Introduction: Tibia is the most fractured long bone in the body. Not only are these fractures relatively common, but they are often difficult to treat. The subcutaneous location of the antero- medial surface of the tibia means that severe bone and soft tissue injury is not infrequent, and there is a high incidence of open fractures compared with other long bones. The use of external fixator has been popular since the 1970s and 1980s and it continues to be used for severe open fractures in the belief that the incidence of infection is less, as there is no metal implant across the fracture site and that the technique is associated with less vascular damage in tibia that are already compromised Material and Method: In this study 25 patients with open fractures of both bones of the leg will be included. All the cases will be treated at Department of Orthopaedics, Guru Nanak Dev Government Hospital, Amritsar and will be followed for about 9 months. Inclusion Criteria: Compound diaphyseal fractures of tibia (Type II, Type IIIa,b) as classified by Gustilo-Anderson grading Results: Out of 25 cases 5 cases showed excellent results, 8 showed good results, 5 showed fair outcome, 7 showed poor outcome. 2 cases ended with amputation. Non union seen in 4 cases, and malunion in 7 cases. Conclusion: External fixation is a good means of immediate fixation for grade 2 and grade 3 open fractures and helps in wound care without disrupting the vascular supply of an already compromised bone.
