Purpose: To present our experience in the management of acute large bone defects treated with the use of vascularized fibular grafts supported by Ilizarov circular external frames.
Patients and methods: During a period of 6 years (from 2007 to 2013) 8 patients with acute large bone defects (IVB according to Winquist modified classification) were treated at our institution with early bone reconstruction by means of microvascular fibular grafts. All patients were evaluated by the use of the following parameters: X-ray consolidation, discharge time, duration of treatment, malalignment of the lower limb and final leg length discrepancy, knee and ankle mobility (ROM), pain (VAS), number of eventual additive treatments (plastic surgery, etc.), walking independence (use of crutches), possibility to get back to work, subjective evaluation about the treatment and the result (SF-36, personal feelings about circular external fixator dressing) RESULTS: The mean treatment time, often connected to the mean consolidation time, was 61 weeks and the mean number of operations was 7.6. Six of the eight patients got back to their previous daily activities and work, without any further issues.
Discussion: based on our experience, Ilizarov and fibular vascular grafts are not alternatives, as often reported in literature. Their combined use, especially in lesions as those classified as Winquist IV B, can represent an effective tool in the surgeon's hands to solve the most difficult cases of acute bone loss caused by severe high-energy traumas.
