|A. Standing anteroposterior view radiograph of a 2-year-old boy with Type 1 congenital femoral deficiency (limb length discrepancy = 7 cm) and coxa vara. The neck shaft angle = 95° relative to the proximal shaft of the femur. The proximal femoral physis is relatively horizontally inclined. There is a diaphyseal varus of 20°.
||B. Treatment by proximal femoral valgus external rotation osteotomy. The proximal coxa vara was not corrected, but the diaphyseal varus was corrected. The lengthening is performed through a distal femoral osteotomy. The lengthening is being performed with an Ilizarov apparatus. The external fixation extends to the tibia, with hinges to allow for knee motion.
||C. Final standing anteroposterior view radiographs obtained after limb lengthening (7 cm).
