To improve the technique of Dwyer closing wedge calcaneal osteotomies, specific methods for planning the degree of angular correction and for accurate achievement of this correction are presented. Patterns are made from preoperative radiographs and are cut and re-aligned in the desired fashion to establish the amount of angular correction necessary. The operative technique developed uses drill holes and a standard depth gauge. Measurement of the thickness of the bone at the level of the Dwyer or any other osteotomy thereby allows determination of the size of the base of the resection wedge necessary to achieve the desired angular correction.
为改进Dwyer闭合楔形跟骨截骨术的技术，本文介绍了规划角度矫正度数以及精确实现该矫正的具体方法。根据术前X线片制作模板，按所需方式进行切割并重新对齐，以确定所需的角度矫正量。所开发的手术技术使用钻孔和标准深度测量仪。通过测量Dwyer截骨或任何其他截骨水平处的骨厚度，从而能够确定实现所需角度矫正所需切除楔形基底的大小。
