Aims and Objectives: A prospective study to determine the role of qualitative culture (both pre-debridement and post-debridement) in detecting infection in open fractures, and to highlight any correlation between infection and other variables (age, sex, Gustilo Anderson classification and Ganga Hospital Open Injury score). Material and Methods: One hundred seventy patients with Gustilo-Anderson Grade II, IIIA, B and C Open fractures of long bones came to our hospital and were treated operatively during the study period. Thirty one patients were excluded from the study based on the exclusion criteria. One patient died two days after surgery and three patients were lost to follow up and hence excluded from the study. Finally, 135 patients with 148 open fractures were included in the study and were followed on subsequently for development of infection. Open fractures were classified based on the Ganga Hospital Open Injury Score and Gustilo-Anderson classification. Wound swab was taken from the deeper part of wound and timing of wound swab for cultures were:- First swab in the casualty before IV antibiotic administration; second swab in operation theatre after wound debridement; Third swab was taken in case of wound healing complications eg.-purulent discharge (CDC Criteria for SSI). Result: Overall infection rate in open fracture was 14.2% with 5.2%, 5.7%, 19.8% and 12.5% in Gustilo- Anderson grade II, IIIA, IIIB and IIIC respectively. Pearson coefficient for correlation was 0.677 between GustiloAnderson grading and infection rate where as it was 0.99 between Ganga Hospital Open Injury Group and infection rate. Conclusions: Micro-organisms present in predebridement and post-debridement culture are only contaminating agent and have no role in causing infection. Staphylococcus aureus is the single most common infecting organism followed by Escherichia coli. Overall Gram negative micro-organisms are the most common infecting agent. Finally, Ganga Hospital Open Injury Score is better scoring system in predicting infection in open fractures
