The Free Fibula Flap for Lower Extremity Reconstruction.

Reconstruction of critical size bone defects in the lower extremity poses a significant risk to not only limb malfunction but also amputation. The reconstructive goal of free bone flaps is to provide vascularized bone that restores length and stability. This applies to the native limb and also in amputations when a vascularized length of bone is required to maintain level of amputation. Multiple anatomic regions of the lower extremity may be successfully reconstructed with the fibula free flap.
