Infected Orthopaedic Implants And Infectious Agents: MRSA Frequency And Infection Patterns, In A Tertiary Care Centre In Central Kerala.
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2017, Vol 2, Issue 6
Abstract
Introduction:- Orthopedic implants have revolutionised treatment of bone fractures and non-infectious dysfunctional painful joint arthritis and have become an essential component of modern medicine. There is also an increasing number of surgeries for trauma related orthopaedic injuries like fractures which often require fixation with an implant which will be retained temporarily or permanently. Infections though uncommon seriously affect patient outcome Objective:- To identify bacteria which cause infections in orthopaedic implants and to study their antibiotic susceptibility pattern with a focus on Gram positive bacterial isolates . Materials and methods:- A Cross sectional study was conducted in patients who had undergone prosthesis or implant surgeries and presenting with signs and symptoms of infections in the orthopaedic department during one year period. Specimens included for the study were pus swabs, pus aspirates, tissue and screws. Identification was based on Gram staining and cultural characteristics as well as biochemical reactions of the isolate using standard laboratory procedures. Results: Among the 105 cases studied, males were 79 % and females were 21% and in 95.2%, the indication for orthopaedic intervention was fracture, only 4.8 % were for arthritis. Among the culture positives for Gram positive bacteria 62 (91.2%), Staphylococcus aureus (MSSA)- 38 was the most common isolate CONS was 13, MRSA constituted 10,and one Enterococcus faecium. Summary and Conclusion: Bone implant infections are associated with significant morbidity for the patient and also adds significantly to healthcare costs. Careful selection of antibiotics for pre-operative prophylaxis, taking into account the common etiological agents in this type of infection could be an important step to prevent its occurrence.
