observer agreement among all three reviewers was substantial, with ICC=0.78(95% CIs 0.65-0.90). Follow-up duration varied from 1 to 6 months with one patient had infection at surgical side and went for debridement and intravenous antibiotics for recovery. Conclusion: Unreamed interlocking tibial nailing can be safely used for type-I and type-II open injuries even with delayed presentation. Compared to reamed nail there is ease of technique application and the decreased operative time in unreamed interlocking nailing.
