AbstractRadiographic series of the foot are often obtained in conjunction with ankle X-rays when the clinical presentation is limited to trauma to the ankle. The Ottawa Ankle and Foot Rules were established in 1992 and serve as reliable guidelines to determine when an ankle or foot series is warranted in patients who have sustained minor ankle and/or foot injury. We retrospectively reviewed radiographic studies of all patients over a period of 18 months who simultaneously had ankle and foot plain radiographs performed for acute complaints limited to the ankle alone. Of the 243 patients who met our inclusion criteria, 55 patients had fractures, 46 in or near the ankle joint, and nine which were located at the base of the fifth metatarsal bone. No fractures or dislocations were noted elsewhere in the foot. All of the fifth metatarsal fractures were evident on adequately performed ankle series. Our findings suggest that films of the foot are not necessary when trauma is limited to the ankle and when an appropriately performed ankle series has been completed.
