Comparison of orthofix external fixator combined with vascularized fibula graft versus single segmental femoral lengthening for treating femoral defects ≥ 6 cm: a retrospective study

For the treatment of femoral defects measuring ≥ 6 cm, single - segmental bone lengthening with the Orthofix external fixator exhibited advantages in terms of shorter operation time and reduced blood loss compared to FVFG combined with the Orthofix external fixator. Although other outcomes were comparable between the two groups, FVFG demonstrated broader applicability across diverse bone defect classifications, primarily constrained by the defect length and the vascular condition of the recipient site.
