Few options exist for the treatment of revision and severe cases of end-stage flatfoot deformity. Triple arthrodesis or medial-approach double arthrodesis have been the standard but often do not provide enough correction of the deformity. Lateral column lengthening is a powerful procedure performed either with an Evans calcaneal osteotomy or calcaneocuboid distraction arthrodesis that can be used as an adjunct in realigning the flatfoot. We performed a retrospective radiographic review and looked at 11 consecutive cases of patients who underwent hindfoot arthrodesis with a lateral column lengthening procedure. We matched these patients with 11 control patients who underwent isolated medial-approach double arthrodesis. For the patients who underwent a lateral column lengthening procedure, we found a significant improvement in calcaneal inclination angle (p = .001) and greater correction in talar declination angle, cuboid abduction angle, and talocalcaneal angle when compared with the control group. Lateral column lengthening is a useful adjunct to hindfoot arthrodesis in the correction of revision and severe end-stage flatfoot deformity.
