The treatment of fractures . 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 internal malleolus is fractured, the sharp ridge at the brokenedge can be distinctly felt. Grasping the posterior part of thefoot firmly with the whole hand while the other hand steadiesthe lower leg just above the ankle, abnormal lateral mobility ofthe foot may be detected (see Fig. 534). The foot will be feltto move inward to its natural position. The moment inwardpressure is removed the foot will be seen and felt to slump out-ward aeain. Diaphysis of fibula. Diaphysis of tibia. Epiphysis. Astragalus. Fig. 539.—Normal ankle-joint, showing epiphyses (anteroposterior view). Figures 535—538 inclusive illustrate a reversed Potts de-formity, the foot having moved inward instead of outward aswell as having fallen backward. Treatment.—The indications for treatment are to place theparts in their normal relations, and to maintain them so untilrepair is completed, guarding against both the lateral and theposterior deformities. If for any reason, such as the presenceof very great swelling of the ankle, it is expedient to delay re-duction, the leg should be placed temporarily in a pillow andside splints (see Figs. 504, 505, 506). An anesthetic shouldalways be administered before the reduction of this fracture. Upper end of lower frag-ment of fibula.
