Limb salvage treatment for congenital deficiency of the tibia.
Nine limb salvage treatments were performed in 7 patients with congenital deficiency of the tibia. All feet showed equinovarus deformity and were centralized in a slightly equinus position by placing the distal end of the fibula into the posterior facet of the calcaneus. Tibiofibular fusion was performed in 4 patients with partial deficiency, and fibular transfer (fibular centralization; Brown procedure) in 5 with complete deficiency of the tibia. Callus distraction lengthening was performed repeatedly for leg-length discrepancy on either the femur or the centralized fibula. Satisfactory functional and cosmetic results were obtained in all limbs with partial deficiency, whereas in limbs with completely deficiency, none of the 5 knees treated by fibular transfer achieved a satisfactory functional result because of insufficient quadriceps strength, progressive knee flexion contracture, and persistent ligamentous instability. Nevertheless, in these 5 cases, all patients were ultimately able to withstand weight-bearing.
