A significant percentage of patients who "sprain" an ankle sustain a permanent disability.1 In 1942 Hughes2 wrote that in 57 cases of injury to the ankle without evidence of bony change about half of the patients showed some tilting of the talus when roentgenograms were made with the ankle in forced inversion. Leonard3 and Pennal4 assert that tears of the fibular collateral ligament of the ankle severe enough to be demonstrable roentgenologically in forced inversion should be treated in plaster for 6 to 10 weeks. If the injury to the ligaments is extensive, involving a complete tear of the anterior talofibular and calcaneofibular ligaments, it has been proposed that the ligament be repaired primarily.
According to Kelley and Janes,5 there is extant a group of patients who eventually develop chronic subluxating ankles, most of them sustaining the disability as the result of improper treatment. Excellent
