Abstract:

〔Abstract〕 Objective： To investigate the risk factors and treatment methods of early incision deep infection after posterior lumbar internal fixation and fusion. Methods： The case data of patients undergoing posterior lumbar internal fixation and fusion in the Department of Orthopedics of the First People's Hospital of Yunnan Province from January 2010 to December 2018 were retrospectively analyzed， and all patients were assessed for risk factors for infection（RFS）. The patients were divided into non-infection group（n=1 481） and infection group（n=11） according to whether or not patients have an infection. The patients in the infection group were treated with thorough debridement， closed irrigation and drainage， and antibiotics. Results： The difference in RFS between the two groups was statistically significant（P＜0.05）. In the infection group， 6 cases were cured after debridement， closed irrigation and drainage and antibiotic treatment， 1 case died of incision infection complicated with intracranial infection， and 4 cases were cured of infection after repeated debridement， closed irrigation and antibiotic treatment to remove internal fixator. Conclusion： The incidence of early incision infection after posterior lumbar internal fixation and fusion is low， and thorough debridement， closed irrigation and drainage and antibiotic therapy can cure infection； the internal fixator should be removed after thorough debridement for patients with long-term oral corticosteroids and RFS>3 points.
