Although double calcaneal osteotomy (medial displacement calcaneal osteotomy with lateral column lengthening) is widely regarded as an effective treatment option for flexible flatfoot, limited studies have extensively analyzed the degree of deformity correction in three dimensions following double calcaneal osteotomy. This study was performed to evaluate the radiographic and clinical effectiveness of double calcaneal osteotomy to correct flexible flatfoot deformities.
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.
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.
Double calcaneal osteotomy could be used to correct flatfoot deformities effectively and sustainably and provide symptomatic relief and patient satisfaction.

尽管双跟骨截骨术（内侧移位跟骨截骨术联合外侧柱延长术）被广泛认为是治疗柔性平足的有效方法，但很少有研究全面分析双跟骨截骨术后三维畸形矫正的程度。本研究旨在评估双跟骨截骨术矫正柔性平足畸形的放射学和临床疗效。
回顾性分析了 31 例 44 例有症状的柔性平足患者，平均随访 50 个月。从病历中获得视觉模拟评分、足踝活动测量和其他临床数据。从负重位 X 线片分析评估平足和跗骨关节骨关节炎变化的各种放射学变量。
术后临床评分和放射学变量均显著改善。内侧滑动和外侧延长的平均数值分别为 7.6 和 8.7 毫米。未观察到骨关节炎变化。
双跟骨截骨术可有效、持续地矫正平足畸形，提供症状缓解和患者满意度。
