Complex Foot Deformity Correction Using the Ilizarov Circular External Fixator with Distraction but Without Osteotomy

The Ilizarov device is an effective method for correcting clubfoot deformities because the technique permits simultaneous correction in all three dimensions.6 The Ilizarov method can be used to correct clubfeet in two ways: as a means to distract the soft tissues alone or in conjunction with osteotomies. When the Ilizarov is used to distract soft tissues, correction occurs through the elimination of contractures and by establishing new positions of the joints that result in a plantar grade position.2,3,5,8 Soft tissue release of this type is based on the view that cartilaginous bones can be remodeled. Distraction methods reshape bones by activating the circumferential physis of the affected bones.7 The addition of osteotomies permits the growth of new bone, which accomplishes wedge-type corrections.4,5,7,8 The joints remain undisturbed with the osteotomy distraction technique.
