The treatment of fractures . abducted, the strainis felt at the internal lateral ligament and at the inferior tibio-fibular interosseous ligament, and these give way. If the forcecontinues, the fibula breaks (see Fig. 529). If the force stillcontinues, the internal malleolus is pushed through the skin,and an open fracture results (see Fig. 530). If the internallateral ligament holds against this lateral force, the tip of theinternal malleolus may be pulled off. POTTS FRACTURE 3Si Symptoms.—The ankle presents a very constant appear-ance after this fracture. A traumatic synovitis exists. Greatswelling appears, at first chiefly upon the inner side of the ankle-joint becomes distended with blood and serum. Allthe natural hollows about the joint are obliterated. The foot iseverted, appearing to have been pushed bodily outward. Theinternal malleolus is unduly prominent. Some of this promi-nence is masked by the swelling. The bony connections andnatural support of the foot having been removed, the foot drops. - Tibia. Cuboid Fig. 538.—Fracture of the tip of each malleolus. Dislocation of the foot backward. Note theprominence in front of the ankle. Same case as figure 537 (X-ray tracing). backward, partly because of the pull of the calf-muscles butchiefly because of its own weight (see Figs. 531, 532). Thedeformity, therefore, is a double one, a lateral sliding of the footoutward and an anteroposterior dropping of the foot malleoli are spread apart : the measured distance betweenthem is increased over the normal. Palpation close above theanterior articular edge of the tibia and the astragalus reveals ten-derness over the ruptured tibiofibular ligament. The backwarddisplacement is best measured by the length of the line from the 382 FRACTURES OF THE LEG front of the ankle to the cleft between the first and second toes(see Fig. 533). This line will be found shortened upon theinjured side. There is tenderness over the fracture of the the in
