Lateral Gradual Opening Osteotomy of the Tibia With Monolateral External Fixator for Correcting the Valgus Deformity of the Tibia

The valgus deformity in the tibia requires correction because it places increased pressure on the lateral compartment of the knee, intensifying the degenerative process. Correction strategies are diverse and depend on patient profile, age, and soft-tissue conditions as well as the orthopaedic surgeon’s experience with different surgical materials. Deformity size and location are the primary factors contributing to material and shape choice, whether gradual or acute. The only gradual correction approach involves the use of a monolateral or circular external fixator. This is the only indication for correction in cases of excellent deformity, soft-tissue involvement, and a history of bone infection. This study aimed to present a gradual correction technique for tibial valgus deformity using a monolateral external fixator as well as its postoperative follow-up. This technique has the advantages of greater patient acceptance, lighter assembly, and briefer distraction owing to the use of a single piece as well as the ability of the operated limb to bear a load the day after the surgical procedure and dynamic outpatient follow-up.
