Content
Figures 8A, 8B, and 8C are dorsal pre-operative, dorsal post-operative, and lateral post-operative views, respectively, of a foot treated with an Evans calcaneal osteotomy, according to one embodiment. Outward rotation of the foot may occur in patients with flatfoot. An Evans or lateral column lengthening procedure is sometimes performed for these patients. An incision is made on the outside of the foot, and the front half of the heel bone is cut. A bone wedge (typically either titanium or a bone-based graft) is then placed into the cut area of the heel bone. This wedge helps to “lengthen” the heel bone and rotate the foot back into its correct position. The wedge is usually kept in place using screws or a surgical staple.
