Abstract
Background The purpose of this study was to evaluate the clinical effect of antibiotic cement-coated locking plate as temporary internal fixation for the treatment of long bone infection in lower extremities . Methods Retrospective analysis the clinical data of 183 patients with lower extremities long bone infection admitted to our hospital from January 2013 to December 2017. All patients were treated with locking plate internal fixation after primary debridement. Antibiotic cement was used to fill the bone defect and wrap the plate. After infection control, bone grafting to reconstruct the bone defect. Results There were 81 cases of femur, 100 cases of tibia and 2 cases of fibula, after the first stage, 16(8.7%) patients had recurrence of infection after the first stage which have to debridement again. 4 tibial infecton patients had poor wound healing, 2 femoral patients had fixation failure, and 1 patient had femoral fracture due to fall down. After a mean time of 32.0 months (range 12 to 66) follow up, the recurrence rate of infection was 14.2% (26/183). Among them, eighteen patients underwent bone grafting after re-debridement, 6 patients received permanent placement of antibiotic bone cement after debridement, and 2 patients refused further treatment and chose amputation. Bone healing was achieved in 175(95.9%) patients in the last follow-up, and the average time of bone union was 5.4 months (range 4 to 12 months). Conclusions Temporary internal fixation with antibiotic cement coated locking plate has good clinical effect in the treatment of lower extremities long bone infection. It does not increase the difficulty of bone infection control. Pay attention to possible difficulty of skin coverage when applied in calves.
