Context: Implant surgery has become one of the most common orthopaedic operations in modern era because of the success of this procedure in restoring function of the affected joint. But orthopaedic implant infections are increasing because of their morbidity and their tendency for serious relapses. Diabetic patients are at high risk for adverse effects following surgery. As the prevalence of diabetes mellitus in people is expected to increase, the number of diabetic patients who undergo orthopaedic surgeries should be expected to increase accordingly. Thus the glycemic control in diabetic individuals has a significant impact on the post-operative outcome. The goal of the present study was to evaluate the role of controlled diabetes on implant infections in orthopaedics. Meanwhile the incidence rate of implant infection was studied as well and as we studied the different micro-organisms isolated from implant infected site.
Aims: To study the role of controlled diabetes on implant infections; to study incidence of infection among patients who have undergone implant surgery. And to study different micro-organisms isolated from the implant infected sites.
Materials and Methods: A total of 40 subjects were included in the study. The study group (n=20) consisted of 20 individuals who were diabetic but their sugar levels were under control with infected implant. The control group (n =20) consisted of healthy individuals who are non-diabetic with infected implant. The HB1AC, Fasting blood sugar (FBS) and post-prandial blood sugar (PPBS) levels were assessed. During surgery, three to five tissue specimens were collected for microbiological and one for histopathological examination. The results were statistically analyzed using Independent t-test.
Results: The data analysis revealed that the control and study group showed significant difference in the HB1AC, FBS, PPBS levels. The range of age in the present study varied from 67 years to 37 years; with the mean age of 50 years in control group and 51years in study group.
In the control group, out of 20 patients, 16 were male and 4 were female. In the study group, out of 20 patients, 13 were male and 7 were female. The incidence rate of implant infection during this study was found to be 3.54%. Staphylococcus aureus (25%)was the most common isolate in implant infections followed by Pseudomonas species (18%), Enterobacter (12%), Acinetobacter species (9%).
Conclusion: The present study showed that controlled diabetes had a negative impact on implant infections compared to non- diabetic patients. The incidence rate of implant infection during this study was found to be 3.54%. Staphylococcus aureus (25%)was the most common isolate in implant infections followed by Pseudomonas species (18%), Enterobacter (12%), Acinetobacter species (9%).
Key words:Implant infections, controlled diabetic patients, and Non-diabetic patients.
