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

Background: Bone lengthening and free vascularized fibula graft (FVFG) represent two prevalent modalities for bone defect repair. The objective of this study was to compare the efficacy disparities between FVFG and single - segmental bone lengthening (BL) when the Orthofix external fixator was utilized in the treatment process.

Methods: The follow - up data of 72 patients with femoral defects, who received treatment from January 2009 to May 2019, were collected for retrospective analysis.
