Management of Varus Ankle Osteoarthritis with Joint-Preserving Osteotomy

Single-Stage Supramalleolar Osteotomy for Coronal Plane Deformity

“…In the meantime, the clinical studies are not limited only to simple description of supramalleolar osteotomies and their postoperative clinical and radiographic results. Detailed treatment algorithms considering all concomitant pathologies have been described for patient with valgus deformity [13,28], varus deformity [12,29], or peritalar instability [30,31].…”

Safe Zone for Medial Open-Wedge Supramalleolar Osteotomy of the Ankle

“…7 For medial open-wedge SMO, there is some debate as to whether concurrent fibular osteotomy should be performed. Myerson et al 11 reported that a greenstick osteotomy without fibular osteotomy markedly increases the stability of the cut, and the tibia can be opened with a lamina spreader to the desired amount of correction. If there is a concern that the lateral cortex will break, or if the planned opening wedge is too great to avoid making a complete cut, a 2-or 3-hole plate can be applied to the lateral aspect of the distal tibia at the level where the osteotomy exits.…”

Effect of Combined Fibular Osteotomy on the Pressure of the Tibiotalar and Talofibular Joints in Supramalleolar Osteotomy of the Ankle: A Cadaveric Study

“…To prevent displacement of the osteotomy gap during the experimental axial load, a unilateral external fixator was also applied to the medial aspect of distal tibia. After measuring the joint contact pressures under 3 different tibial osteotomy conditions (6-, 8-, and 10-mm osteotomy gaps), a fibular osteotomy was performed in an inferomedial direction at the same level as that of the tibial osteotomy (9,14). After bending a one-third tubular plate to fit the valgus angulation of the fibular osteotomy site, which was determined by the height of the osteotomy gap, the plate was fixed with screws.…”
