Eberhardt O, et al. - Researchers evaluated the success of different surgical techniques, including tarsal osteotomies and arthrodesis, in correcting different types of flat feet. The hindfoot deformities were classified into rotational valgus, hinge valgus or translatory valgus based on AP standing X-rays. Findings suggested that for correcting flatfeet following extensive clubfoot surgery with rotational valgus and mild hinge valgus, tarsal osteotomies were successful methods. Authors found an inability of tarsal osteotomies to successfully correct flatfeet that had a translatory valgus. In such cases, double or triple arthrodesis was recommended. They noted a limited functional outcome by the preop range of motion and the appearance of talus deformities.
