title: Outcomes of anterolateral thigh-free flaps and conversion from external to internal fixation with bone grafting in gustilo type IIIB open tibial fractures.
abstract: The purpose of this study was to analyze the utility and the clinical outcomes of anterolateral thigh (ALT)-free flaps and conversion from external to internal fixation with plating and bone grafting in Gustilo type IIIB open tibial fractures. A total of 21 patients were analyzed retrospectively. The mean follow-up period was 18 months and the mean age was 46.7 years. There were 18 men and three women. The mean time from injury to flap coverage was 11.6 days. The mean size of flaps used was 15.3 × 8.2 cm. The mean size of bone defects was 2.26 cm. Segmental bone defects were observed in 5 five cases, for which bone transport or vascularized fibular graft were performed. When flaps were successful and the fracture sites did not have any evidence of infection, internal fixation with plates and bone grafting were performed. Flaps survived in 20 cases. In the 20 cases with successful flaps, two cases developed osteomyelitis, but the 20 cases achieved solid bone union at a mean of 8.6 months after the injury, salvaging the lower extremity in 100% of the cases. At the last follow-up, 9 nine cases were measured excellent or good; 6, fair; and 6, poor in the functional assessment based on the method developed by Puno et al. ALT- free flaps to cover soft tissue defects in Gustilo type IIIB open tibial fractures are considered as useful option for the treatment of composite defects. In addition, conversion to internal fixation and bone grafting can be an alternative method in order to reduce the risk of complications and inconvenience of external fixators.
