[Metacarpal shaft reconstruction using medial femoral condyle flap: A case report]. / Reconstruction diaphysaire métacarpienne par transfert osseux vascularisé de condyle fémoral interne : à propos d'un cas.

We report the technique applied to reconstruct a whole shaft defect of the 4th metacarpal bone in a 22-year-old women after aneurysmal bone cyst resection. Local invasion leads to possible poor revascularization possibilities, justifying the use of a vascularized bone transfer. Surgical procedure consisted in a 5-centimeter free medial femoral bone flap transfer. Two months after surgery, no after effect was found at donor site and bone consolidation was complete. Bone fixation allowed early active motion and a complete recovery of flexion-extension range was present 1 year after surgery. Free medial femoral condyle was described several times as a solution for metacarpal defects, in osseous or osteocutaneous versions, it represents a useful option in hand surgeons' armamentarium.
