Résumé
Many orthopedic surgeries utilize intraoperative fluoroscopy. The mini C-arm is an advantageous device as it can be easily used without the need for a dedicated radiology technician. However, there are concerns that the mini C-arm may represent a potential source of contamination and subsequent postoperative infection. Previous investigations of standard C-arm drapes have shown high rates of contamination. Similar contamination rates would be even more concerning for the mini C-arm as it requires physically maneuvering the machine. This study aimed to determine the rate of mini C-arm drape contamination and identify high-risk areas. Fifty foot and ankle surgeries requiring the use of mini C-arm fluoroscopy were included. Eight locations on the mini C-arm drape were sampled at the conclusion of each procedure. Culture Q-swabs were used for sampling defined locations. Swab samples were then assessed for bacterial growth on a 5% blood agar plate using a semiquantitative technique. In 70% of surgical cases, contamination was observed in at least 1 location. Six of the 8 evaluated locations were found to have significantly higher contamination in comparison with their corresponding negative controls (Mann-Whitney Bacterial contamination of the mini C-arm drape was found to be common after foot and ankle procedures. Contamination was more prevalent on the outer ring areas of the C-arm, both at the emitter and receiver. Level III, prospective cohort study.

BACKGROUND
Many orthopedic surgeries utilize intraoperative fluoroscopy. The mini C-arm is an advantageous device as it can be easily used without the need for a dedicated radiology technician. However, there are concerns that the mini C-arm may represent a potential source of contamination and subsequent postoperative infection. Previous investigations of standard C-arm drapes have shown high rates of contamination. Similar contamination rates would be even more concerning for the mini C-arm as it requires physically maneuvering the machine. This study aimed to determine the rate of mini C-arm drape contamination and identify high-risk areas.

CONCLUSION
CONCLUSIONS
Bacterial contamination of the mini C-arm drape was found to be common after foot and ankle procedures. Contamination was more prevalent on the outer ring areas of the C-arm, both at the emitter and receiver.
