Malposition might cause future metatarsalgia, mid-foot pain and discomfort, which may dictate an on-going need for in-shoe orthosis, shoe modification and, occasionally, operative correction. To minimize and prevent these problems, we describe a simple technique for reduction and fixation of metatarsal fractures by Kirschner wires. We have found this technique to be a simple and efficient way of reducing and fixing metatarsal fractures. It is applied easily by the closed and open technique.展开更多
