Abstrakt: Purpose: The study aimed to evaluate preliminary clinical and radiographic results of patients with Cierny-Mader type IV chronic femoral osteomyelitis and augmented with a non-vascularized fibular autograft as a salvage procedure because of the poorly regenerated new bone after bone transport over an intramedullary nail (BTON). Methods: Patients diagnosed with CM type IV chronic femoral bone infection and treated with BTON procedure between 2003 and 2020 were retrospectively reviewed. Seven patients were included in the study whose distraction gap was poorly regenerated and then augmented with a non-vascularized fibular autograft. A three-stage treatment was administered. First, the infection was eradicated. Second, BTON was performed. Third, the poorly regenerated distraction gap was augmented with a fibular autograft before removing the external fixator (EF). Clinical and radiological results were evaluated based on the criteria described by Paley-Maar and Li classification. Results: The mean patient age was 52 years. The mean treatment time was 24.8 months, with a mean femoral lengthening of 12.6 cm. The mean EF and bone healing indexes were 0.57 months/cm and 0.8 months/cm, respectively. The mean length of the fibular graft was 13 cm. The bone healing of new bones was achieved in all patients with good quality after grafting. Functional scores were excellent in four patients. No patients experienced any sequelae. Conclusions: Non-vascularized fibular autograft augmentation may be an effective salvage procedure for poorly regenerated new bone after BTON to manage chronic femoral bone infection.
