Congenital aplasia of the tibia.

The authors carried out a study of 15 patients with congenital aplasia of the tibia, 12 total and 6 partial. The clinical and radiographic characteristics of this severe deformity are discussed in relation to the classification and indications for treatment. The authors, whose preference is towards reconstructive surgery, had good results in the partial forms whilst in the total form reconstruction of a new knee joint gave functionally worthwhile results in exceptional cases.
