Fracture of the leg, ankle and foot is a common injury pattern. These injuries typically result from severe twisting or direct impact. The resulting skeletal injury is typically evident immediately in the form of rapid swelling, pain and difficulty or inability to bear weight in the injured leg. The bone(s) involved and the pattern of the fracture dictates the treatment method of choice. Certain fractures are so stable that no casting or immobilization is required. Non-displaced fractures are often adequately treated with cast immobilization. Displaced fractures, fractures that involve the joint surface, or fractures that disrupt the integrity of the ankle socket typically require surgical treatment.
