Objectives: Orthopaedic implants associated infections are the major problem of surgical site infection, lead to high morbidity and mortality. They are preventable if its risk factors, causative organisms and antimicrobial susceptibility patterns in the regional area are timely recognized. Aim: This study is aimed at determining prevalence, risk factors and bacterial profile of orthopedic implants associated infection. Methods: This was a cross sectional study. The study group comprised of 90 patients who had undergone orthopaedic prosthetic implant surgeries and presented with signs and symptoms of infections. The demographic data were recorded and all related risk factors were noted. Samples are taken from the infection site and processed in the laboratory for identification on microorganism as per the standard protocol. Results: The prevalence of implants associated infection was 25.7% (90/350). Majority of the patients were 45-60 years predominantly male. Interlocking nails and dynamic compression plates were the most common used implants. Obesity, smoking, duration of the surgery, pre-operative blood transfusion and prolonged duration of hospital stay were the significant risk factors associated with the infections. Among overall isolated organism 60.1% was Gram negative bacilli and 39.9% were Gram-positive cocci Staphylococcus aureus (25.5%) was the predominant isolate followed by pseudomonas (15.5%), Klebsiella (12.3%) and Coagulase Negative staphylococci (11.1%). Conclusion: obesity, smoking, duration of surgery and post-operative hospital stay were the significantly associated risk factors and Staphylococcus aureus was the most frequent isolates in orthopedic implants associated infections.
