    Summary

    Vascularized bone grafts effectively treat large bone defects from tumors or trauma. Microvascular techniques offer a successful solution for limb reconstruction, though amputation remains a risk.

    Area of Science:

    • Orthopedic Surgery
    • Microsurgery
    • Reconstructive Surgery

    Background:

    • Autogenous vascularized bone grafts are crucial for reconstructing massive segmental bone defects.
    • These defects often result from aggressive bone tumors or severe trauma.
    • Microvascular anastomosis techniques enable the transfer of viable bone segments.

    Observation:

    • Forty-one vascularized bone grafts were performed, including 22 free vascularized fibular grafts (lower extremity) and 10 (upper extremity).
    • Ten patients had bone tumors, and the rest had trauma-induced defects averaging over 14 cm.
    • Osteocutaneous groin flaps were used in nine patients.

    Findings:

    • The overall success rate for vascularized bone grafts was high, effectively treating large bone defects.
    • Four patients (12.5%) required amputation due to graft failure.
    • One of nine patients treated with osteocutaneous groin flaps also required amputation.

    Implications:

    • Vascularized autogenous bone grafts are a viable and effective treatment for massive segmental bone defects.
    • Microsurgical techniques improve outcomes in complex limb reconstruction.
    • Careful patient selection and surgical technique are essential to minimize risks like amputation.
