Lateral Column Lengthening in Flatfoot Deformity Correction
The Evans osteotomy, a lateral column lengthening procedure, has long served as one of the workhorses in the treatment algorithm for adult-acquired flatfoot deformity.
In their article “Opening Cuboid Wedge Osteotomy (Zoom Osteotomy) for Tri-planar Correction of Flexible Pes Planovalgus Deformities,” authors Mendeszoon et al. introduce a new trip-planar lateral column-lengthening procedure in the cuboid: the “Zoom Osteotomy.”
Central osteotomy that distributes pressure evenly to both the calcaneocuboid joint and the cuboid metatarsal joints diminishes the risk of advanced arthrosis.
More robust vascularity and structural integrity with sufficient cancellous bone to aid with graft incorporation and more structurally stable cortical bone in which re-modelling can occur.
Better maintenance of correction.
Thirty-five patients who underwent a Cuboid Opening Wedge Osteotomy involving 51 feet at a minimum of 12 months after surgery were reviewed. Differences in the preoperative and postoperative cuboid abduction and Meary’s (lateral talometatarsal) angles were statistically significant, and only 3 (6%) complications, including wound dehiscence, neuritis, and deep vein thrombosis, were reported.
