Double-barrel vascularized dual fibula transfer with epiphyseal growth plate for hip reconstruction: A case report

We present a case report of a 10-year-old girl diagnosed with Ewing sarcoma treated with intra-articular wide resection of the right femur and reconstruction with a series-connected double-barrel bilateral vascularized fibula graft (db-BVFG), including fibular head for articulation with the acetabulum of the pelvic bone and preservation of the epiphyseal growth plates for eventual limb growth. No postoperative complications were observed and bone union was achieved with fibular graft hypertrophy, allowing for full weight bearing. Neither local recurrence nor metastasis was observed at 17-year follow-up. Range of motion degrees at last follow up: hip flexion 90 degree, extension 12 degree, abduction 31 degree, rotation 25 degree. Right versus left limb discrepancy was 60 mm. Db-BVFG may be an option for reconstruction of long femoral defects and hip joint restoration following tumor resection and inclusion of epiphysis within the graft is a viable option in pediatric patients to restore longitudinal growth of the reconstructed long bone.
