In 1975, Evans published an article describing the surgical management of the "calcaneo-valgus deformity," pointing out that the deformity was due to relative shortening of the lateral column of the foot. Correction involved "equalizing" both columns by performing an osteotomy in the neck of the calcaneus 1.5 cm from the calcaneocuboid joint, where a trapezoidal wedge of tricortical bone was placed. Although it was considered a success, there were complications, including sural nerve injury, surgical wound dehiscence, undercorrection, and graft subsidence. The osteotomy grew in popularity. Indications extended to other forms of flatfoot with a low incidence of complications.
1975年，埃文斯发表了一篇描述“跟骨外翻畸形”手术治疗的文章，指出该畸形是由于足部外侧柱相对缩短所致。矫正方法是在距跟骰关节1.5厘米的跟骨颈部进行截骨术，通过放置一块三层皮质骨的梯形楔块来“平衡”两柱。尽管该方法被认为是成功的，但仍存在一些并发症，包括腓肠神经损伤、手术伤口裂开、矫正不足和植骨下沉。这种截骨术越来越受欢迎。其适应证扩展到其他形式的扁平足，并发症发生率较低。
