In the rare cases of idiopathic valgus foot that fail to respond to conservative treatment surgery is indicated. The author describes an oblique osteotomy of the calcaneum extending from the pre-Achilles region to the inferior margin of the calcaneo-cuboid joint whereby the whole plantar surface of the calcaneum is rotated around its longitudinal axis. This reduces the sliding plane of the talo-calcaneal joint and changes the direction of the Achilles tendon and tibialis posterior so that they exert a more favourable action on the forefoot and tend to actively stabilise the correction. The results in 9 patients (11 feet) aged from 8 to 10 years are most encouraging and the operation preserves the dynamics of the hindfoot in every aspect. The case material is necessarily small because the indications for surgery in this condition are very rare.
在极少数特发性外翻足病例中，若保守治疗无效则需进行手术。作者描述了一种跟骨斜行截骨术，该截骨术从跟腱前区域延伸至跟骰关节下缘，通过此方法，整个跟骨底面围绕其纵轴旋转。这减小了距下关节的滑动平面，并改变了跟腱和胫后肌的方向，从而使它们对前足发挥更有利的作用，并倾向于积极稳定矫正效果。对9例年龄在8至10岁的患者（11只脚）的治疗结果非常令人鼓舞，并且该手术在各个方面都保留了后足的动力学功能。由于这种情况下的手术指征非常罕见，所以病例数量必然很少。
