    D. Fractures at the Lower End of Both Bones. a. Typical Fracture of the Ankle {Plates 61, 62, 63). This fracture ma}' be compared to the typical frac- ture of the epiphysis of the radius; as in the latter, the mode of occurrence, the symptoms, and the princi- ples of treatment have a typical character. That in fracture of the ankle the fibula breaks likewise is readily understood by reason of the anatomical ar- rangement, i.e., on account of the firm union of tibia and fibula at their lower end. Typical malleolar fracture results from outward flexion of the body when the foot is fixed or from flex- ion of the foot outward. In the latter wa}^ these fractures may be produced in the cadaver: the leg is so placed as to rest on the outer surface, the foot with the malleolar region projecting over the edge of the table; a vigorous push brings the weight of the ex- perimenter's body to bear on the foot, which assumes a certain abducted position, the internal malleolus breaks off, and, the force continuing to act, the fibula fractures slightl}^ above the external malleolus, corre- sponding to the edge of the table. In the majority of malleolar fractures we find the conditions exactly similar. The movement of abduc- tion of the foot in the astragalo-crural joint causes great tension of the internal lateral or deltoid liga- ment; if the movement continues, as a rule the liga- ment is not lacerated, but the tip of the malleolus is turn off. Now the force continuing acts on the foot
