The greatly increased distance between theanterior inferior spinous process of the ilium and the anteriorinter-trochanteric line of the femur cannot be accommodated byanything less than the rupture of this portion of the head of the femur can be placed over the thyroid foramen 1884.] Gunn, Reduction of Dislocations. 461 in the intact state of this portion of the ligament; but in orderto accomplish this, the femur must be flexed to a right angle withthe longitude of the trunk. This is illustrated in Fig. Fig. 5.—Showing what would be the degree of flexion in thyroid dislocation ifthe ilio-femoral portion of capsule remained An examination of this figure, or of the specimen which Iherewith exhibit, will fully warrant the positive statement, thatin the downward and forward luxation, if the limb is foundinthe position generally characteristic of this form of the accident,the only untorn part of the capsule will be the upward and back-ward portion, as is illustrated in figure 4. To reduce this dislocation, the reducing force should be appliedin the usual way to the inner aspect of the upper part of thethigh at its junction with the perineum, with the intention oflifting the head directly into the socket; but instead of adductingthe limb, as is the usual practice, free abduction should be made,thus fulfilling both of the general principles which I have laiddown. With these manipulations, there is nothing in the way ofan easy return of the
