Posterior calcaneal osteotomy is a technically simple procedure that may be used to correct frontal, transverse, or sagittal plane displacement of the calcaneus associated with flatfoot deformity. In selected individuals, subluxation about the oblique axis of the midtarsal joint may be stabilized. Forefoot supinatus may be expected to reduce secondary to the reduction of heel valgus obtained, although with deformity chronicity, adaptive midtarsal joint changes may necessitate medial column stabilization. Posterior calcaneal osteotomy increases rotational stability of the subtalar joint in a supinatory direction. In addition, displacement of the posterior calcaneal fragment effects a dynamic correction force by translocation of the Achilles tendon and its posterior relation to the axis of the subtalar joint.
跟骨后截骨术是一种技术上简单的手术，可用于纠正与扁平足畸形相关的跟骨在额状面、横切面或矢状面的移位。在特定个体中，中跗关节斜轴周围的半脱位可能会得到稳定。由于获得了足跟外翻的矫正，前足内旋可能会减轻，不过随着畸形的慢性化，适应性的中跗关节变化可能需要对内侧柱进行稳定。跟骨后截骨术可增加距下关节在旋后方向的旋转稳定性。此外，跟骨后段的移位通过跟腱的移位及其与距下关节轴的后方关系产生动态矫正力。
