Clinical effectiveness of modified calcaneal osteo tomy in the treatment of symptomatic flatfoot in children

Objective: to evaluate the effectiveness of the original method of calcaneal osteotomy in treatment of pes planovalgus severe forms in children. Material and methods. The study included 90 patients with flat feet (mean age was 11,5±0,7 years). The 50 children of a similar age without static foot deformities were the comparison group. The patients of the experimental group were operated by using the modified method of treatment pes planovalgus, which includes interfacet osteotomy of the calcaneus with simultaneous correction of the soft-tissue component of the deformity. The postoperative follow-up period was 1,1±0,8 years. The effectiveness of the method was analyzed by use a clinical and instrumental score scale developed specifically for this pathology. Results. Complex clinical and instrumental assessment showed excellent results in 74,7% cases, good – 16,5%, fair – 8,2% and poor – in one child (0,6%). Conclusion. The use of the interfacet osteotomy of the calcaneus in the author’s modification provides the best conditions for achieving good anatomical and functional results in treatment of the severe pes planovalgus in children.
