Radiologic case study. Fractures of the foot masquerading as ankle injuries

An ankle radiographic series frequently is obtained when a patient presents with an acute ankle and foot injury. Although many fractures are confined to the ankle and are readily apparent, fractures of the foot can mimic ankle injuries. It is important to differentiate these fractures of the foot from the more common ankle sprain. Most ankle sprains are treated with ice, compression, and elevation, followed by range-of-motion exercises and progressive weight bearing as tolerated. When foot fractures are not identified, however, lack of appropriate treatment can result in late complications. Concentration on key areas as described here will reduce the incidence of missed fractures of the foot in these patients.
