Clinical and Radiological Outcomes of Flexible Flatfoot Correction with Calcaneal Osteotomy

Category: Midfoot/Forefoot; Hindfoot Introduction/Purpose: Various surgical procedures have been used to correct flexible flatfoot deformity; however, the most effective procedure for this deformity remains controversial. This study was performed to evaluate the radiographic and clinical effectiveness of double calcaneal osteotomy (medial displacement calcaneal osteotomy with lateral column lengthening) to correct flexible flatfoot deformities. Methods: Thirty-one patients who had 44 symptomatic flexible flatfeet and underwent double calcaneal osteotomy were examined retrospectively with a mean follow-up of 50 months. Visual analog scale, foot and ankle activity measure, and other clinical data were obtained from medical records. Various radiographic variables for assessing flatfoot and osteoarthritic change in tarsal joints were analyzed from weightbearing radiographs. Results: Results revealed that clinical scores and radiographic variables were significantly improved postoperatively. The mean values of medial sliding and lateral lengthening were 7.6 and 8.7 mm, respectively. No osteoarthritic changes were observed. Conclusion: Double calcaneal osteotomy could be used to correct flatfoot deformities effectively and sustainably and provide symptomatic relief and patient satisfaction.
