    Area of Science:

    • Orthopaedic Surgery
    • Microsurgery
    • Vascularized Bone Grafts

    Background:

    • Microvascular techniques like fibular grafts and groin flaps are vital for treating severe extremity trauma and bone tumors.
    • Congenital pseudarthrosis of the tibia presents a significant challenge, with traditional methods often failing.

    Observation:

    • Free vascularized fibular grafts show encouraging early results for challenging bone reconstructions.
    • Unlike osteocutaneous flaps, monitoring fibular graft circulation post-surgery is difficult due to its subcutaneous nature.

    Findings:

    • Current methods like bone scans (24-72 hours post-op) confirm graft viability but don't allow timely intervention if circulation fails.
    • Developing more effective methods for monitoring microvascular anastomoses patency is essential.

    Implications:

    • Technological advancements like thermocouples and laser Doppler flowmetry are being explored for real-time graft monitoring.
    • Microsurgery as a technique, when applied by trained orthopaedic surgeons, broadens the application of vascularized bone grafts for musculoskeletal defects.
