【 摘 要 】

BackgroundPost-traumatic tibial osteomyelitis is considered as complex clinical problem due to its unique characteristics such as prolonged course, multi-staged treatment and high recurrence rate. The purpose of this study is to identify and analyze the causes and risk factors associated with infection recurrence of tibial osteomyelitis treated with Ilizarov technique.MethodsFrom January 2011 to January 2019, a total of 149 patients with post-traumatic tibial osteomyelitis treated with Ilizarov bone transport technique were included in this study. Demographic and clinical data were collected and analyzed. Univariate analysis and logistic regression analysis were used to analyze the factors that may affect the recurrence or reinfection of post-traumatic tibial osteomyelitis after treated with Ilizarov bone transport technique.ResultsAll included patients were successfully followed up with an average of 37.5 month (18–78 month), among them, 17 patients (11.4%) occurred with recurrence or reinfection of tibial osteomyelitis in which 2 cases were in distraction area and 15 cases in docking site. Among them, 5 patients were treated successfully with appropriate intravenous antibiotic, the remaining 12 patients were intervened by surgical debridement or bone grafting after debridement. Univariate analysis showed that Pseudomonas aeruginosa infection, bone exposure, number of previous operations (> 3 times), blood transfusion during bone transport surgery, course of osteomyelitis > 3 months, diabetes was associated with recurrence or reinfection of postoperative tibial osteomyelitis. According to the results of logistic regression analysis, Pseudomonas aeruginosa infection, bone exposure, and the number of previous operations (> 3 times) are risk factors for recurrence or reinfection of posttraumatic tibial osteomyelitis treated with Ilizarov bone transport technique, with odds ratios (OR) of 6.055, 7.413, and 1.753, respectively.ConclusionThe number of previous operations (> 3 times), bone exposure, and Pseudomonas aeruginosa infection are risk factors for infection recurrence of posttraumatic tibial osteomyelitis treated with Ilizarov bone transport technique.
