Fibular transfer for congenital absence of the tibia.

In patients with congenital absence of the tibia, construction of a knee joint by transferring the fibula under the femoral condyle gives satisfactory results, provided a strong quadriceps is present. In the rare patient with an associated proximal focal femoral deficiency on the same side, even in the absence of a strong quadriceps, this procedure with a fibulofemoral fusion will give a longer stump, allowing better prosthetic fitting. The procedure is performed as early as the first year of life.
