초록

Purpose: The purpose of this study is to report the results of culture test at the time of removal of metal devices used for management ofankle fractures and for analysis of contributing factors.
Materials and Methods: We reviewed medical records of 132 patients with lower tibia and ankle fracture who had their metal devicesremoved during the period from January 2010 to February 2014. Patients with clinical signs of infection were excluded. Culture test wasperformed by taking the granulation tissue around the metal device at the time of removal. We divided the subjects into two groups, culturepositive and negative. We then performed a retrospective review of each medical record of multiple factors that might contribute tothe culture results, including laboratory results, medical history, material and size of metal device, indwelling period, and whether or notit was open injury.
Results: Among 132 cases, six were culture positive. Enterococcus was detected in two cases and the others were Staphylococcus. Nosignificant difference in medical history of patients and laboratory results, including C-reactive protein level, was observed between theculture positive and negative group. Culture positive rate was 5.4% in titanium and 3.9% in stainless steel. In terms of metal size, culturepositive rate was 5.1% in small plates, 6.7% in large plates, and culture negative in intramedullary nails. The average indwelling period ofmetal device was 61.5 weeks in the culture positive group, and 68.6 weeks in the negative group. Nine cases were open fractures and allwere in the culture negative group.
Conclusion: Whether or not the culture result was positive, there were no meaningful contributing factors. Presence of bacterium onthe metal device could not be screened by any laboratory results or other factors.
